Apple releases a 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 have not yet installed the macOS 11.0.1 update.

It’s unclear why Apple 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 Mac M1. Those who have already updated to ‌macOS Big Sur‌ will not see this update, but those coming from Catalina or an earlier version of macOS will receive the new version.

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

New software can be downloaded by opening 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 translation option, in addition to supporting 4K YouTube playback.

Apple has also added updates and new options for messages, photos, and maps, with a list of the main changes available in our feature guide and a full rundown of all available changes in our summary.
