Apple today released macOS Big Sur 11.2, the second major update to the macOS Big Sur operating system that launched in November. macOS Big Sur 11.2 comes more than a month after the release of macOS Big Sur 11.1.


The new ‌‌macOS Big Sur‌ 11.2‌ update can be downloaded for free on all eligible Macs using the Software Update section of System Preferences.

According to Apple's release notes, macOS Big Sur 11.2 addresses several bugs, such as an issue that could cause external external displays to show a black screen when connected to an ‌M1‌ ‌Mac mini‌ using an HDMI to DVI converter and a problem that caused iCloud Drive to disable when turning off the iCloud Drive Desktop & Documents Folders option.

Apple's full release notes for the update are available below:
macOS Big Sur 11.2 improves Bluetooth reliability and fixes the following issues:
- External displays may show a black screen when connected to a Mac mini (M1, 2020) using an HDMI to DVI converter
- Edits to Apple ProRAW photos in the Photos app may not save
- iCloud Drive could turn off after disabling the iCloud Drive Desktop & Documents Folders option
- System Preferences may not unlock when entering your administrator password
- Globe key may not display the Emoji & Symbols pane when pressed
Though not mentioned in the release notes, one of the macOS Big Sur 11.2 betas removed a feature that allowed Apple apps bypass third-party firewalls, security tools, and VPN apps. ‌macOS Big Sur‌ 11 included a ContentFilterExclusionList that let Apple's apps like the App Store, Maps, iCloud, and more to avoid firewall and VPN apps that users had installed.

These apps were not able to filter or inspect traffic for some built-in Apple apps, and the functionality has been removed. Apple apps will now be compatible with VPN apps and will no longer be able to bypass firewalls and other security tools.

‌macOS Big Sur‌ is a major update that brings a full redesign to the Mac, along with new features designed for ‌M1‌ Macs. Complete details on all of the new functionality in ‌macOS Big Sur‌ can be found in our roundup.

And now I update (from RC2 11.2)

FYI- bluetooth appears to be fixed. Went two days without a disconnect, even some time at a BT congested coffee shop with it.

Would've cut in and out about 15-20x in that timeframe, on 11.0.1 previously on my M1 air.

RC3 build = GM. 20D64 is build number for both.

This is downloading on my 2017 iMac, but it isn't showing up yet on my 2019 MacBook Pro.

I am hoping that they finally fix an annoying bug with Sidecar. When I am using Sidecar, all video that is playing just shows up as a black window. Has anyone else seen this?

I just hope it gets rid of that annoying little black square in either of the top corner of the screen.

What's with the numbering system? It makes it look like there's been 2 significant OS updates since Big Sur came out, when the truth is there's been 2 bugfix releases. What's wrong with calling it 11.0.2?
They are just aligning macOS version numbering to match iOS, iPadOS and tvOS. This year, I bet that macOS will move to version 12 to indicate major release, just like the rest will move to 15.

I miss the days of seeing these notices and seeing an update available. Still not available here. Restarting, closing settings doesn't seem to help. (Yeah I don't HAVE to have it now but...) lol.
