EFI and volumes - Necessity and increased safety

[mackenmac]

Hello,

What is the point of the automatically created EFI disk partition when you only use OS? Seems there have been security issues related to this (https://www.tomsguide.com/us/mac-efi-flaw-attack,news-25911.html). If you do not need it, how would you delete it?

I have tried deleting it through Terminal, using some of the codes on these webpages; https://apple.stackexchange.com/questions/122192/remove-windows-entry-from-mac-boot-loader

macOS: Getting Rid of the Windows EFI Boot Entry - The Mac Observer

When you delete your Windows partition from your Mac manually, it leaves its EFI Boot entry. Let's get rid of that, shall we?

Then I get error messages like these:
mount_msdos: /dev/disk0s1: Resource busy
mount: /Volumes/EFI failed with 71

What do you suggest as a solution?

An overview of running ´diskutil list´ in Terminal (After recently having done a factory reset, and installed OSCatalina) is attached.

Also, does anyone know why there are 6 volumes automatically shared, and specifically what they are for?

My apologies if my questions are badly phrased. I am trying to learn this. Has this more to do with potential removal/change of physical components of the MacBook?

You are confusing two different things. The EFI is the firmware that controls the hardware on your Mac. It resides in a chip on the motherboard. That article is referring to a security issue with the Mac firmware. The article is from 2017, so I'm guessing the flaw has been patched.

The EFI partition is used when Apple pushes out EFI firmware updates as a sort of cache while the firmware update is applied. Removing that partition will still leave you with the EFI firmware on the chip that was the subject of the article, so removing the EFI partition will do nothing to help with the security issue mentioned.

tl;dr Don't do anything... you are fine.
