MacBook Pro won't boot into OS after running usually slow
So today for some reason my MacBook Pro (Mid-2012) 13" 8GB RAM/Samsung SSD ran unusually slow when I first powered on.
To the point where it took 1 minute to open Google Chrome later to crash when I tried to enter a URL. I restarted it, and I ran into the same problems, opening up a folder would take ages.
So, I booted into Safe Boot, but to no avail. However, I did look at the System Logs from Console and I took a picture of the logs. For some reason, it was logging an error every 10 seconds since the start of the morning.
I took it to an Apple Authorized repair center at my school who attempted to diagnose it. They attempted to power on my computer but now it wouldn't boot at all.
You could hear the disk drive starting up but you would get stuck at the white screen (no Apple logo, no progress bar). They ruled out the hard drive (esp being that it is only a few months old) after running a few tests on it but they didn't know exactly what was going on, however they did say it could be a corrupt OS.
I haven't had any performance issues prior to today and I didn't install any new software. I'm now stuck with a computer that won't boot and I have finals coming up...
Any ideas? All help is appreciated! Thank you.
