MacBook Pro Won't Boot Up and Stuck at 50%, What To Do?

Alright so I have Yosemite 10.0.0 OS X & MacBook froze up on me today so I manually restarted it by holding down the power button. I waited about 30 seconds then pressed the power button and it turned on, but when I turned it back on the brightness w down very low and it brought me to the Safe Mode/ boot screen that Yosemite bring you too, well it stopped booting up at about 50% so I figure if I leave it plugged in and go do something it'll finish booting up because I thought it was just being slow, well 6 hours later and I come home to a dim screen & it's still on the same screen & still at 50%, does anybody know how to fix this?

Hi there, the trouble that MacBook Pro won't boot up and gets stuck at 50% seems quite normal since it befalls so many people as well. For the Mac computer that freezes on startup, you should first check if you have a backup of your data to avoid permanent data loss. If not, iBoysoft Data Recovery for Mac will be a good helper to recover lost data when the Mac is stuck on the loading screen.

Hello everyone, I was wondering if I could factory reset an old MacBook 2007 A1181 without an Apple ID. Because I was given it by a coworker who also does not have a password. Thanks in advance.
