I have a question about what should be located in the EFI partition of my macbook. A couple of years ago I dual booted ubuntu with reFind, however recently I erased my main partition to clean up my mac. Now I would like to dual boot arch also using reFind, so I mounted my EFI partition and found this:
BOOTLOG BOOTLOG.OLD screenshot__001.bmp screenshot__002.bmp EFI/ APPLE/ CACHES/ CAFEBEEF/ (empty) EXTENSIONS/ Firmware.scap FIRMWARE/ MBP91_00D3_B0D_LOCKED.scap Ubuntu/ tools/ gptsync_x64.efi reFind/
So I deleted the ubuntu and reFind directories since I want to start with a fresh install of reFind. My question is were the files contained in the APPLE and tools directories created from the old reFind install, in which case I can delete them, or are they integral to the standard mac boot process (so I shouldn't mess with them)?
