EFI Drive Question

[stuprice]

Apologies in advance for this newbie question, but I just bought a 2019 MBP... is it normal to see the "EFI Drive" in the Finder/Locations window?

It contains the APPLE/UPDATERS/MULTIUPDATER folders.

From my reading on the subject, I thought that the Extensible Firmware Interface was supposed to run in the background, and I shouldn't be able to see/access this disk?

Thanks very much!

What are the odds that someone is sharing folder called EFI on your network? I've never seen this, and my DuckDuckGo-fu finds nothing either...

If it was new from Apple, then you shouldn't be seeing the EFI partition and folder. Your screenshot doesn't show the disk or the full window.

If you restart the MBP, does it show again? If it was then it means it is automatically mounting at startup.

What is the full path of the EFI folder (drag it to a Terminal.app window).
Check the mount command to see what disk/slice the path is associated with.
Use diskutil list to see a list of disks/slices.

Thanks for your response.. after re-starting, the EFI disk shows again. This is a new from Apple MBP...

The path is (user)$ /Volumes/EFI

Entering the mount just gives me:

-bash: /Volumes/EFI: is a directory

diskutil list returns with "command not found"

After a few hours of googling I still can't find an answer... it doesn't seem to affect the MBP performance, but from time to time I get a "EFI disk full" warning.. very annoying!

Any other suggestions??

Thanks!

In the Terminal window:

cd ~
diskutil unmount /Volumes/EFI

Restart the computer and see if the EFI is auto mounted again.

Use mount with no parameters.
I think you typed diskutil list wrong.
Show a screenshot if you still get errors.

The EFI partition should by 200MB. The diskutil list command will show the size.
The df command will show the amount of space that is free.
