[waynepixel]

I have just up-graded to 10.3.7 and for some reason my Studio Display 17-Inch will not wake from sleep anymore.


Anyone here had this problem. Any idea as to how I might thicks the problem please.

Pretty common problem.

Reboot Mac and hold down Command-Option-O-F until you see command line. Type the following, press return after each command

reset-nvram
set-defaults
reset-all

Mac will then reboot. If that doesn't work, try deleting the com.apple.powermanagement.plist file.
