Back Story: my employer gave me her old MBP (late 2011, 500GB) because she cracked the trackpad. I fixed the trackpad, and wiped the MBP clean, reinstalled High Sierra--and must have turned on FileVault while doing so (honestly don't remember). So, 3 days later and FV is still trying to encrypt. I can't stop it. I have no data on the MBP. At one point I clicked on "Update" in the App Store, and then I kept getting error messages that High Sierra couldn't install: macOS cannot be installed because your computer is currently encrypting data the path /system/installation/packages/osinstall.mpkg appears to be missing I tried First Aid in Disk Utility. I made a Bootable Install on a USB Flash, and installed from that in Recovery Mode, and it finally installed High Sierra, but it somehow continued with the previous FileVault encryption. From other suggestions, I typed in Terminal "diskutil cs info /Volumes/<name>" and it came back: -bash: syntax error near unexpected token 'newline'Then I tried typing "diskutil apfs list" and it came back: No APFS Containers found I *think* that means I am not using APFS, correct? At this point, if someone can tell me how I can do a clean OS install WITHOUT activating FileVault I would be forever grateful!!!
