    Here i am with a 2010 mini and a freshly today in 64GB SDXC card.

    The card works effortly in my MBA2012 and according to that it's Mac OSX Journalized formatted. Now i read on the internet that the Mini would be capable of using these cards.

    The thing is, he sees the card but it's marked as read-only on the mini, but if i pop it in the MBA it just works

    Anyone got any clues?

    SD Card Sharing & Permissions

    When the Icon for the Card appears on your Desktop
    Right Click it and choose "Get Info", what does it say
    at the bottom under "Sharing & Permissions"?

    When your formatted the Card you may not have
    given another user Permission to Interact with the
    card.

    There it says directly under Sharing and Permissions: READ ONLY

    A few users have rights to R/W (me and one more) I use the same account on my MBA so that couldnt be the culprit

    On the everyone permissions it's read only but i can't change that as goes for the others also no on trying to change permissions

    Info Window

    Ok, with the Info Window visible
    scroll all the way down to the bottom
    and in the Sharing & Permissions box
    in the Right Side Column
    click on each of the three
    Privilages up or down arrows
    and choose what level of
    Permission you would like to
    give to your SD card.

    I would choose "Read & Write"
    Privilages to all three that are
    named. For example (me), Staff,
    and Everyone.

    That should work. When the
    SD card was originally formatted
    these Permissions were probably
    not given.

    Trust me i tried that, but i can't change permissions on either of the users there. Not even when i unlock the lock and login with my root account.

    It's like the entire card is read-only (like you put the lock slider down) and no that isn't the problem.

    Also it's formatted on a ML MBA and the mini is also running ML, and reformatting or partitioning the card won't work either on the mini, but then again on the MBA it formats without a hitch

    Windows Reformat SD Card

    OK, I had that happen to me once. If you have
    access to a Windows Machine or a Digital Camera
    re-format the SD card using either of those.
    Then re-attach the SD card to your Mac, shouldn't
    matter which and re-format using Disc Utility then
    double check Permissions giving them to "everyone".
    That should work.

    Allrighty, i have formatted it on a Win7 machine as exfat, but still the mini won't say it's writeable it stays read only. On my Air it works perfect.

    Any other idea, except for buying a new mini :p Planning on doing that anyways when the new model comes but still i want this to work now.

    Another update, i reformatted it on my MBA again to FAT32 (since i'm not putting 4gb+ files on it) and it stays exactly the same so not able to write or reformat it on the mine :(

    Anyone has an idea?

    Try to slide the copy protection slider on the card in the middle position. I had these Read Only SD errors on several macs with several SD/HC Cards. It is annoying to say the least.

    Tried that just now and no luck. I'm seriously thinking that the 2010 mini while he has a SDXC slot won't be able to write to cards larger than 32GB

    Can you get write access to ANY card? Do you have a small SD card you can try writing to. It could be a bad card reader socket in the Mini.

    I like BeamWalker's hint: How about a mechanical problem? The mechanical write protection recognition in the mini may have a problem in properly detecting the slider position. This could be a card reader problem as well as a problem of the SD card not exactly keeping the specified dimensions of card thickness and slider position..

    In this thread there are some additional suggestions (like e.g. taping the slider area) and some helpful pictures (entry by ynneb 04-22-2008 at 04:07:00 AM).

    Seems that some people fixed their problem by simply deactivating the write protection completely by using a soldering iron, though you may want to try the taping trick first :)

    Yeh BUT, i've tried different cards which all work like a charm and some extra i've picked up another 64GB SDXC one and that also does not work like the other.....

    So i'm not thinking of a defective card reader more like a SDXC spec used on the cardreader which does not allow cards higher than 32GB to be used

    Based on everything you have tried, my guess is that the SD card reader hardware in your Mac mini 2010 is damaged. I suggest you get your Mac serviced.

    I can't tell if you used a passive SD card reader USB dongle on the Mac mini (and MacBook Air). If that works, then clearly your Mac is damaged.

    Good luck.

    If any, you should've picked a 32GB SDXC card to verify if it's indeed a size problem (SDXC is said to be limited backwards compatible to SDHC, though i don't know exactly what those limits are).

    I just want to let everyone know and thanks for the help.

    I picked up a 2011 mini and the card functions flawlessly in that. So apparently the 'SDXC' in the older mini's have restrictions :)
