It wasn't like this before. Somehow, if I leave my USB plugged in, my Mac doesn't boot. Instead it gets stuck at the Apple logo with a very slow progress bar. When the bar finishes, it just waits. I tried resetting the PRAM but nothing changed. I also tried booting into Safe Mode, but it wouldn't boot. I did boot into Recovery Mode (cmd + r), and was able to repair the disk, but it said everything was fine. But I still can't boot my Mac. What should i do?

PS: I dont know why, but there is a Disk named Mac OS X Base System in Recovery Disk Utility, which I only see when I can't boot my Mac. I also can't eject this.

  • Can you boot off single user mode that holding cmd+S at start-up chime and do you have a backup of your data? – user244378 Nov 12 '17 at 15:02

  • Yes you can from boot camp just boot to Windows and you know where you can see your c drive and disks you can access your Macintosh HD partition and then you can copy your stuff if this doesn't work then comment. – user244378 Nov 12 '17 at 15:49
  • @Geek yes i already copied my important stuff. So, the only solution for bootloop is reinstall macos for now? – oguzhanvarsak Nov 12 '17 at 15:50
