Apple today seeded a third RC version of an upcoming macOS Big Sur 11.2 update to developers for testing purposes, with the new update coming a week after the second RC and more than two months after initial macOS Big Sur release.

Developers can download the updated ‌‌macOS Big Sur‌‌ 11.2 release candidate using the Software Update mechanism in System Preferences after installing the proper profile from the Apple Developer Center.

macOS Big Sur 11.2 eliminates 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. That functionality has been removed in macOS Big Sur 11.2.

When macOS Big Sur 11.2 sees a release, Apple apps will be compatible with VPN apps and will no longer be able to bypass firewalls and other security tools.

According to Apple's release notes, the update also improves Bluetooth reliability and includes multiple bug fixes.
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

The update addresses a bug that could cause external displays to show a black screen when connected to an M1 Mac mini using an HDMI to DVI converter, and it fixes an issue that resulted in edits to Apple ProRaw photos in the Photos app not to save. It also includes fixes for iCloud Drive, System Preferences, and more.

Update: There was speculation that today's update may address a sudo vulnerability that could allow a local user to gain root privileges on macOS, but it does not appear that the vulnerability has been addressed.

Where’s the final release 🥺

Noticed my M1 MacBook Pro once logged in takes a few extra seconds to become responsive, get the occasionally beach ball for a second then goes away, hopefully 11.2 gets rid of it.

"Apple today seeded a third RC version"

Three seems… unusual (unprecedented?) for Apple OS releases.

So were the first two RCs essentially more beta versions? Why call them RCs?

Well, the difference between a beta and an RC is that an RC is intended to be identical to the final release if all goes well, whereas a beta is known to have issues that shall be fixed until final.

They're clearly running into some last-minute stuff.

RC1, RC2... M1 Air...

try RC3 or wait a few days, hmmm

my experience has been good on this one

what's the build number of this one ?
 
  • Wow

As usual, there will also be a Supplemental Update (With Initial Caps) a few days after the Release Candidate turns into Release Version, indicating that it is really Beta Software that hasn't gone through Quality Assurance. Turns out that one can escalate to Root Privileges by displaying a new emoji in Safari, and therefore you have to download the entire package of 138.6 GB again to mitigate the problem.

Sudo vulnerability should not affect Mac OS as sudoedit is not available on Mac.
Click to expand...

sudoedit in Linux is just a symbolic link/alias to sudo.

Code: 
$ ls -lsa /usr/bin/sudoedit
0 lrwxrwxrwx 1 root root 4 Jan 26 18:34 /usr/bin/sudoedit -> sudo*

The vulnerability is in sudo, the version that ships with MacOS should be vulnerable and following the steps in the disclosure seems to indicate so.
