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

Run this command:

diskutil list
The output should look something like this:

/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

In this case, the volume identifier of the EFI partition is disk0s1

1. Create a mount point.

A mount point is a directory where a non-booted volume is mounted. On Mac OS X, mount points are typically created in /Volumes. We can create a directory called efi within /Volumes by running the following command:

mkdir /Volumes/efi

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

Run the command:

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

That’s it. Your EFI volume will be mounted. Modify it at your own risk.
