Apple issues third macOS Big Sur 11.2 RC to developers and public beta testers

The latest RC arrives just three days after a second version was issued on Monday and six days following an initial RC build last week.

Developers can download the most recent Big Sur release from Apple's Developer Center or as an over-the-air update. A public beta versions is available for download from the Apple Beta Software Program website.

The macOS Big Sur update appears aimed mainly at introducing under-the-hood improvements and bug fixes. A significant change is the striking of a controversial "exclusion list" that allowed Apple apps and processes to bypass firewalls.

According to the release notes, the update includes fixes for 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

Both AppleInsider and Apple strongly suggest users avoid installing betas on to "mission-critical" or primary devices, due to the potential for data loss or other issues. Instead, the recommendation is to install betas onto secondary or non-essential devices and ensure sufficient backups of important data before making any major changes.
