MacRest
Let your Mac actually sleep.
MacRest runs in the background and catches any apps attempting to block sleep, and asks you for permission to block sleep.
A lot of apps quietly block system sleep, often for no real reason. macOS lets any app silently prevent sleep, and there's no proper built-in way to see which one is doing it or to stop it.
The first time an app tries to keep your Mac awake, you get a small notification to allow or block the app from preventing system sleep.
From the settings, you can define apps that will always keep the system awake, choose which ones should never be able to prevent sleep, set custom sleep delays for power and on battery, and choose what system actions should prevent sleeping.
