    Greetings...I purchased a 24" Aluminum iMac in November. I was double checking the SuperDrive to see that it can burn a Dual Layer DVD+r (via the "About this Mac" Burner section)...and I see that it cannot burn a DL. My July 2007 MacBook Pro has a superdrive that can burn a DL DVD.

    So I wanted to check with other Aluminum iMac owners...Does your 24: iMac Aluminum have a superdrive that can burn a DL? Could I need some sort of firmware update? or is the DL-capable Superdrive only available on the 24" with the 2.6 ghz processor?

    I was thinking of calling Apple to complain.

    Comments...thoughts appreciated.

    Looks like all Aluminum iMacs can burn Dual Layers. You are probably looking at the wrong thing. Why don't you actually try to burn a dual layer disk?

    Just checked & even my white 24" iMac can;

    Vendor Product Rev

    Interconnect: ATAPI
    SupportLevel: Apple Shipping
    Cache: 2048k

    So your newer model should be ok.

    I'm retarded...

    I just looked again at the "DVD-Write:" value in the Disc Burning section of system profiler...here's what it showed.


    Firmware Revision: FM0S
    Interconnect: ATAPI
    Burn Support: Yes (Apple Shipping Drive)
    Cache: 2048 KB
    Reads DVD: Yes
    CD-Write: -R, -RW
    DVD-Write: -R, -R DL, -RW, +R, +R DL, +RW
    Write Strategies: CD-TAO, CD-SAO, DVD-DAO
    Media: Insert media and refresh to show available burn speeds

    I swear I did not see the DL on Sunday...Getting too old...too blind...too mentally challenged.

    Sorry for the Chicken Little...

    Thanks for the comments.

    No worries.. sh*t happens.

    I've found that sometimes System Profiler information isn't correct.. that's why I dug up that command.
