Open a terminal and type either :

Warning

Ensure that Snooz has full disk access to launch it from the Launchpad by following these steps:

  1. Open System Settings.

If Snooz does not have full disk access, it may hang when loading a file chosen via the Snooz interface. Launching Snooz from the terminal provides broader disk access than the Launchpad, so using the terminal is recommended if you prefer not to change the settings.
