This is on an M1 MacBook Pro running 11.1b1. I installed an Extension from Rogue Amoeba to support their App Suite. Boot into recovery to set system policy to allow user permission of extensions Reboot and install extension Allow Extension in Preferences > Security panel Allow rebuild and restart. It comes up with an endless loop of failure due to an Extension from Apple Inc. ! The Rogue Amoeba extension loads fine. Any ideas?
