If necessity is the mother of invention then we have a reason for Hypnotize, the clever and free way to set a timer to shut down your Mac.
Uh oh. This might be a very short app review.
Hypnotize resides in the Dock and has a standard array of shutdown minutes, starting with 15-minutes, going up to an hour, but the intervals are customizable. What happens is this. Click on Hypnotize, select the desired shutdown interval from the pop up, and go about your business until the warning arrives telling you your Mac is about to shutdown.
What happens if the shutdown time interval needs to be extended? Click Hypnotize and select another time.
Yes, your Mac has an auto shutdown feature in System Preferences > Energy Saver > Schedule but using that function simply to shut down your Mac at a set time is cumbersome at best, and needs to be reset when the Mac starts up again.
That makes Hypnotize a perfect companion for anyone who needs the Mac to stay running for a few more minutes– while files are downloading, or a backup is taking place– but when you don’t want to sit and watch the process.
Unfortunately, if you have a running app with an unsaved document Hypnotize won’t save it for you, and then shutdown, but it won’t delete the unsaved document, either. It just sits there waiting for you to fix the problem. I’d pay a few dollars if it could auto save documents, then close apps, then shutdown according to the timer.
But, hey, it’s free and it works well.
