    I'm having the same problems as others here. I was wondering if other are using "Clean my Mac" software?
    It certainly seems to be as a result of the last software update......
    Come on Apple, whats going on?
    I'm a photographer and dont dont expect these problems.

    This is DEFINITELY not a hardware issue. The card reader works fine on my pc but when I Plug it into my mbp the reader flashes once and then stays dead. The readers getting power and it reads fine on windows so I'm sure it's a software issue. Strange that the bug apparently only affects a few readers though

    I just received the following helpful URL link from SanDisk tech support.

    http://kb.sandisk.com/app/answers/detail/a_id/60

    SanDisk responded within 5 hours of my inquiry. After removing all USB devices from my iMac and reinserting the card reader alone, the reader started working again. I ejected it numerous times from USB ports on the iMac as well as from a USB hub. After plugging my other USB devices back in, I have not detected if there was a device which was causing the conflict. As a precaution I have removed USB devices that are only used periodically such as a Colorvision Spyder2Express device used every 30 days or so to color correct my monitor.

    Hope this helps others with Mac card reader issues.

    The problem is with build in card reader from iMac and not with a USB connected card reader.

    I have tried everything... I also looked at the system profiler as suggested on the SanDisk site, but it does not show up in the list.
    The led is working which suggests power to the unit.
    The only changes i have made to my system was the installation of "clean my mac", & wanted to know if others with the sd reader issue are using this product. (I might remove this application).
    I have also tried all solutions listed here, to no avail, leading me to assume it was in the latest Apple update.

    You guys aren't using DevonThink by chance are you? I had the exact same problem. Just by chance I quite it. Set it to not restart on reboot. Rebooted and voila!

    This is not a problem of DevonThink/___sbsstatic___/migration-images/migration-img-not-avail.png
    After a reboot of my iMac the internal SD card reader works exact one time.
    When I remove the SD card and I plug in again the card reader doesn't work anymore.

    Sounds like you are not properly ejecting the SD card before removing it from the iMac?

    To properly eject an SD card before removal, either right click +(control click)+ on the card's desktop image and then select eject or drag the card's desktop image to the Trash.
  • john3lee Level 1 Level 1 (0 points)
    I thought I had solved the problem by buying a new card reader.
    I plugged an SD card into it, and it stated to mount on the desk top.
    Image capture launched, and i was quite hopeful it was working, until a pop up message appeared & said I had ejected the card improperly..... then nothing.
    Now, the card reader seems to have been damaged, and is now no longer recognised anymore.
    Apple, this is something for you to sort out, or tell us how to fix, and what readers to buy?
    It seems i just waisted £20 on a now ruined reader.
    Incidentally, I have never incorrectly ejected any devise from my computers.

    i am now having this problem with my Macbook Pro the first time i used the SD card slot was flawless but after that i can no longer get cards to mount. rebooting and/or inserting the card while it is powered down does not help as others have sugested. are there any known fixes for this issue?

  • eli.lindner Level 1 Level 1 (0 points)

    Please try blowing out the dust in your card reader before you do anything.

     

    Mine constantly stops working on 3 of my macs and blowing hard into them fixes it.

     

    Must get a dust build up on the contacts or something.

    Okay, I started having the same problem a few days ago. I exported some photos from iPhoto to an SDII card and properly ejected it from the built-in card reader in my 27" iMac. Since then it will only read cards if installed during boot-up. I read through this entire thread but could not remedy the problem. Then I remembered something about firewire & other port problems that can only be fixed by shutting the computer down and unplugging it from the wall outlet. I did this and waited 30 sec before plugging it back in and now it mounts the cards whenever I insert them. I don't recall the explanation but I think it's related to whatever replaced the Cuda chip and I will find out and post the answer here soon.

    Hm, I have this problem still here.

    The SD card only recognise on my iMac when I reboot with plug in SC card.

    When I remove the memory card and plug in again, the card doesn't recognise.

  • riffic59 Level 1 Level 1 (0 points)

    Did you unplug the computer power cord from the wall outlet as I said in my post?

  • joelfromsevenoaks Level 1 Level 1 (0 points)

    This is what worked for me:

     

    Shut down your mac

     

    Press the on button and quickly press and hold Cmd, Alt, R, P, keys wait for the mac to chime 3 times then release the keys, it will chime a 4th time and start and your sd card slot should work again now.
