MacBook EFI Firmware Update

[Axemantitan]

I found this item in my Utilities folder. When would I ever need to use it, and what changes would it cause?

Ugh, I thought that was from my old MacBook and was transferred over with Migration Assistant.

I hope it wasn't needed because I deleted it!

When you do an OS X update that is when you will get the EFI updates. The EFI icon in the utility folder doesn't do anything that I could see, when I tried to use it.
