SD card reader not working on iMac

I appreciate and understand that and I will be doing so but this topic has been running since June 12th 2010

Surely someone must have contacted them by now.

If its not been fixed in all this time it seems unlikely that it will.

I had this problem too (see earlier post) and it was a hardware problem. I brought to an Apple store and it was fixed under warranty. I have not had the problem since.

This is definitely NOT a hardware issue. Its like thousands of us out there with the same problem. I also find the fact that Apple has not responded yet quite unprofessional.

Have you contacted Apple?

Having looked in the slot on my 2011 Macbook Pro with a torch, I noticed quite a lot of dust in there. Used an aerosol air duster, inserted a card and it works perfectly!

I think a lot of you might find the same. The slot is going to pick up dust and debris and it's causing a bad contact with the SD card.

If you've cleaned the dust away and it still doesn't work, try gently wiggling it around too.

Thanks Gavin 4077. I've had this problem the last couple of days and started reading this thread with despair. Then I got to yours and blew out my SD slot. Hey presto - all working again.

Thanks.

I found the solution to my problem today at this link. Apparently it's a hardware technicality. Check it out guys. It worked like a charm for me. http://cvil.ly/2011/10/30/imac-sd-card-reader-fix/ Hope it works for you guys.

It's a hardware problem? Hm.

And why recognized the SD card on reboot?

That's strange.

Well, I said apparently, is a hardware technicality, not a problem. In reality I could not assert one thing or the other, since I'm not a technician myself. It bypasses the switch (if it is really a switch) on reboot? Could it be a software issue? I don't know for sure. Deal is, after having this problem, it worked pretty good for me doing what I read at the link I posted. Not a problem since.

Thanks for the gopro trick!! That must be what it doing it. I thought it was bootcamp or VMware related, looks like its not.

I've been having this same issue and I'm 100% sure my problem isn't hardware related. After reading through these posts I realized that my sd card slot stopped working right around the time i installed gopro's cineform studio. I'm almost 100% sure thats the issue that caused my slot to stop working. The only fix I have for it now is to put the sd card in the slot and then close the lid to the mac so it sleeps and then open it again. Once I do that the sd card mounts. Has anyone else found another way around it or would deleteing cineform studio fix it?

Have you actually tried the suggested hardware fixes? Making sure the button inside the reader slot isn't stuck by using a toothpick or some similar poking device? I don't think you can say you're 100% sure just because of a potentially coinciental software installation.

My iMAC 27" (late 2010) have long term SD Card reader problem.

I will solve this problem myself.

Finally I would like stop discussion in this Forum about Hardware / Software issue forever and stop long term invistigation.

So.

I've purchased internal SD Card plate on Ebay.com + special Apple tool kit on Amazon.com (http://eshop.macsales.com). Totall price is about 30 USD (incl. postal exp.)

Plate already received.

I have tired to clear out the slot with a toothpick and blown air into it. I'm only saying for me I'm 100% sure my issue is software related. I can insert and take out the sd card 50 times and it'll never mount, however if i jsut leave it in and close the lid of my macbook and then open it, it will mount right away. Once it does mount I can eject it and re-mount it as many times as I want as long as it doesnt go to sleep again.

Hello all.
