MBP won't boot...pls help [VIDEO]
Hi, I'm having serious troubles to figure out what's wrong with a mid-2012 13" MBP.
Basically upon turning it on, it shuts down a bit short after the progress bar with the apple logo appears. Pls refer to this video:
I've tried all this and always see the same behaviour:
- Resetting PRAM & SMC
- Swapping RAM with that of another working Macbook
- Swaping the hard drive with that of another working laptop
- Booting in safe mode (command S)
- Booting with a USB drive with a bootable image of OS Sierra
I ran the onboard diagnostics (command D) and came up with no hardware errors.
I don't know what else to try.
Input greatly appreciated...
