My macbook pro mid 2012 has a horizontal pixel line. It appeared after an actualization. Do you think it could be a matter of the display or software? Thank you
Actualization? What does that mean in this context?
Oh, accident. Most likely a hardware issue with the LCD itself.
This is not a difficult procedure. It takes about 10 minutes, half that if you know what you're doing, maybe twice that if you don't have a clue.
so I did the dc port succesfully because it started, but now it starting up immediately to a white screen and has a loud fan noise, Also the magsafe light stays off. but i need the files and pgp keys on this mac, now, i have a workstation,iMac, if i were to use target disk mode, would they know that i did this at Apple?and if there is a chace of a kernal panic ?woud have to send my work station in. no time machine back i know ... Please dont lecture me. So far i did a nvram reset while it was on the white scren some how it just boots back to white screen. when i do s tandard smc reset it doesnt boot at all. when i do a nvram on the white screen it just resets itsef. cannot get nto recovery becasue its just a white screen. I also do various other ways of smc resets, but it llways boots to white scren, is this dsplay? do i have to replace the dispaly as per guide? what's happening,any ideas?
