High Sierra requires a firmware update for Mac ...

I have downloaded High Sierra on my Mac Pro Server Mid 2012 version and the installer says I must run a firmware update before it will install.

Where do I get the firmware update for the computer?

When I perform the steps to do the firmware update the cd-rom drive opens, so I suspect that I need a cd-rom with the firmware update on it.

Hi there, pdarrell, maybe i can help you.

You get the firmware update from Apple via the Internet, to the best of my understanding, you don't need a cd-rom with the firmware update on it-one doesn't exist (ah, if it were only that easy). There's a certain procedure that the High Sierra asks you to do, to do a firmware update before installing High Sierra. However, it's been my experience so far

that it doesn't "take", or at least I haven't seen any evidence that it's doing anything, eg, grey screen with Apple icon on it and progress bar, and it's my understanding, limited though it is, that you must do this firmware update, eg there is no getting around it, and with High Sierra it'll be checking the firmware on a weekly basis. I haven't found a way to get it to work at all, and until there's some kind of fix  or word from Apple,  I'm going to try installing it one more time then leave it for the time being.  i believe your Mac will work fine with the OS it has on it for now, but I may be wrong
