Apple Releases Revised Version of macOS 11.0.1 Big Sur

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.

First Look Big Sur Feature2
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.

how can we get it if we already have Big Sur
Simply uninstall Big Sur, and go back to Catalina. Then just go back to Big Sur. Easy! ;)

Apple's quality control division probably having an aneurysm. The point of "releasing" something is that it can't be "unreleased" and replaced - or at least certainly not with the same revision number. Then again, Apple does what Apple wants.

Why isn't this just released as 11.0.2?

That's a lot of work for a version that probably brings no operationally-related fixes. I would guess this was released to resolve the installation problems encountered with original 11.0.1.

Perhaps this is a fix for the installer/upgrade process, hence why its not needed for those already on Big Sur.

Maybe it fixes that issue with the factory recovery issue you reported on the other day.
