Introducing Power Protect

In Amphetamine 5.3, a Closed-Display Mode script was introduced to address an issue on Apple Silicon Macs where connecting or disconnecting your Mac laptop from an external power source could cause unexpected session behavior. Running this script required use of Touch ID or an administrator’s password.
Thanks to members of the Amphetamine community (Pitor and Joe), a way to run the script without authentication has been identified and implemented in Amphetamine 5.3.1. To run the script without authentication, you must install both the script and a configuration file. This feature is now known as Power Protect and is only needed/available on Apple Silicon Mac laptops.
