How to Mount Multiple EFI Partitions? - macos

Question

I’m trying to create an Applescript-Objc to mount multiple EFI partitions, but I’m not able to mount the EFI partitions on external drives only those on the internal disk,
what I've done so far is this:
set a to do shell script "diskutil list | grep EFI | grep -o -e disk[0-9]s[0-9]"
set b to do shell script "diskutil info " & a & " | awk '/Identifier/' | grep -o -e disk[[:digit:]]*"
set c to do shell script "diskutil info " & b & "| grep 'Media Name' | awk /'Name:/{print$5,$6}'"
choose from list c with prompt "Multiple EFI partitions found:"
display alert "Do you want to mount the EFI partition?" buttons {"Yes", "No"} default button 1
set response to button returned of the result
if response = "Yes" then
do shell script "diskutil mount " & a with administrator privileges
display alert result
end if
Note: when asked the user I want the disk name to be displayed and not something like: ''disk0s1''
Thanks in advance!

I wrote an EFI mount/unmount utility applet a while ago that uses an NSAlert with a combo box to try to avoid the death by dialog typical with AppleScripts. I extracted the script from that and added disk names to the initial dialog - the alert stuff makes it a bit longer than your snippet, but there should be something in there you can use:
use AppleScript version "2.4" -- Yosemite (10.10) or later
use framework "Foundation"
use scripting additions
property alertHeader : " --- CAUTION ---" & return & "This utility works with EFI boot partitions -" & return & "Administrator authorization will be required."
property resources : "/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/"
property leadText : " "
property identifiers : missing value -- this will be a list of the EFI partition identifiers, e.g. {disk0s1}
on run -- example can be run as app and from Script Editor
if current application's NSThread's isMainThread() as boolean then
doStuff()
else
my performSelectorOnMainThread:"doStuff" withObject:(missing value) waitUntilDone:true
end if
end run
on doStuff() -- the main stuff
set theDisks to setup() -- set up properties and get disks with EFI partitions, e.g. {/dev/disk0}
set reply to {button:missing value, answer:""} -- preset a previous empty dialog result
repeat -- forever
set theAnswer to answer of reply -- use previous
set reply to (showAlert given settings:{title:"EFI [un]Mounter", message:alertHeader, information:"EFI partitions have been found on the following disks:" & return & return & theDisks & return & "The EFI partition of the specified disk will be [un]mounted." & return & "Enter the disk identifier or select one from the menu:", answer:theAnswer, icon:(resources & "AlertCautionIcon.icns"), buttons:{"Cancel", "Mount", "Unmount", "More Info"}})
if button of reply is "Cancel" then error number -128
set diskID to checkID(answer of reply)
if diskID is not missing value then -- found it
if button of reply is "More Info" then
set reply to moreInfo(answer of reply) -- result of the moreInfo dialog
