erased my hard drive to factory reset my 2012 MacBook Pro and now I cannot re install high sierra. I reset it because I updated high Sierra and it said that it couldn’t be installed due to a missing or damaged os install (picture one). So after I reset it and tried to reinstall it says FileVault conversion in process. Please help. I’ve been looking on forums and YouTube and cannot figure how to fix this. I am trying to avoid going to the Apple store since there is not one close and I don’t know if they’d charge me for something I may be able to do myself.
