I was trying to re-install Windows through Bootcamp, and it was stuck at partitioning. I quit Bootcamp, and now in the disk utility I get this error, even when in recovery mode:
First Aid found corruption that needs to be repaired. To repair the startup volume, run First Aid from Recovery
I am backing it up right now, but how can I fix this? It's my school computer with important stuff, so any help is appreciated. It's a MacBook Pro (Retina, Late 2013) running macOS Sierra.
