My MacBook Pro wont start up

I was using my MB and out of nowhere the screen froze so I rebooted it and then the pink screen always appears when I try to turn it on also I can't pass the grey screen after the apple logo with the bar, is it a problem with the graphics? Sometimes I manage to boot it up but after a lot of tries and it works normally

Thanks for posting that result.


It looks to me as if your issue is shown under "Disk Information" -- note the "converting" shown on the "encrypted ..." line.


You have somehow set up encryption on your disk. You must be doing some change to/from encryption. This takes resources - and lots of them.


It will pass - it's not a permanent resource hog, but you have to get through this conversion process.
