Make sure to be protected, do a second reboot after the update!
Apple released the macOS Big Sur update 11.3 on April 28, 2021. If Sophos is installed on an M1 (ARM) based system prior to the update, the first time the system boots after the update, protection will be compromised. Restarting the system again resolves this issue.
The issue can be observed when the following conditions are met:
1. macOS 11 had Sophos installed prior to updating to 11.3
2. Upgrading to macOS 11.3
3. M1 chip (ARM) based hardware only (Intel hardware is not impacted)
4. This also applies to the 10.1.0 M1 (ARM) Optimized EAP.
Systems that are not impacted by this:
1. Systems with Intel chip macs
2. New Sophos installs on macOS 11.3
3. Systems with macOS 10.15.7 Catalina and below
Resolution:
Restart the computer once again after upgrading to macOS 11.3!
