Hi all,
I've run the Software Update app on my new mac book pro and it installed EFI update 2.2. After I had the update installed, I came up with the apple site saying that it should apply for lion and above. However, I'm running snow leopard. Should I worry about having made this updated, even if it was made through apple software update app?
thanks,
Wendel
MacBook Pro, Mac OS X (10.6.8)
No. If Software Update offered it, it's appropriate for your Mac.
You're on 10.6.8, which is the required version of SL prior to installing Lion, so that's probably why it's been offered. There may not be any benefits from it until (if ever) you install Lion, but it will certainly do no harm.
Hi, I have a MacBook Pro 2011 15". It was shipped only with Lion. But i could install Snow Leopard, if i got the original DVD (10.6.7), from before Lion. Not even Apple knew that. Now, the SoftwareUpdate tells me to install the MacBook Pro EFI-Firmware-Update 2.2, because it is actually a Lion-Mac. Now i'm afraid, that the update makes it unpossible to run osx 10.6.8. Has anyone tried it?
Have you actually read the thread?
You don't have to install an update just because it's offered. In your case, install the 10.6.8 update, then the firmware update.
"Not even Apple knew that"
You mean the odd guy on the Genius bar didn't know it. Apple certainly do.
Have you actually read the thread? I have installed 10.6.8 and the softwareupdate tells me to install the MacBook Pro EFI-Firmware-Update 2.2. But that update runs only on Lion or later. I need the firmware-update, because i need the thunderbold-fixes.
Yes, 10 apple-guys dont know, if that macbook pro running with 10.6.8, since it was shipped with lion. 10 apple-guys told me, it cannot work.
Yea; sorry for being a bit crabby last night.
Understandable that the store guys might not know, but there has been quite a lot of discussion on this topic in the forums over the last month or so.
Basically, most of the stock currently on sale with Lion would have left the factory with SL, and the SL discs for those should still exist - if you can get hold of them. Whether or not the retail SL disc would work is less likely as it's not been updated from 10.6.3, whereas the Macs in question would have been 10.6.6 most likely as a minimum.
As for the FW update, as I replied above; if software update offered it, it won't do any harm. It may not do anything useful unless you go back to Lion, but it won't do any harm.
And you don't have to install it. Your SL installation is unlikely to have any problems if you don't.
