Hi guys,

My late 2013 27" i5, used to wake up in a couple of seconds, but I just installed High Sierra (from Sierra), and now it takes like 10 seconds to light-up the screen. What can this be?

thanks for your help
 
Oh, and it now wakes up with a different screen brightness every time...????
 
 
Found the perfect solution - Back to Sierra, so long High Sierra!!!!!! :p
