SD card reader not working on iMac

Guys!

I've open the SD Reader and found that problem in micro contact group> NO CONTACT.

This device VERY DIFFCULT to repair. Better to buy new one.

This is a HARDWARE PROBLEM.

Do a PRAM reset: Shut down the computer. power it on and hold down Command, Option, P, and R. Wait till you hear the start up sound twice, Release the keys.

The same issue! I also installed gopro's cineform studio and lost SD card slot mount.

100% GoPro cineform fault. Deleted and SD slot started working, picking up cards!

Can you explain how you deleted Gopro cineform? Just delete it from the applications folder or did you use a application remover?

first I opened CleanApp application and chose "prepare to delete" option. Application found 3 files. Then I uninstalled GoPro cineform with uninstaller uncluded, and "finished it" with CleanApp deleting the 3 files previously found. Inserted SD card and it was mounted.

I had this on my macbook pro and they changed the motherboard...

to raimeb Your SD slot didn't mount after Gopro cineform installed?

After more than 2 years, suddenly my build in SD card reader didn't work. Poking with a (soft) toothpick (see also picture in the article) worked inmediatly for me. Did the trick without switching off, or reboot.

I had the same problem with my 21" iMac...SD card was only recognized after reboot or wake from sleep. I tried the toothpick trick I found in this thread and it seems to have fixed the problem, at least for now. I've been swapping cards in and out and they are recognized each time.

Here's another description of the problem and solution I found:

My 2yro MBP's SD card reader stopped working on holiday 3 weeks ago. Tried everything, then, as a last resort blasted with a jet of air and since it works! Dust - the downfall of Apple products.

My iphone 4s had no sound for weeks and was about to chuck it away when I was told that dust in the charger port made the iphone believe it was being 'docked' to speakers and would mute itself. Cleaned out the port and surprise - the sound started working again! Apple really should design these things to have dust covers like other brands do...

Good shout Andi172, your trick worked on my MacBook Pro.

Thanks very much,

Treacle

Thanks Andi172,

After trying a whole swag of things such as SMC reset, PRAM reset, safe mode, etc, sticking the tooth pick into the SD card reader and pushing that small switch worked for me.

Cheers

DO YOU HAVE APPLE CARE, IF YOU DO SEND YOUR IMAC BACK TO APPLE

It seems that all your replies are typed in all caps - that is considered shouting and not really appreciated because it makes it difficult to read. Thanks.

Hi - had a problem with my SD card - was working fine and I was using Iphoto tried to import the photo's from the card and all of a sudden they where gone. After that I couldn't get the Imac to recognise any SD cards. Suspected a problem with Iphoto, reset SMC and pram no better. Installed latest version of Iphoto - bingo it worked for about 1 minute. Then nothing. I had been clearing a prompt form dropbox asking if I want to import photo's into that - closed dropbox and bingo again - has worked ever since - for some reason dropbox gets hold of the card first??? Anyway ok now - hope this helps someone.
