    Hi Robbie!

    It has been awhile!

    Yes, there are external optical drives that will work with your eMac.

    Actually, OWC ( has both FireWire and USB 2.0 optical drives that should work with your eMac.

    Here's the link.

    A regular DVD player doesn't work like that.

    You need a dedicated read/write optical drive that can actually transfer various types of data over USB or FW to a computer that can interpret that data from disc.

    A quick note about RAM. You can install 2.0 GBs of RAM into your eMac.

    I would advise that you install the max. 2 GBs of RAM as OS X 10.5 Leopard run like snail on only 1 GB of RAM.

    My Mom's eMAc can only run on 1 GB of RAM plus the OS is running off an external FW hard drive (because the eMac's internal 60 GB hard drive went kaput) and it runs, but because of this double whammy, it runs fairly slowly compared to how it used to run on OS X 10.4 Tiger.

    We had to update her eMac's OS X because she has an iPad that needed to be sync'd to a newer version of iTunes that was only available on OS X 10.5 Leopard.

    So, you really need to install the full 2GBs of RAM.

    My own G4 1.25 Ghz tower PowerMac ran OS X 10.5 Leopard great on 2 GBs of RAM.

    It is a very good idea and prudent to have a good backup of all your important data.

    Either backup to CDs/DVDs, USB Flash drive/s or external hard drives that you must purchase.

    If your plan is to erase/reformat your internal hard drive and completely reinstall OS X 10.5 Leopard, then having a backup of your data is needed and crucial.


    On another note about an external optical drive, does your eMac's internal optical drive work and does it, at least read DVDs. You can test this by installing an older DVD movie disc into your drive. An older DVD movie disc won't have the encryption protection that most fairly new DVDs have now. I don't think more recent DVDs will play on your eMAc if it has DVD read capability.

    Then, you wouldn't need to purchase an external optical drive if the one in your eMac works and, at least reads DVD discs. You could even see if your Leopard install disc will work in your eMac's optical drive.

    eMac models either shipped with just a CD read/write drive, CD read/write, DVD read drive OR a CD/DVD read/write drive.

    It would be good to know which one your eMac has.

    You do not have to uninstall 10.4.

    You can install OS X 10.5 right over 10.4 by completely erasing your hard drive and reformatting the drive.

    Here's a link to properly installing OS X.

    There is NO TOOL you need to download or install other than having an OS X 10.5 Leopard disc!

    You did not need to click that link on that page. I linked that page to give you the procedures for installing OS X 10.5. Not to download anything.


    Try starting from the optical drive by restating your Mac and hold down the C key until the disc in the optical boots.

    Is this optical drive connect by USB drive or FireWire?

    I am not sure, but  I do not think older PowerPC eMacs can boot from a USB drive. I think it needs to be a FireWire connected drive.

    Both optical drives and hard drives on older PowerPC Macs, if memory serves, can only boot over FireWire.

    If this optical drive is connected via USB, it may not boot.

    Try holding down the C key at startup or restart and wait and see if the disc in the optical drive boots up.
