Chosen Solution
I have two MacBook Pro’s, one that I use and one that my partner uses. Late last week my partners Mac stop booting up, it would allow her to get to the login screen but when she put her password in the bar would only go around 50/60% of the way up and then stop. I hadn’t had chance to look into this properly yet, however yesterday I was watch a video on my Mac and it suddenly cut out completely (no power at all). When I turned my Mac back on I’m having the same issues as my partner. Both of the Macs are exactly the same model and bought within a few days of each other. So far I have…
- Reset the SMC
- Reset the PRAM
- Reinstalled the operating system -Used first aid on the HD from disk utility Anyone have any further suggestions? Its strange both Macs got the same issue days apart.
I would try booting up in safe mode to see if that worked. If it does then you have a software level issue. If not you’ll need to look at booting up under an external drive if that worked your issue is the HD SATA cable needs replacing. If not your logic board has a problem. Here’s the IFIXIT guide to replace the cable: MacBook Pro 13" Unibody Mid 2012 Hard Drive Cable Replacement and here’s the part: MacBook Pro 13" Unibody (Mid 2012) Hard Drive Cable. I apply a layer of electricians tape on the uppercase where the cable rests as the metal case tends to damage the cable.
