macOS 11.2.1

Juli Clover:

According to Apple’s release notes, macOS Big Sur 11.2.1 addresses an issue that could prevent the battery from charging in some 2016 and 2017 MacBook Pro models.

Juli Clover:

According to an Apple security support document, the bug, CVE-2021-3156, was addressed in the update by updating to sudo version 1.9.5p2. Apple has also fixed the bug in Supplemental Updates made available for macOS Catalina 10.15.7 and macOS Mojave 10.14.6.

Mr. Macintosh:

A Full Installer of MacOS Big Sur 11.2.1 is not available yet.

Neither is a downloadable update or combo update.

An interesting Big Sur “feature” I have noticed is that virtual machines — at least those run by Parallels — never pick up on any updates: neither System Preferences nor the command line ever offer updates. The only solution is to download a brand-new installer from a Catalina machine, to copy it to all virtual machines, and to use it there, where it will place the machines into a “post-install” state requiring a run through Setup Assistant. Truly the stuff of nightmares.

Howard Oakley reports that the update is 4.2 GB for M1 Macs. The counterpart patch for 10.15.7 is 1.34 GB.

For a small security patch?

Absolutely absurd.

Came here to make the same comment as Ben Kennedy, although the patch on my M1 MacBook was ~3.5 GB. I miss the days when delta updates were <100 MB!

I have a 5 MBit/s internet connection at home, and I know a lot of people on crappy sub megabit DSL here in WA, once you get away from major cities. Just as Apple started assuming I/O is cheap because of SSDs (and murdered performance on iMacs/laptops with spinning disks), it now assumes that everyone can download massive updates to the Mac. Unfortunately, it's done so while removing the ability to download a combo updater elsewhere and apply it to multiple systems at home.

@F. - Yes, I've noticed the same with Big Sur VMware Fusion, except that one can download the full installer in a Big Sur VM by searching for "macOS Big Sur" in the App Store and initiating the download from there.

Unfortunately, there doesn't seem to be an 11.2.1 installer yet (not sure there ever will be one). Even if there were such a beast, it certainly is unsatisfactory to have to download a 12+ GB installer for what otherwise should be a relatively small update.

Doesn't Content Caching still work for this?

@Sören - Sort of, kind of, but not entirely. Howard Oakley posted a very interesting article about this subject today: Big Sur, Software Update, Content Caching Server and M1 Macs

So, on the one hand, we have Apple overengineering a Merkle Tree-based concept of "sealed system volumes".

OTOH, who even needs digital signatures when downloading development dependencies from the Internet, right? YOLO. https://twitter.com/hmemcpy/status/1359478493386592267

Maybe a middle ground would've been nice.
