My 2008 mac pro in my signature decided not to wake.
Mac mini power light pulsing.

Probably 10 6 x uncertain when it was answered by a verified mac support specialist.
When it happens like that the power on and of too won t work unless i switch the main socket off.
If the issue persists press and hold the power button on your mac for 10 seconds then try starting up from macos recovery if that works continue to the next step.
Mac mini but after a while it won t boot at all.
Specs are dual core i5 2 5ghz 8gb ram 1tb hd.
Now restart the mac.
So after a smc reset the mac pro would not fully start and gave me the dreaded 3 blinking power light.
The power light is displaying all right but everything else is not working can hard disk board etc everything is not working.
Only the power light is on.
Well it just hit me.
Check your mac turns on.
