Have looked for a way to disable the desktop banner alerts w/o any luck. If this is not possible in Parallels Toolbox, I would like to request that function to be added. Going to MacOS's System Preferences -> Notifications and deselecting all checkboxes for Parallels does not stop the banner alerts as it should. Bug perhaps?
Hello, To disable notifications from Parallels Toolbox tools you should deselect checkboxes not for Parallels Toolbox program but for every tool separately. For example to disable notifications from 'Do Not Sleep' tool find 'Do Not Sleep' program in the left pane of 'System Preferences -> Notifications' and deselect appropriate checkboxes.
