If Amphetamine is not working as expected, is freezing, etc. the first step to resolving the issue is to confirm whether the issue persists under a new user or guest user account.

How to test an issue in another user account on your Mac


If you confirm that indeed the issue is isolated to your user account, the next step is to figure out what is causing the issue in your user account.

Minimal System

To help further isolate the issue, try connecting the bare minimum of devices and peripherals to your Mac. Disconnect USB devices, displays, and Bluetooth devices. Quit other apps that are running. You may find that a particular connected device interacting with Amphetamine is causing the issue, or perhaps another app interacting with Amphetamine is (e.g. anti-virus, etc.).
