macOS Big Sur 11.2 RC 3 could affect security vulnerabilities
It’s unclear what prompted Apple to distribute a third pre-release version of the upcoming update. One possibility, however, is that this modified RC is related to a vulnerability that was recently discovered in the sudo command. This command can be used to execute code with maximum privileges on Unix-like operating systems. Patches for various Linux variants had been released in the last few days. It is not clear when macOS Big Sur 11.
2 will be released for all users, but it should be at least next week.
macOS Big Sur 11.2 brings various improvements and bug fixes, including those related to Bluetooth and external displays.
