  • Apple brings updates for HomePod and Apple TV

    After iOS 13.5, Apple also presented new operating systems for its smart speaker and multimedia box.

    Big update week at Apple with updates for almost all devices. After watchOS 6.2.5 and iOS 13.5 or iPadOS 13.5, new operating systems for Apple TV and HomePod are now also available for download. Unfortunately, Apple likes to hold back with release notes for these accessory products. This is also the case this time: both tvOS 13.4.5 for the multimedia box and HomePod OS 13.4.5 for the Siri speakers have been published without any comment.

    What's new?
    However, it can be expected that the updates will contain stability and performance improvements as usual; it is still unclear whether there will also be new features. However, security gaps have been fixed - this can be found, at least for tvOS, from Apple's official security updates overview. There it is said that details will be published "soon". Incidentally, this also applies to watchOS 6.2.5, watchOS 5.3.7 for older computer watches as well as iOS 13.5 and iPadOS 13.5 - Apple once again does not present its fix list immediately when the operating system is published. Why this is so remains unclear.

    TvOS such as HomePod OS are installed either automatically, if the user has selected this, or via the system settings (Apple TV) or the home app on the iPhone (HomePod). A quick installation makes sense because of the closed security gaps, problem reports are currently not available. With HomePod OS, Apple is also happy to ensure that HomeKit problems are also fixed with the updates. The smart speaker operating system has recently been based on tvOS, after having been an iOS derivative for a long time.

    Catalina is still missing
    What is currently missing is a new version of macOS 10.15 alias Catalina. Version 10.15.5 is currently being tested in the fifth beta. It is quite unusual for Apple not to release operating systems together. This time a new watchOS came first, then iPadOS or iOS with the new corona tracking features. MacOS 10.15.5 can be expected soon.

  • Apple provides updates for older iPhones and iPads

    Once again, owners of devices that do not support iOS 13 can update their operating system. Presumably it's about security.

    Users of older iPhones, iPads and iPod touch devices take note: Apple has a fresh operating system update ready for them too. For all products that no longer support iOS 13 but can work with iOS 12, iOS 12.4.7 has been available for download since last week. This covers iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3 and the sixth generation iPod touch.

    Importing: that's better
    Apple has not yet announced what is specifically new in the update. The only mentioned detail in the release notes are "important security updates" that should be included in iOS 12.4.7. At around 50 MB, the download is quite narrow on most devices.

    As with all security-related updates, users should import the update urgently. Basically, it is praiseworthy that Apple still provides the old devices with security updates; However, this does not happen regularly and seems to be made by the company depending on how severe the respective gap is.

    Apple keeps details under lock and key
    It is currently still unclear which patches are included in the latest versions of iOS, iPadOS, watchOS and tvOS. This applies to iOS and iPadOS 13.5 as well as to watchOS 6.2.5 and 5.37 as well as tvOS 13.4.5 and iOS 12.4.7. Apple has still not published the relevant details, and has been saying on its support page for days that the information should be available "soon".

    This delay tactic is not new, it has been used for some updates for a long time. Security experts criticize this. In the past, detailed information was usually available immediately for an update to be published. It is unclear whether Apple would like to curb exploit risks with the later release - by giving users more time to install updates.

  • iOS 13.5.1 kills jailbreak

    Apple has released an additional update that undermines the unc0ver hack. Updates are also available for iPad, Mac, Apple Watch, and Apple TV.

    On Tuesday night, Apple surprisingly presented another update for iOS and iPadOS. The release notes initially only stated that the update provided "important security updates" and was therefore recommended "for all users". As it turned out a short time later, the new software with the version number 13.5.1 is used to fill the zero-day gap in iOS and iPadOS 13.5 used by the unc0ver 5 jailbreak.

    A credit for unc0ver
    Apple confirmed this in a very brief patch note on its security website. There it is stated succinctly that the bug allowed an application to execute "arbitrary code with kernel privileges". The reason is a memory consumption problem that has been addressed with "improved memory handling".

    "Unc0ver" is listed under credits. iOS (or iPadOS) 13.5 was unusually crackable through a jailbreak immediately after arrival, so it was delivered with a hole. Apple's security department should hardly have liked that. A little later, a jailbreak for the latest version of tvOS was also available.

    Further updates for all devices
    In addition to iOS and iPadOS 13.5.1, Apple has also submitted other updates, all of which address the kernel vulnerability. These are watchOS 6.2.6, tvOS 13.4.6 and HomePod OS 13.4.6. The error is also in macOS. Therefore Apple distributes "Supplemental Updates" for this.

    These are available for macOS 10.15.5 as well as for the Security Update 2020-003 High Sierra, but not for the Security Update 2020-003 Mojave, which is also distributed together with macOS 10.15.5. It remains unclear whether this means that the vulnerability does not exist there - however, it is strange that the company supplies an earlier macOS variant (High Sierra, 10.13), but not the newer Mojave (10.14).

    Update: June 9th, 2020

    Apple closes the way back to jailbreak

    IOS 13.5.1 was recently released, which fixed an unpatched kernel exploit. The previous version can no longer be installed.

    Apple stopped digitally signing iOS and iPadOS 13.5 on Tuesday. It is no longer possible to install these operating system versions on iPhones and iPads. This is unusual in that Apple typically waits several weeks for this signature process to finish after a newer version of iOS becomes available - but this time everything is different.

    Signing ended quickly
    Because Apple had eliminated the unc0ver 5 jailbreak with iOS 13.5.1, which was only released at the beginning of June. This had used a zero-day kernel exploit with which the previous version iOS 13.5 was delivered. The group reacted quickly with an update. The end of the signing of iOS 13.5 now ensures that users can no longer easily downgrade - unless they have secured the so-called SHSH blobs.

    All current iPhones affected
    unc0ver 5 was able to crack all current iPhones - including the 2019 and 2020 models, i.e. the iPhone 11, 11 Pro, 11 Pro Max and SE 2020. The iPad went up to the iPad Pro 2020. The jailbreak is done via an app that is sideloaded got onto the device. With the end of signing, Apple usually tries to persuade users to always be on the latest iOS version - also for security reasons. The fact that the company is now interrupting the jailbreak cycle at an early stage is only logical - as annoying as that is for those interested in jailbreaking.

    Old devices can still be cracked
    They still have other options anyway if they don't want to use the very latest iOS device. Because: In the late summer of 2019, an unpatchable boot ROM exploit surfaced that makes it possible to jailbreak any iOS version, but only on older model series up to iPhone 8 and X. The jailbreak tool checkra1n based on it currently supports only operating system versions up to iOS 13.5.

  • Apple provides iOS 13.6

    The update for the iPhone and iPad operating system brings various new features, including CarKey for BMW cars and in the health and news area.

    Actually, iOS 13 is already well advanced, but Apple still suffices major updates: Version 13.6 was released for download on Wednesday evening. The update comes one month after iOS 13.5.1 and is also available for Apple's tablets as iPadOS 13.6.

    iPhone as a car key
    The most important new function is the support for CarKey, a feature with which vehicles can be opened and started directly via iPhone via NFC. Currently, this is only possible with BMW models from the 1, 2, 3, 4, 5, 6, 8, X5, X6, X7, X5M, X6M and Z4 series that left the factory after July 1st. It is currently unclear whether older models will also be added via update. iPhone XS, XR or newer are a minimum requirement, and the official BMW Connected app must be running on the device. The pure key function can be used up to five hours after the end of the battery.

    The next innovation in iOS 13.6 and iPadOS 13.6 is a new switch that gives the user the option of deciding whether iOS and iPadOS will automatically download updates via WiFi and keep them on the device. Before that it ran automatically, which reduced the free space. Another new feature is an install button, which enables new iPhone or iPad software to be installed automatically on the device overnight when it is connected to the power supply.

    Health and Apple News
    There is a new section "Symptoms" in the health app on the iPhone. Here, a user can record various diseases - such as muscle pain, loss of appetite, cough, headache and the like - everything to make a diagnosis easier for a doctor if necessary. The overview also shows symptoms that have been recorded when using the ECG of the Apple Watch or with the function for tracking the period.

    Apple News, which does not yet officially exist in Germany, has now integrated audio stories - Apple has some of the best stories from the News + subscription service read aloud. Apple News Today is available as a free daily news briefing; it can be heard through the Podcasts app. The audio content from News or News + can also be played back via the CarPlay vehicle integration. In the US, there will also be curated local news in five regions in the future.

    Bug fixes and security fixes
    Apple continues to promise some bug fixes. These are related to iCloud drive synchronization (freezes during transfer), eSIM use (data roaming display unreliable), WiFi calls (registration problems with iPhone 6S and SE, poor audio) and the control center (stability problems with active Assistive Touch).

    IOS 13.6 and iPadOS 13.6 also fix a number of security holes that Apple has published without delay for the first time in a long time. Some gaps that could be exploited remotely related to audio playback (code execution), the AVEVideoEncoder (code execution with kernel privileges), GeoServices (GPS data can be read out), Bluetooth (denial of service due to a crash), ImageIO (code execution) , Mail (Denial of Service) and Messages (remote users could re-join groups). Kernel, USB audio and WiFi bugs have also been fixed; Apple mentions three areas of error without giving further details.

  • macOS 10.15.6, watchOS 6.2.8 and tvOS 13.4.8 available

    In addition to iOS and iPadOS 13.6, Apple has also updated its other operating systems - plus HomePod OS and Safari.

    Owners of Mac, Apple Watch, Apple TV and HomePod should take a look at the software update on their device: On Thursday night, Apple distributed fresh updates for these products in addition to iOS 13.6 and iPadOS 13.6.

    Bug fixes in macOS Catalina
    MacOS Catalina now ends up with version 10.15.6. This brings a new version of the Apple News app in the USA, Canada, Great Britain and Australia. It offers more local news and curation in various US cities and a daily newsletter from Apple News that can be personalized. Several bugs have also been fixed. It could happen that the computer name changed suddenly after installing a software update. A bug in which USB mice and other peripheral devices with USB 2.0 lost the connection should also no longer occur.

    Lots of security fixes
    In addition, security gaps have been fixed. Apple names a total of 17 areas here. Affected are audio support, WLAN, CoreFoundation, graphics drivers, ImageIO, Mail, Messages, USB audio, open source tools such as VIM and Heimdal as well as the kernel. Various bugs allow malicious code or denial-of-service attacks to be executed, and some can also be exploited remotely. In addition to macOS 10.15.6, Apple also provides security updates for Mojave (Security Update 2020-004) and High Sierra (Security Update 2020-004). The Safari browser now reaches version 13.1.2. It is included in macOS 10.15.6 and is available separately for Mojave and High Sierra. Several WebKit gaps are fixed here.

    watchOS, tvOS and Co.
    watchOS 6.2.8 brings support for the CarKey functionality, with which BMW models can be unlocked via NFC - from Apple Watch Series 5. In Bahrain, Brazil and South Africa, the ECG function and notification of irregular heartbeats are also activated . A number of security-related bug fixes are also included. What is new in tvOS 13.4.8 for Apple TV HD and Apple TV 4K is still unclear - so far, Apple has only published details of fixed security holes. The Smartspeaker HomePod also ends up at version 13.4.8 - so far there is no information here.

    Updates for older hardware
    In addition, Apple has iOS 12.4.8 for older devices (iPhone 5s, 6 and 6 Plus, iPad Air, iPad mini 2 and 3, iPod touch 6G) as well as watchOS 5.3.8 (for Apple Watch series 1 to 4) and Xcode 11.6 published. Details are also missing for these; Nothing is listed on Apple.com when it comes to security fixes either.

  • iOS 13.6.1 is supposed to eliminate problems with Corona contact messages

    The iPhone and iPad update is intended to fix problems with full memory, greenish displays and disabled encounter notifications.

    With a bug fix update, Apple has improved iOS 13 again: The iOS and iPadOS 13.6.1 released on Thursday night provides three important bug fixes, according to the manufacturer. It can be obtained from the iPhone and iPad via the integrated software update function, the size varies depending on the model type, on an iPhone X, for example, it is a good 100 MB. Alternatively, it is still possible to download it with iTunes and import it via a wired connection.

    Disabled corona encounter messages
    iOS 13.6.1 is supposed to remove a problem on iPhones, through which the corona encounter messages "can be deactivated for some users".

    Apple does not provide any further details, so it remains to be seen whether affected users have not received a notification after contact with an infected person or whether the complete recording of all encounters was stopped due to the bug.

    Individual users reported with iOS 13.6 that the Corona warning app suddenly warns that the risk identification has been stopped - but at the same time lists it as active. Other users received an error when activating the risk determination in the Corona warning app - and could no longer switch it on. It is still unclear whether these errors will be eliminated by the update.

    Greenish iPhone displays
    A problem with the temperature control could cause a green discoloration on "some displays", Apple also notes, and version 13.6.1 is supposed to eliminate that too. Primarily users of iPhone 11 and iPhone 11 Pro had reported the symptom, after unlocking the device, the screen may have been noticeably greenish. In most cases, the discoloration should disappear again within a few seconds.

    Apple has also tackled the possibility of the iPhone and iPad storage space becoming full: If the available storage space becomes scarce, the operating system should reliably and automatically delete system files that are not required to create free space.

    IOS 13.6.1 does not bring any security-relevant innovations. It should be one of the last updates for iOS 13, Apple is working in parallel on the completion of iOS 14, which should appear in the fall - for all devices that also run iOS 13.

  • iOS 13.7 available: Corona tracking directly in the operating system

    In the future, health authorities will be able to implement contact tracking without their own app on the iPhone. Google does the same thing.

    Apple released what will probably be the last version of iOS 13 on Tuesday evening before iOS 14 is due. iOS 13.7 is also available for Apple tablets as iPadOS 13.7 and brings some new functions to the iPhone. For example, Apple has implemented the so-called Exposure Notifications Express system for the first time, with which health authorities should be able to offer coronavirus contact tracking even without their own app. In the USA, the states of Maryland, Nevada, Virginia and Washington, D.C want to be the first to use the feature, with European regions likely to follow suit.

    As before, Apple is working with Google - they also want to integrate the function directly into the operating system. In supported regions, users are asked if they want to participate in the follow-up. Existing corona warning apps will continue to work, as the companies announced on Tuesday. The new method should lead to a faster spread of contact tracing, since in the future every country and every authority will no longer have to develop its own app. Corona warning apps already used integrated functions in iOS and Android, but an app was always required for reading.

    Warning now also without an app
    The technology is said to help stop the spread of coronavirus by warning users if they are next to an infected person. Smartphones on which the function has been activated exchange Bluetooth keys with one another. According to the current guidelines of the health authorities, there is a warning if it turns out that you have been near an infected person for 15 minutes.

    The duration and distance can be adjusted by the authorities. The success of the apps also depends on users sharing their positive results from a Corona app in the app. The keys are only compared on the smartphones to ensure data protection.

    Opt-in remains
    iOS 13.7 now contains a corresponding switch to enable contact tracking across the operating system. It can be found in the settings. The function also warns automatically as soon as there is a suitable app in the user's region - those that have the express function are then also visible. There is still an opt-in - you can only follow up on contacts if you wish.

    iPadOS 13.7 is also available for download. Which new functions are included here has not yet been communicated - they are probably bug fixes. Security-relevant bug fixes were apparently not made - not even in iOS 13.7.

  • Corona warning app: bug in iOS 13.7 disrupts corona tracing

    SAP and Deutsche Telekom are warning of a problem in which the COVID-19 risk is presented higher than it actually is. Only iPhones are affected.

    The official blog for the German Corona warning app indicates a current problem in connection with the latest version of Apple's mobile operating system. iOS 13.7 on the iPhone could mean that users may see a higher risk than they actually had, according to the makers of SAP and Deutsche Telekom. "Under the new iOS version released by Apple on September 1, there may be misleading risk calculations for a small number of users," the developers write. The problem was discovered during regular tests of the app by the developer team.

    Improvements integrated by Apple - and bugs
    Users of the application on Android devices and iPhones with an older iOS (up to and including version 13.6.1) are reportedly not affected by the bug. "We are currently working flat out with Apple on a solution so that the affected users under iOS 13.7 can get a correctly calculated risk assessment again."

    Actually, iOS 13.7 should bring improvements in contact tracing. This makes it possible for the first time to implement this without a separate app. Local health authorities only need to send a configuration file to Apple that contains, for example, information about risk assessments and the procedure in the event of a possible infection. The revised framework then generates the application itself, which is integrated directly into iOS. Google does the same with Android. In Germany, however, the app is still required. The main aim is to facilitate corona tracing in countries where there are no resources for their own application.

    The developers actually recommended the app
    How it came about that iOS 13.7 worsened contact tracking is currently unclear. A week ago, the developers at SAP and Deutsche Telekom recommended that iPhone users install the latest operating system version 13.7, because Apple had "significantly improved" the technical interface (API) in the past few weeks.

    It was not clear on Friday when Apple would publish an update in which the bug that has now been discovered will be eliminated - nor whether there can be a fix from SAP and Deutsche Telekom. The app, which is published by the Robert Koch Institute (RKI), has now been downloaded over 18 million times. Since the release in June, several bugs had been discovered and fixed again.

  • iOS 14 and iPadOS 14: Golden Master can be loaded

    Apple's new mobile operating systems are coming faster than expected this year.

    One of the few surprises at Apple's keynote from yesterday, Tuesday, is the fact that iOS 14, iPadOS 14, as well as watchOS 7 and tvOS 14 will be shipped this Wednesday. Golden master versions of the operating systems were placed on the developer servers during the night. The rapid availability is amazing, as the iPhone manufacturer usually waits for the release of new smartphone models before the new iOS appears. But this year everything is different: The "iPhone 12" is not expected before October (or even November).

    iOS 14 turns the home screen upside down
    The updates offer a number of long-awaited innovations. iOS 14, for example, gets a completely new home screen design. The widgets, which were previously housed in their own view, can in future be configured in different sizes and also placed directly on the home screen next to apps. A new picture-in-picture view also allows videos to continue playing when the app is changed; Apple has so far reserved that for the iPad. For the first time it is possible to sort apps automatically, for example by categories - this creates a significantly better overview.

    The Messages app in iOS 14 allows important conversations to be pinned to the top. In addition, Apple has further expanded the Memoji function to adapt the comic-like counterparts - for example with a face mask. In group conversations, it is possible to reply to individual messages directly; this is done in a new inline thread view and is intended to provide a better overview.

    iPadOS 14 becomes more productive
    iPadOS 14 also offers home screen improvements, supports writing capture with the Apple Pencil much better and provides some new productivity functions. Calls and Siri are less annoying because they have their own windows and don't hijack the entire screen. Both iOS 14 and iPadOS 14 can set standard browsers and standard e-mail programs that do not have to come from Apple.

    watchOS 7: More tracking and more watch faces
    In the likewise new watchOS 7, new tracking features for sleeping and washing hands are implemented. Clock faces can be adjusted more flexibly, developers can offer several different so-called complications - small information displays - for their apps. In addition to other new clock faces and minor adjustments, Apple will in future allow the clock face configurations to be shared with third parties - via e-mail, iMessage, but also, for example, via websites and the App Store. The update is intended to expand the protective functions for the hearing through an extended control of the headphone volume and integrates innovations that Apple has also announced for iOS 14, including bicycle navigation in maps and Siri as a translator.

    tvOS 14 is fun
    Apple's multimedia box Apple TV is also getting a fresh update. The practical picture-in-picture function now works system-wide in tvOS 14: the video that is currently running can be viewed in a small window when you switch to the app. HomeKit security camera users can use Siri or the control center to display a small live image from the camera or a video doorbell on the television. Audio sharing is possible with AirPods. Multi-user mode supports Apple's Arcade game service in tvOS 14 so that everyone can access their own saved games

    All information about the new operating system versions can be found in Mac & i issue 4/2020, which is currently on the kiosk and can be ordered in the heise shop.

  • iOS 14.0.1 and macOS 10.15.7 fix bugs

    Apple presented operating system updates for Mac, iPhone and accessories on Friday night.

    Apple released bug fix updates for all of its operating systems on Friday night. Known bugs are partly fixed, partly also security holes are plugged.

    iOS 14.0.1 and iPadOS 14.0.1 solve a problem in which the new default browser and default e-mail settings reverted back to Apple software after a restart. Camera previews were sometimes not possible on the iPhone 7 and 7 Plus. Another bug related to the connection to WiFi networks, which were partially interrupted. In addition, pictures were sometimes missing in the news widget and some e-mail providers refused to work.

    tvOS and watchOS also included
    IOS and iPadOS 14.0.1 do not appear to be included in security updates. WatchOS 7.0.1 is also available. A bug is fixed here that could lead to the removal of means of payment from the wallet. tvOS 7.0.1 is also available, but Apple does not mention anything new. WatchOS 7.0.1 and tvOS 7.0.1 also do not contain any security updates that require CVE IDs.

    Updates for macOS
    MacOS Catalina 10.15.7 is also available for download - it is unusual for Apple to choose a new version number here shortly before macOS 11. This fixes a WiFi problem where some Macs no longer automatically connected to a router. In addition, a synchronization problem with the iCloud Drive should no longer occur. The new iMacs with Radeon Pro 5700 XT from 2020 (27-inch model) also apparently no longer show an annoying graphic error.

    Security related bugs
    There are a total of four security-related fixes in macOS 10.15.7. They concern Model I / O, Sandbox and ImageIO. Among other things, code could be executed with the holes. Security Update 2020-005 High Sierra and Security Update 2020-005 Mojave are also available, which fix the three vulnerabilities. In High Sierra (macOS 10.13) a mail bug is also fixed, with which the "application status could be changed unexpectedly" remotely.

  • iOS 14.0.1 fixes a few bugs and creates new ones

    The current operating system patch iOS 14.0.1 does not manage to fix the battery and connectivity problems. Some bugs have been fixed, but new problems have arisen.

    The new Apple operating system iOS 14 is getting off to a turbulent start. The developer community complained that the preparation time was too short. Now Apple is starting to bring out updates to fix startup issues. The new patch iOS 14.0.1 fixes a number of things that were stuck in iOS 14, but it also seems to introduce new bugs.

    So on the fix side, iOS 14.0.1 should fix a number of issues:
    • Restart settings back to Apple apps
    • Camera previews are not showing on the iPhone 7 and iPhone 7 Plus
    • Wi-Fi connectivity issues
    • Mail problems with some providers
    • News widget issues
    So these are the fixes listed, what about the new issues?
    There seems to be a lot of that.

    These problems range from the common problems - poor battery life, Wi-Fi and Bluetooth issues - to more exotic problems like keyboard lag, system instability, and widespread widget issues.

    Resetting network settings - go to Settings> General> Reset> Reset Network Settings - helps some people with connectivity issues, but for others it means nothing but the hassle of adding devices and networks back.

    So use this at your own risk. The bottom line is that we are in a chaotic phase at the beginning of an iOS launch where there will be a lot of bugs and fixes and new bugs. It is suspected that iOS 14.0.2 is not too far off, and that it won't be long before iOS 14.1 is released, likely than the iOS version that ships with the new iPhones.

  • watchOS 7.0.3 is supposed to fix reboot bugs in older models

    Just one week after watchOS 7.0.2, Apple is sending another update to its users.

    Apple has released another update for watchOS. However, version 7.0.3 only seems to be intended for one series: the older Series 3 from 2017. Annoying restart bugs had previously been reported for this, which could severely disrupt use.

    Series 4 and newer seem to stick with version 7.0.2, which was released just a week ago. An Apple Watch Series 6 also did not show the update.
    Unexpected reboots and other bugs

    According to Apple, watchOS 7.0.3 fixes bugs and, in addition to correcting the restart bug, contains additional performance improvements. In addition, a "problem is resolved in which the Apple Watch Series 3 unexpectedly restarts for some users". The error could not previously be reproduced in a targeted manner. The restart occurs sporadically, in some cases sporadically throughout the day, in other cases several times within an hour. There did not seem to be any immediate remedy, one of the usual workarounds was to decouple the watch from the iPhone and then re-pair it. The lengthy procedure was able to stop the unwanted restarts - at least temporarily.

    Battery life decimated
    Furthermore, the Series 3 with watchOS 7 is said to have had problems with the battery life - the devices could then be used much shorter than usual. Users also reported that they had to enter new passcodes throughout the day, even though the watch had long been unlocked. According to Apple, watchOS 7.0.2 had explicitly set out to fix a problem "that could empty the battery faster". The company apparently did not address crash problems, which is why the Series 3 needed another update.

    Old watch continues to be sold
    Apple continues to use the Series 3 as an entry-level model in its watch universe. The devices are sold at prices from around 215 euros - in addition to the current standard version Series 6 and the somewhat slimmed-down, but modern version SE. It is therefore important for the group that the Series 3 can still be used.
