Reading posts here and on Discord, the theme with 14.1 Beta is fairly clear... do your 14.1 Beta testing in a Volume that you can afford to lose and be prepared to bork your 14.1 install if you apply OCLP post-install patches. Most reports I see show that 14.1 Beta "works" until post-install patches are applied. Do yourself a favor and don't test 14.1 with post-install patches unless you're prepared to re-install.
EDIT: Depending on your SMBIOS model, without post-install patches, 14.1 will operate without graphics acceleration and without Wi-Fi.
Is there anyway to uninstall the post-install patches on a volume different to the one the system is running ?
