    Is my Imac capable of running Leopard?
    Hi,
    I Have an Imac that is a couple of years old. Here is the system profiler specs:
    Model Name: iMac
    Model Identifier: iMac4,1
    Processor Name: Intel Core Duo
    Processor Speed: 2 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache (per processor): 2 MB
    Memory: 2 GB
    Bus Speed: 667 MHz
    Boot ROM Version: IM41.0055.B08
    SMC Version: 1.1f5

    My daughter just bought Ilife 09, and while I was reading the requirements, it says it requires OSX 10.5 (Leopard). I am running 10.4.11. I would buy Leopard, but I heard it needs a computer with a minimum bus speed of 867 MHz. It seems to be a domino effect. I would buy it, but I cannot return it opened. Any advice would be greatly appreciated.

    Thanks

    My 1 year old macbook has the same bus speed as your imac (667 MHz) and has been running leopard smoothly since I upgraded from tiger 6 months ago.

    According to apple your processor needs to be 867 MHz or faster, so your imac should run leopard fine.

    There are Macs out there with G4 processors running Leopard smoothly. You should be more than fine with your Core Duo processor.

    It's not the BUS speed, it's the CPU Clock speed that has to be 867Mhz and that is with a G4. Any G5 and any Intel based Mac will run Leopard just fine. Main thing is to run smoother give it all the RAM (Memory) you can.

    The 867MHz Leopard requires refers to the minimum processor speed whereas the 667 MHz quoted is the system bus speed ~ two entirely different things.

    Of course your Intel machine will run leopard very nicely and even better with more memory.
