How to prevent app falling in sleeping status on Mac?
Solution 1:
You can disable the App Nap feature on any app by finding it in Applications, Get Info, then uncheck App Nap.
The App Nap checkbox doesn't appear for all apps - & I can't figure out what determines that.
Otherwise, you can disable it globally from Terminal using the commanddefaults write NSGlobalDomain NSAppSleepDisabled -bool YES
