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

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)?

You can delete everything from the EFI partition if you wish. OS X will recreate what it needs when the operating system starts. Basically, OS X copies the
Firmware.scap
file from the boot partition to the EFI partition.The files and folders marked below for deletion are not part of OS X.
The rest of the files were put there by OS X or related software.
