Mac OS X El capitan not booting after i installed a USB wifi adapter driver

that makes sense then optiofix2 is working since it rebooted instead of getting stuck at optio verbose message. it probably was missing a config value for kernel pm.

It kinda works? The screen blacks out but after trying multiple times i got the display brightness to work. Is the anything i should do to prevent this and fix booting without the usb.

you have to transfer the working EFI folder to the HDD. make sure to save the old one or rename the folder to like EFIX just incase those are the files that clover is using. once all is fine you can remove the backup.
