Hi, I updated my MacPro with OS X 10.10.3 Supplemental Update and my the computer restarts when shutting down. I have to cut the power strip to keep it off.
Does anyone know of a fix for this?
MacBook Pro, OS X Yosemite (10.10.3)
Try starting in Safe Mode
OS X: What is Safe Boot, Safe Mode?
Try starting in Recovery mode and repairing the startup disk
OS X: About OS X Recovery - Apple Support
Reinstall Yosemite

Thanks, if I re-install OS X 10.10.3 Will it erase my HD? Also I've never used Time Machine.
Using the reinstall link I provided nothing should be lost.
However,you never know what will happens since yo were having problems
10.10.3 keeps restarting
