    What Mac OS X can I run on my iMac (2007)

    Recently, my son gave me his older iMac 6.1 (purchased in 2007) It has Intel Core 2 Duo processor, 2.16 Ghz, 4 Gb Memory, bus speed 667 Mhz and 1 Tb Hard Drive. The serial # is W864437AVGN. Boot ROM version is IM61.0093.807

    I reloaded, from supplied OS X disks, the Tiger (10.4.11) operating system.

    My first question: Can I load any of the other OS X Versions, namely, Mountain Lion and Mavericks??

    Thanks for your help

    After Snow Leopard 10.6 came Lion 10.7 then Mountain Lion 10.8 and latest is Mavericks 10.9. There is a Yosemite coming. Mavericks may be questionable on a 2007 Mac, hardware issues, didn't work for a lady on her MacBook.

    I read that my iMac need to be at iMac ID level 7.1 or higher, in addition to snow Leopard (1.6.8) or higher. Is there a BIOS or Firmware upgrade to change to iMac ID 7.1 or higher?

    A Mac report said that I have the latest level Firmware (IM61.0093.807). Am I at a dead end??

    Thanks for your help!

    System Requirements:
    Mavericks http://support.apple.com/kb/HT5842
    Mountain Lion http://support.apple.com/kb/ht5444
    Lion http://support.apple.com/kb/ht4949 http://support.apple.com/kb/SP629
    Snow Leopard http://support.apple.com/kb/SP575

    my son gave me his older iMac 6.1 (purchased in 2007)
    It's more about when it was built, no way to know how long it was on a shelf before he got it.

    Mountain Lion may the the latest you can use.

    On a 6,1 iMac (a.k.a. "late 2006"), Lion is the highest officially-supported OS.
    You can get Mountain Lion to run, with a bit of hacking: http://forums.macrumors.com/archive/...t-1325709.html
    Mavericks requires a lot of hacking: http://forums.macrumors.com/showthread.php?t=1593194

    Another question. I could not find the apple diagnostic tools on the computer or on the snow leopard disks.

    I heard of a diagnostics tool called TechTools Pro Version 7 - Cost $99.99. Any comments?

    Thanks for your help
