Why is my Mac turning itself off after going to sleep?

Episode 990 (1:07:48)

Charlene from Gilbert, AZ
Apple iMac

Charlene has an iMac, and when she tries to wake the Mac from sleep, she has to reboot it instead. Leo says that there is a setting for it to turn itself on after a reboot, so she should try enabling that. She should also use a universal power supply that can protect the computer in the event of a power spike or reboot.

Leo also says it's best to be running the most recent version of the Mac OS. Upgrades are pretty cheap with Apple at $29.99, and it's easy to install. She'll just go to the Apple Mac App Store, buy the update and download the installer. Leo then recommends copying the installer before she runs it, just in case. Then run it and update her system.
