I can concur that substituting a SSD will not void your Apple Care warranty. In comparison to the latest and best Apple has to offer it holds up well, and surpasses all in ease and ability to upgrade components. Hence why I wonder if it's hardware related, although it does seem the screen does (sometimes) work.The Mid 2012 cMBP is a good solid computer with a beautiful screen, even if not retina. I had hoped I could just install a new OS with an external USB installer but alas not. The machine had not been making a chime on boot up, and I did manage to do a NVRAM reset and it now chimes, however it just goes black.Īctually, I say I did the above things, but 90% of the time it just powers up and the screen is black. It behaves normally, I select the installer and then it goes black (and again I have to hold down the power button to turn it off). * I try the select startup disk in order to clean install from a USB drive installer of Catalina. The machine still hums quietly and I have to hold down the power button to turn it off. it was a black background before, but now it is black as in the power is cut to the display). When I do try it either stays black, or the white apple w/ progress bar appears on the black screen, then at around 75% the screen goes black (ie. I've not been able to get it back into Recovery Mode since this one time. * I try to boot into recovery mode, this has only succeeded once and trying to erase the machine, I got this message: The machine then goes black (and I have to hold down the power button to turn it off. I select my account (the only one) and enter my password, everything looks ship-shape. * 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.
