I don't recall any update in the last few days, but now my mac mini will not wake up from hitting the space bar, return key or the mouse. It only wakes up through the power button.
Hi, just wondering, in Sys Prefs>Energy Saver>Options tab, is allow power button checked?
Some things to try...
Have you done a PRAM reset, CMD+Option+p+r...

Mine did the same thing. Just unplugged all for about 30 seconds. Plug all back in and all OK.
Now that I think back, we had a short power failure the day that this happened. It didn't last but a couple of seconds, but it was enough to zero out the microwave clock.
why won't mac wake up by keyboard or mouse command? this just started.
