Apple today released a revised version of macOS 11.0.1 Big Sur, which appears to be available for some Mac users who had not previously installed the macOS 11.0.1 update.


It's not clear why Apple has released a new version of macOS Big Sur 11.0.1, but 11.0.1 is the launch version of Big Sur on all Macs except for M1 Macs. Those who have already updated to macOS Big Sur will not see this update, but those who are coming from Catalina or an earlier version of macOS will get the new release.

Today's update comes a little over a week after Apple first released macOS 11.0.1 Big Sur. The new version has a build number of 20B50, while the prior version had a build number of 20B29.

The new software can be downloaded by opening up System Preferences and choosing the Software Update option.

‌macOS Big Sur‌ is a major update that brings a redesigned look to the Mac with Control Center, new widget options. Safari is faster and more battery efficient and there are new privacy protections and a translate option, plus it supports 4K YouTube playback.

Apple has also added updates and new options for Messages, Photos, and Maps, with a list of the major changes available in our features guide and a complete rundown of all the changes available in our roundup.

I’m hoping VPN is stable now.

I’ve been having intermittent OpenVPN connectivity issues where the connection sporadically drops, and it’s getting in the way of remotely backing up my family NAS - 6TB worth of data left.

Unfortunately, no way to get it if already on Big Sur. Could try downloading from App Store, but that version says it's a week old in version history.

I wonder if they are back-porting some of the critical fixes in 11.1 (Thunderbolt, SMB) into 11.0.1 for folks who have not yet upgraded (which doesn't help folks like me who have and are experiencing both issues).

probably have to wait till 11.1 is released in December for those of us who are on 11.0.1 already.

That's the first time I'm seeing a background photo as opposed to the abstract image. That's what I would want on mine.

I’m probably very late to ask for clarification on this question but: wasn’t El Capitan the “11.0” version of OS X / macOS? So Big Sur should be 16.0? What happened to the old numbering system?!
