    My iMac pro was taking itā€™s sweet time waking up with a keyboard press then logging in with my Apple watch. Just did the SMC reset. Now it is almost instant! Went from 10 to 15 seconds to zero. Glad I read the list of symptoms this can fix.

    I can'y thank you enoughfor your help in managing my Macs. When people in my office saw me do these things and how eforlessly they solved their problems they thought I was a wizard. I kept giving them your url hoping they'd be able to learn to tap your endless resources. One did and soon she got a better job.
