Mac Mini wouldn’t power on after a recent update. No light or fan with power button. Replaced power supply, no luck. Of course out of warranty. Not sure what to try next.
Hi. Check this iFixit posting: Does not turn on Your device should still be under warranty. If it’s not it should only be out of warranty for a few months and you should be able to request an exception from Apple. Let me know how you get on.
