Clover Configurator- Which EFI?

[PepsiMan]

I have a pretty successful install of 10.11.4 but need to get iMessage working.
So, running Clover Configurator is needed.
Which EFI do I choose of the 3 EFI shown in the configurator (see attached pic)
How do I make the config.plist writable as I get the 'You don't own the file' error when I change anything in the config.

Thanks!

EFI/CLOVER/config.plist

EFI/CLOVER/config.plist

Thanks for that. Off to find how to make it writable.

just duplicate it and then make your changes backup the old one and move the new one in place
