By default, keeping AMPLL up-to-date requires no manual intervention. AMPLL checks for updates periodically, and it downloads and prepares those updates in the background.
You can prompt AMPLL to check for updates immediately by choosing Check for Updates from the Help menu.
Checking for updates from the AMPLL Help menu
To apply updates, AMPLL needs to restart. By default, AMPLL restarts automatically when the Dashboard is closed and it does not detect you are in an ongoing video call.
You can choose to Disable auto restart on update from the Help menu. When auto restart is disabled, AMPLL typically presents a notification to restart. Clicking the notification typically restarts AMPLL to install the update.
AMPLL update notification
If you ignore or do not receive the notification, you must quit and restart AMPLL from your Applications folder.
