Booting issue

I installed High Sierra on my 2011 MacBook Pro to run Studio One DAW. Was importing wav files from a digital recorder when Studio One started to glitch. Now when I turn on my MacBook, it will not load, all I get is a white screen with a circle that has a line in it

MacBook Pro 13″, macOS 10.13

If your Mac starts up to a circle with a line through it



A circle with a line through it means that your startup disk contains a Mac operating system, but it's not a macOS that your Mac can use. 



A prohibitory symbol, which looks like a circle with a line or slash through it, means that your startup disk contains a Mac operating system, but it's not a version or build of macOS that your Mac can use. 

  1. Press and hold the power button on your Mac for up to 10 seconds, until your Mac turns off.
  2. Turn on your Mac and immediately press and hold both Command (⌘) and R to start up from macOS Recovery. 
  3. While in macOS Recovery, use Disk Utility to repair your startup disk.
  4. If Disk Utility found no errors or repaired all errors, reinstall macOS.
  5. If you still need help, please contact Apple Support.
