I currently have a MacBook Pro running Mac OS X 10.5.8 that will not read my 64GB class10 MicroSD card off my GoPro3 camera. I read in another forum that this is because OS X 10.5 doesn't support exFAT format which is what both the card and camera are formated in. Is this correct and is there any way I can easily fix this problem so that it will read it? Any help is greatly appreciated. Thanks.

MacBook Pro, Mac OS X (10.5.8)

    exFAT is not supported by Leopard OS 10.5:


    What is exFAT?
    ExFAT is a file system for your flash drive that’s compatible for both PC and Mac. ExFAT is supported by the following operating systems:

    • Mac OS X Snow Leopard (10.6.5 or greater)
    • OS X Lion
    • Windows XP SP2 or later (with an additional update for exFAT support)
    • Windows Vista SP1 or later
    • Windows 7

    Disadvantages: As a relatively newer file system format, exFAT isn’t supported in older versions of Mac OS X (anything prior to 10.6.5) or anything older than Windows XP SP2. If you won’t be dealing with older Macs or PCs, this may not be a problem. Of greater issue is that most consumer electronics (cameras, camcorders, video game systems) don’t support exFAT, either. If you need to transfer files between your Mac and one of these non-PC devices, you’re almost certainly going to have to format your flash drive in FAT32 instead (via TUAW).

    To use it you will have to upgrade to Snow Leopard )S 10.6;

    Cool thank you for confirming! So if I were so download and upgrade to Snow Leopard would I lose any documents or data, or does it work just like if you were normally updating your software?

    Assuming that your existing applications will also work with Snow Leopard you should not have any problems, but some of them may also require updating, so check that first!

    Yeah the only application I've added to the computer in Microsoft Office 2008 which I've read should still be compatable with OS X Snow Leopard. Other than that do you know if it's possibly to download Snow Leopard directly from the site instead of order an actual hard copy? Haven't been able to find a link for that yet. Thanks for the answer by the way, very helpful.
