I downloaded and installed the: Mac mini EFI Firmware Update 1.6 on my mac mini running 10.8.1, was I correct in doing this ?

I didn't see this update come up in "Software Update"

If I was not meant to install this update, would it cause ANY damage at all to my mac ( this is my second as I dropped the first 😢 )

If I were to re-install ML would this fix any errors that this may have caused ?

The bottom of the page I link to says:

Boot ROM or SMC Version Information: MM51.0077.10

But when I click on "About this Mac" it says:

Boot ROM Version: MM51.0077.B10

SMC Version (system): 1.75f0

What does the additional "B" mean?

My mac mini is the Mid 2011 Model.

I am sorry if I am sounding super paranoid about this, but I don't want to have caused any permanent damage.

Hello,

It's somewhere between almost impossible & impossible to install the wrong EFI Update with all the checks it does! 😉

Mac mini (Mid 2011) with Intel graphics	Macmini5,1	MM51.0077.B10 (EFI 1.6)
Mac mini (Mid 2011) with Radeon graphics	Macmini5,2	MM51.0077.B10 (EFI 1.6)
Mac mini Server (Mid 2011)	Macmini5,3	MM51.0077.B10 (EFI 1.6)

Not sure what the B means.

If I were to re-install ML would this fix any errors that this may have caused ?

No, Firmware is unaffected by any OS change or re-install.

This seems to answer my question, but I have the "AMD Radeon HD 6630M 256 MB"

How did it let me "re-install" the SAME firmware ? 😕

So this wouldn't have done anything that could damage my mac by "re-installing" the firmware ?

Radeon Mini is the second in the list.

No damage done if you reinstalled, but I'm not sure I ever tried reinstalling a Firmware Update!?

Were you at 1.6 before???

I am not 100% sure if I was on 1.6 before. I would have thought that I would not have been able to install the 1.6 update if it was already on my system 😕
