I'm curious if a 10.6.6 system recovery disk set, originally shipped with a May 2011 21" iMac, will work with a May 2011 27" iMac?


The reason for this question: I recently purchased a May 2011 27" 3.4 Ghz core i7 iMac with the 2Gb Radeon 6970M video card. This imac currently has Lion installed on it. I cannot use Lion because Final Cut Studio 2 does not work with Lion (or so I've heard on many online forums), and I use FCS 2 for work. So, I had planned on downgrading my iMac to Snow Leopard.


I've researched the Lion to Snow Leopard downgrade issue in-depth over the past few days and am getting mixed answers. One says it cant be done, another says it can be done with a retail version of SL, still another says it can be done but the best way to do it would be to find 10.6.6 install/recovery disks and use those (this was the "preferred" way to do it because, they say, the iMac will perform best and fastest if the 10.6.6 disks are used.)


Wanting the best possible speed out of my iMac, I chose to search for 10.6.6 disks. Luckily I found a brand new unopened unused set, but they are for a 21" May 2011 iMac. I understand how one disk may not work with another Mac, in the Apple world, which is why I ask.



Incidently, I did chat online with Apple support earlier, and asked them the same question. I was told that it wouldnt work because the 21" 10.6.6 disks were factory installed to that 21" iMac, and were "one use", meaning they could only ever be installed and used on that one particular iMac and no other, not even another 21" iMac (which seems very strange to me). This discussion is what ultimately lead me here, asking all of you fine folks.



Thanks in advance!
