    Hi Guyz,


    Its seems that all of you are using the new 2011 MacBook Pro's.

    As per my knowledge the new MBP's boot up n 64 Bit Mode.


    Has any one tried the same using the 32Bit Mode.


    One can boot up in the 32 Mode by pressing the "3" and "2" key at startup.


    Can you please try this out and let us know if the problem persists.



    Ashwin Bhadra.

    I'm actually a little relieved to hear that I'm not alone.


    I have a six-year-old camera that won't use high capacity cards, but I have a 2 GB Sandisk card which my card slot is having trouble reading. It took three or four insertions (and a little bit of cussing) for it to finally mount.


    The fact that this is a common problem likely means that a fix is coming. I was afraid it was a problem with the card slot in my new MacBook Pro.

    I have now tried starting in 32 bit mode on my 1.5 month old Macbook Pro. Unfortunately it did not help :-(


    PS: I verified in activity monitor that it was in 32 bit kernel mode.

    Maybe the problem has been fixed.

    I don't know anyone who is in the OS X developer program... so I don't know anyone who could test it... but hopefully OS X Lion will resolve the issue for us.

    Developers are under a non-disclosure agreement. They can't tell you anything about Lion that Apple hasn't formally announced.


    Has anyone here tried their SD cards after running the fairly recent firmware update (available via Software Update)?

    I did the 10.6.7 update on March the 22 2011. And I did the firmware update on June the 1st 2011 on my new MacBook Pro 2011 i7. I think you are right, it might be the firmware update the culprit.

    Waiting for the next one and using an external card reader in the meanwhile.

    The trouble I had with my Sandisk SD card were prior to me applying the firmware update, so that wouldn't appear to be the problem.

    Hi Guys,

    I recent upgraded my MBP from the 2006 15inch model to the latest 2011 15inch higher end series unibody, and I'm experiencing weird problems with the SD Card reader.

    I use a Sandisk SDHC Extreme Class 10 SD Card and have problems getting it to read through the inbuild SD card reader.

    I tried the following:

    Reformatting on Disk Utility
    Reformatting on my Canon 450D
    Restarting Laptop
    Resetting PRAM
    Resetting SMC
    Repairing Disk Permissions
    Repairing Disk

    All of these did not solve my problem. I have a card reader which when plugged into the MBP, works fine and detects the card.

    The Weird Part

    I plugged the card into a friend's iMac and it detects it every time. And then right after I do that, I plug it into my MBP, and it detects the card, but the problem is once I eject it, and slot it back in, it fails to detect again! However if I try this method again (Slot to iMac, remove, slot back to MBP), it will fail the second time.

    Now when I take the card and put it into the camera, and take a photo, then slot it back into the SD slot, it detects the card once more, repeat the steps again, and without fail, the card is undetectable again, unless I do something like erase an image off the sd card using the camera, the MBP will then detect the card again upon putting it back in.


    Does anyone here have this same odd experience or do I own a possessed MBP/SD Card?



    I just upgraded to OS X 10.6.8 and the problem appears to be fixed... I was able to read 2 different SanDisk 16GB 30mb/s cards twice... 

  • reimon.andisuwa Level 1 Level 1

    Thanks for letting know the updates are available already. i do hope it fix the problem forever.

    i'm downloading updates now.. *finger cross*

  • Bernard Scherler Level 1 Level 1

    I have updated to OS X 10.6.8 and tried a Sandisk and a TDK SD Card and no one works....

  • reimon.andisuwa Level 1 Level 1

    thats weird Bernard, i've update to 10.6.8 and my SD Extreme 8GB class 10 works now. I hope you can find solutions for your system

  • DWFaust Level 1 Level 1

    I still don't get it... I am still convinced that it's a software issue... and, as I said (above), the OS upgrade does fix the issue for me - and it appears to be true for others... yet some, like Bernard, are still experiencing the problem. C'mon, Apple, come clean about this one... please? (and yeah, I realize that they don't actively monitor these forums - they should.)

  • Matt W Level 1 Level 1

    I can confirm my 32GB SD cards now work every time

  • ligaard Level 1 Level 1

    Upgrading to 10.6.8 didn't work for me at all, but upgrading to 10.7.0 (Lion) worked :-)
