* I power on the machine and it does get to the user selection window. The screen is blank/black and I have to hold down the power button to turn it off. * I power the machine on and it makes very little noise, I have to put my ear to the keyboard to actually hear it is on. I get slightly different results but generally. FYI it's always plugged into the power brick, as the battery life is pretty terrible. Since then I've not successfully been able to restart the machine. Then this week the machine just turned off.


I restarted the machine and it seemed OK - I never got the option to review the kernel extensions and forgot about it. I have a MacBook Pro Retina 2012 (first generation of the retina MBs) running 10.15.7 Catalina.įrom memory I hadn't been fussing around with the machine (installing new software etc.) Hi everyone, I've tried searching for help on this problem, but I can't get any satisfaction.
