Hello, I am trying to identify a older imac I have to see if its possible to upgrade the OS to Lion (for additinal software install puposes). I have tried matching serial numbers to the identify your iMac webpage : https://support.apple.com/en-us/HT201634 but the info Apple gives is extremely vague. I know that its a 2006 because its white, but I would like to know which of the late or mid versions it actually is. This is what Apple said my old computer is: OBS,IMAC (24-INCH) ...what? Why is Apple so vague with this info? I guess what I should really ask is, can I buy and install Lion on this computer? I've read that it is possible on some older iMacs, but not recommended by Apple for whatever reason. Any help would be appreciated. Thanks.
