SD card reader not working on high sierra

I tried that, but when i Boot with Command+R, it still does not recognize my SDHC in Disk Utility. In system information, it tells me that I do not have an internal SD reader, although I do. Is that software issue? This is a real pain, because I still use SD's quite a bit even though a lot of ppl dont.....

Michail_d, I had this issue as well, but absolutely nothing I tried fixed it. Recently my SSD and motherboard both went bad at the same time. One Apple advisor told me that he has seen Macs do this lots of times, slowly go bad one component at a time. I had my MacBook fixed and it works like a dream.... but if a restart fixed yours, thats great!!

I just installed High Sierra and could kick myself. I can now talk to Siri, but I can't access my SD card. Yet, when I remove it, I get that message about improper removal. It shows up in the disk utility, but I still can't find a way to access the card's contents.

I have Mac mini (Mid 2010) too.

I wanted to downgrade to 10.12.6 but realized sd reader is not working now.

apparently, apple has something against sdcards, probably they're trying to force users to use icloud.

I have been benchmarking all my apple devices with all versions of OSes.

when I upgraded from Yosemite to Sierra, computer speed actually increased (all my other apple computers too).

I was amazed, this was against what everyone was saying about Apple doing forced obsolescence etc.

I though that it was probably a mistake that apple forgot to slow the os down to force people to buy newer stuff.

then I upgraded to high sierra, now computer is even slower than Yosemite. so, well done apple.

I really hope the bootrom update won't cause a problem to downgrade to sierra.

ok, I downgraded my Mac mini (Mid 2010) to 10.12.6.

Now the sdcard is working.

Also the benchmark shows proper speed, not like how it was in 10.13.1

however, there is another problem now. the write speed is slow now.

initially internal ssd write speed was ~104MB/s

after upgrading to high sierra, write speed became ~14.7MB/s

after 10.12.6 clean install write speed became ~33.4MB/s

maybe it's because of the updated EFI/bootrom.

I will try to downgrade and post the result here.

I can view my SD Photos in Apple Photos this will read the SD card, but will only save them to photos. I like to save my photos to back up to an external drive, so need a fix for this. My photo files are too large and expensive to save to the cloud. I would like to have access to my photos, please mac developers fix this issue.

Same here with a 2012 Mac Mini. Mounting SD Card works and SD Card Shows up as connected. Though no Files Can be Copied or Replaced. I can see the contents from the SD Card from my Nikon D5100 but I am unable to Take Pictures out or Rename them while they are inside my SD Card Slot. SD Card shows up as exFat.

You are correct in that this is an OS issue. The first thing I tried was the unplugging procedure. It did not work. Nothing else has either. I suspect there is actually a firmware issue that was likely addressed in an earlier upgrade that some of us may not have installed. I suspect our only hope rests with a bug fix by Apple.

Didn't know about Image Capture. Thanks so much to robogobo as my MacBook Pro doesn't let me transfer my photos from SD card anymore (did upgrade to High Sierra...). I hope Apple fix the issue soon. Image Capture will have to do for now, although not ideal.

At least with your model, you were able to rename the card via Disk Utility, with my 2010 Mac mini (a model many are reporting having card reader issues after installing High Sierra) Disk Utility doesn't even give me that option (unless I plug the card into an external reader, such as a USB reader or my printer's card reader).

Same issue here, on the internal drive, the minute High Sierra finished installing. Transcend SD Card, 2015 Macbook Pro.

Astonishing Apple don't comment here. So many disappointed users, and all we get from Apple?: 🤐

I'm running High Sierra on a 2010 Mac mini. I've tried just about everything suggested in this string. The most recent attempts involved resetting the NVRAM. When I did that I could at least see the internal card reader when I checked System Report. It still will not show up on my desktop with or without a card inserted. One suggestion back a few entries in this thread was to rename the SD Card (I assume the poster meant SD Card Reader) reader in Utilities. Thought I'd try that only to find that the reader does not show up in utilities. So I still can't get the internal card reader to work. Not the end of the world because an external drive connected to a USB port can be read but I have to admit it still bugs me. It should not be this hard to get a fix.

Okay, so I've had this issue too. And I've posted here before. I had a card reader that was not working so I tried a different (new) card reader and it worked. Then it suddenly stopped working as well, interestingly after I downloaded the Sierra upgrade this week. And I found another card reader that uses a USB that was reliable in the past, to no avail. Also, it was not recognizing my camera, and suddenly, after upgrading, it does. But I also used a different cord, so perhaps that was the problem. However, a different cord and different camera did not make a difference for me before. So for me it has been intermittent but very frustrating, not knowing what to expect. I will try the fix someone just mentioned and let you know how it works. Thanks.

Same issue for me ... on a Mac Mini (2010) (last model with a built-in drive), System Report says "This computer doesn't contain any Apple Internal Memory Card Readers", so I suspect this is a possible future fix? (Please, Apple?!) :-)

[Mac Mini > Hardware > Card Reader]

I'm hoping I can use a USB adapter as a workaround in the meantime... but I *love* that this OS release (10.13.3) seems to fix a number of problems I had with older software! Wonder how and why that happened? I was about to install Ubuntu Linux on my Mac Mini, but it's useful again!

Same issue here. 2010 mini. Just had to upgrade to high sierra. And bingo, lost my SD card reader like a champ.

Tried everything in this thread. nothing works. guess i'm going to go get a plug-in sd card reader. Yay!

*** Apple! Nothing but love.
