Mounting EFI partition on OSX

Original Post

1. Discover the volume identifier for your EFI boot partition.

diskutil list
/dev/disk0
 #: TYPE                     NAME          SIZE       IDENTIFIER
 0: GUID_partition_scheme                  *251.0 GB  disk0
 1: EFI                                    209.7 MB   disk0s1
 2: Apple_HFS                Macintosh HD  250.1 GB   disk0s2
 3: Apple_Boot               Recovery HD   650.0 MB   disk0s3

2. Create a mount point.

mkdir /Volumes/efi

3. Mount the EFI partition at the efi mount point.

sudo mount -t msdos /dev/disk0s1 /Volumes/efi

That’s it.
