lastly wait for the mac to enter sleep mode itself (check energy saver and set the timer to standard settings or some timing that is realistic for your patience).On newer macs i am not sure how to check if it sleeps, other than listening for the fans to stop spin. On my mac i can check that the led starts to “breathe” when it sleeps. wait for the sleep to initiate! It can take quite some time (maybe over 1min).

once you a logged in you can start by initiating sleep mode by pressing alt + cmd + eject (or power button on newer macs).

Turn on again and enter safe boot (hold down “left shift” on bootup until you see apple logo).

I noticed when in safe boot i was able to make the mac go to sleep without it shutting down, and by initiating the sleep mode through 3 possible ways it sort of “learned” and when booting up into my normal user account i had no issue anymore. The newsest methood is by far the easiest! I have now solved it the same way i have solved issues with the computer not shutting down when initiating a shutdown.

In System Preferences, open Network preferences.Ģ. This occurred after sleep whether by lid closing or software command.ġ. would display a message something like, 'A kernel panic has occurred and the only thing you can do is hold down the power button until the machine shut off.'
