Apple Releases tvOS 12.4.1, watchOS 5.3.1, and a macOS Mojave 10.14.6 Supplemental Update

by

Apple today released tvOS 12.4.1, watchOS 5.3.1, and macOS Mojave 10.14.6 for its Apple TV, Apple Watch, and Mac devices, to go along with an iOS 12.4.1 update that addresses a serious vulnerability.

The new software updates are available immediately on the ‌Apple TV‌, Apple Watch, and Mac.

The three new updates are minor in scale and focus on bug fixes and other under-the-hood performance improvements rather than outward-facing features. On the Mac, the update fixes several issues:

This update:
- Resolves an issue that may cause certain Mac notebooks to shut down during sleep
- Fixes an issue that may degrade performance when working with very large files
- Addresses an issue that may prevent Pages, Keynote, Numbers, iMovie, and GarageBand from updating

tvOS 12.4.1, watchOS 5.3.1, and the new version of macOS 10.14.6 may be some of the last updates that we see before Apple releases new tvOS 13, watchOS 6, and macOS Catalina software this fall.

I haven't seen this many supplementals on the Mac in a long time. Still less than Windows 10 though...
Personally, I think this is a very good thing. I think the reasonable inference to be drawn from more updates is not that there are an abnormally large number of bugs, but rather that Apple is working more proactively to address the inevitable bugs present in complex code as they manifest.

Going from an earlier versions, say 10.14.2 or whatever, would you install the 10.14.6 Combo, then the Aug 1 10.14.6 Supplemental Update and then this August 26 10.14.6 Supplemental Update? Or does this Supplemental Update also include the features in the earlier Supplemental Update?
It appears that Apple released a new 10.14.6 Combo Update today (Aug 26), so I’m guessing it incorporates today’s new Supplemental Update. The previous (Aug 1) 10.14.6 Combo and Supplemental Updates are no longer available from Apple’s web site ('https://support.apple.com/en_US/downloads').

At any rate, after you install today’s Supplemental Udpate, your build number gets updated to 18G95 ('https://support.apple.com/en-us/HT210548'), so if that’s your build number ('https://support.apple.com/en-us/HT201260') after installing the Combo Update, then you should be up to date.

This is the second supplemental update doe 10.14.6, that addresses assimilate sleep issue that was introduced in the original update. They really should fix versioning and call it 10.14.6.2, or 10.14.8.

My late 2013 MacBook Pro has been restarting during sleep, and no joke, I had started shopping for new Macs. Glad to see this was an issue that they addressed.

next time - WAIT, it should be fine. be patient
I agree that waiting is a good idea. You really don’t want to tempt fate by relying completely on an abortive update sorting itself out completely in the event of an interruption. On Windows they say Do Not Turn Off Your Computer, for this reason.

But I would say there’s a general problem with Apple’s update UI. If things look stuck, customers will naturally assume that it has stuck. Personally, I’d like to see more detail than a line crawling (or not crawling) across the page. Worse of the worse is where you get the line starting again from the beginning for no good reason. That doesn’t even look slick. It looks like something is messed up. More information = good.

So you're saying the difference between OS X 9 and OS X 10.0 is more significant than the one between OS X 10 and macOS 12?
If by macOS 12 you mean macOS 10.12 and by OS X 9 you mean Mac OS 9: yes, absolutely it is. System 1 through Mac OS 9 were basically a completely different OS than Mac OS X 10.0 through macOS 10.15 are. The latter is an evolution of the NeXTSTEP operating system, with Mac additions (such as QuickTime, AppleScript, Carbon, …) sprinkled in. (iOS, watchOS, etc. are all descendants of that, in turn.)

10.0 was a very big change and no iterative change since has been quite as big (nor would that be necessary).
