    Hello, I bought a MacBook 12 retina, and decided to do a clean install. I know the recovery partition can be removed safely but there is a EFI partition which I wonder if I can delete as well?

    I checked there is no EFI partition on my 2011 MBA, I don't know if it will affect firmware update in the future (googled Effect on EFI)

    You can delete the EFI partition, but Disk Utility creates a new one when you create a new HFS partition.

    Your Air has an EFI partition too, it's just hidden.

    I would leave it. According to this page:

    If you wipe the entire drive (eg. by setting it to "1 Partition") during installation then the installer will create a new EFI partition anyway.
