If you format a drive in macOS using Disk Utility (using the default GPT partitioning) it will indeed create an EFI partition. I use gdisk to delete the EFI partition on my non-boot drive(s). You can read instructions on how to accomplish this here (3rd answer).Design your system so that there is only one disk (an SSD if you like speed) that has an EFI partition that contains the Clover boot loader. Of course in OS X, all (I think) formatted drives will have an EFI partition, but you do not want two EFI partitions that contain ANY boot loader – that includes Clover, Chameleon, Chimera or whatever.
