Apple Releases macOS 10.13.6, iOS 11.4.1, tvOS 11.4.1, and watchOS 4.3.2

Apple has released macOS 10.13.6, iOS 11.4.1, tvOS 11.4.1, and watchOS 4.3.2. Apart from the addition of AirPlay 2 support in macOS 10.13.6 High Sierra, all the releases focus on minor bug fixes and blocking security vulnerabilities.

macOS 10.13.6

A few hours after releasing the other updates, Apple pulled the curtains back on macOS 10.13.6, which finally brings full AirPlay 2 support to the Mac in conjunction with iTunes 12.8, joining iOS and tvOS (see “iOS 11.4, tvOS 11.4, HomePod 11.4, and watchOS 4.3.1 Finally Debut AirPlay 2 and Messages in iCloud,” 29 May 2018). We don’t have details yet (the update isn’t even showing for all of us), but Apple says that you’ll be able to use your Mac to control your AirPlay 2 speakers and play the same music on multiple AirPlay 2 speakers simultaneously.

macOS 10.13.6 also fixes a problem Photos had in recognizing AVCHD media from some cameras and a bug that could prevent Mail users from moving a message from Gmail to another account.

macOS 10.13.6 release notes

As always, the update includes a variety of security fixes throughout the operating system, addressing 11 separate vulnerabilities.

iOS 11.4.1

The iOS 11.4.1 update fixes an issue that prevented some users from viewing their AirPods’ location in Find My iPhone and improves the reliability of syncing mail, contacts, and notes with Exchange accounts. It weighs in at 190.6 MB on the 10.5-inch iPad Pro and 225.2 MB on the iPhone X, and you can obtain it in Settings > General > Software Update or install it through iTunes.

iOS 11.4.1 release notes.
iOS 11.4.1 also apparently includes the new USB Restricted Mode, which makes iOS devices harder to crack. Apple has been hinting at this functionality in betas for a while, most recently in the betas of iOS 11.4 (see “iOS 11.4 to Make iPhones Harder to Crack,” 10 May 2018), though it did not arrive with iOS 11.4.

The iOS 11.4.1 update features 15 security fixes.

tvOS 11.4.1

The tvOS 11.4.1 update merely offers “general performance and stability improvements.” If automatic updates aren’t on, you can update your fourth-generation Apple TV or Apple TV 4K by going to Settings > System > Software Updates.

tvOS 11.4.1 includes 11 security fixes.

watchOS 4.3.2

Similarly, watchOS 4.3.2 just “includes improvements and bug fixes.” You can install the 54 MB watchOS 4.3.2 update using the Watch app on your iPhone (in Watch > General > Software Update).

watchOS 4.3.2 release notes.

As always, we recommend waiting a few days to install these updates unless you want to get started with AirPlay 2 on your mac, expect to need Find My iPhone to locate your AirPods, or are having trouble with Exchange syncing on your iPhone or iPad.

watchOS 4.3.2 includes 11 security fixes.

Comments About Apple Releases macOS 10.13.6, iOS 11.4.1, tvOS 11.4.1, and watchOS 4.3.2

Notable Replies

  1. They’ve already added a setting for requiring TouchID before USB data transfer. :+1:

  2. It will be a few days before I can update High Sierra. I hope it will support stereo Homepods. It is embarassing that a humble iPhone can play to them but not my Mac.

  3. Apple also released a HomePod update (to 11.4.1). I own 2 HomePods set up as a stereo pair which work fine on IOS but until now have not been identified as a pair from my Macs.

    I haven’t yet upgraded my iMac to the latest High Sierra release, but my MacBook Pro, running the latest public Mojave beta now shows the stereo pair in iTunes. However, the system volume controls still show two separate speakers as does the Airfoil app. I have verified that iTunes does, in fact, produce stereo output, bu tthe system output only goes to the named speaker.

  4. Does anyone know if this latest release resolved the issue that prohibits the use of external mo Igor’s because of a Datalync issue? That started with the previous release.

  5. I’ve now updated my iMac to 10.13.6. Stereo HomePod works the same here as in the Mojave Beta (works for iTunes but not for System Output).

  6. Sorry about the typing error. I was talking about an external monitor. With the Datalync problem external monitors that use Datalync won’t work unless Apple has fixed it. I won’t upgrade to the latest version of MAC OS until it is fixed because I don’t want to lose the use of my 23 inch monitor attached to my laptop.

  7. What is “Datalync?” My searches haven’t found anything relevant.

    FYI, you can edit your comments in the Discourse web interface, there’s a pencil icon to “edit this post.”

  8. I can’t find it either. Assuming there is some sort of driver software involved, can you provide a link to that, as well?


  9. If that’s the problem, then it was determined that DisplayLink would need to solve the problem, not Apple, so you won’t find that macOS 10.13.6 will fix it.

    I know that DisplayLink had a beta out that seemed to fix some, but not all situations and there were reports of workarounds, but don’t know whether that was for all issues or not.


  10. Hi Josh, Does anybody know yet whether MacOS High Sierra 10.13.6 fixes the 2012 iMac Sleep problem? We’ve been waiting for that fix for some time now.

  11. Sorry, I have no idea.

  12. Works well. If you want to test the stereo Hompods try listening to Let It Be Naked. Feels like I am sitting in the Abbey Road studio!

    Update: Previously the Apple TV could not use the stereo Homepods for playing video via the Computers app (it reverted to default audio - a hifi). Now it does play to the Homepods but they are hopelessly out of sync.

    Grrr! Sending feedback to Apple.

    Updated update…
    Just tried playing the same movie directly from iTunes on the Mac and the sound via stereo Homepods was good (in sync and in lip-sync). So the problem is only occuring when using the Computers app on the Apple TV. It does concern me that Apple seems to be neglecting this app, which could go the way of Front Row as it doesn’t suit their business model of streaming content.

  13. That’s quite a collection. Appear to be more than one type of behavior involved, although most sound like kernel panics. Also seem to be a few other Mac models reporting similar issues.

    Since my iMac is a mid-2011, it may not be pertinent to this discussion, but in looking back I see the first time I reported an unexpected reboot after sleep was with 10.13.1 on Oct 10 and again on Oct 13.

    Then there was a Kernel Panic involving 10.13.4 on Feb 18.

    My habit back in those days was to press Command-Option-Eject to put the iMac to sleep at night and press the space bar to wake. My workaround to avoid those issues was to simply invoke the screen-saver when retiring and letting the computer decide when to sleep the screen and the computer.

    After installing 10.13.6 I’ve gone back to using Command-Option-Eject just to see if any of those issues are still there. So far, so good.
