How to roll back from macOS 12 beta to macOS Big Sur

To begin with, it is worth noting a couple of nuances. If you backed up your system before installing the beta, you could restore your data from a copy of Time Machine.

To roll back, you need to format the disk on which the beta version is installed. If you installed macOS 12 beta on a disk partition, you could simply delete it, and your Mac will boot macOS Big Sur.

It is better to prepare the macOS Big Sur installer on a flash drive in advance. Once again, we note that this instruction is relevant for those who made a “clean installation” of macOS 12 beta.

1) In the menu bar, click the Apple logo and select Restart.

2) Press the Command + R keys until the Utility menu appears.

3) Select Secure Boot Utility, enter your password and enable the Allow download from external media option.

Restart your computer again and repeat Step 2 to open the utility menu.

1) Select Disk Utility, click Continue, and select your startup disk (most likely Macintosh HD).

2) Click Erase at the top of the page and select your format. Enter a new name for the disc or leave the Macintosh HD. On new Macs APFS format, and old ones – HFS+(journaled).
