Afraid not. You're referring to an internal reader, I assume? The one on my late 2013 15" rMBP's been fine throughout the betas - nothing unusual at all, with a 32GB SanDisk 95MB/s.Since upgrading to Yosemite I have been having issues with the SD card reader. It won't recognize any of my cards. Has anybody else had this issue?
No problems here. I have the StorEdge cards and a couple from Nifty plus the stock SanDisk. I am having no problems reading or writing from/to the cards in Yosemite DP4.
I can mount FAT32 SD cards on Beta 2, just an FYIMaybe not quite the same.
https://en.wikipedia.org/wiki/File_Allocation_Table#FAT32 are the opening poster's cards all FAT32? And so on.
I just upgraded (Dec 2014) and my early-2011 MacBook Pro will no longer read my SD card. I use my camera constantly. This is a huge wrench in the works. Has Apple posted a fix?
I downloaded updated driver installer
I've never seen iMac 2008 with card reader or jMicron controler ?I am on 10.10.2 and cannot get SDHC cards to download to our 2008 iMac. It always freezes partway through copying and shows "disk i/o error" messages in the console along with a bunch of other stuff. Card and reader works perfectly on my 2012 MacBook Pro.
Personally I think the JMicronATA driver is old and doesn't work right. Someone at Apple screwed up. My driver shows as being from 2012, and it loads during when the card is to be used, then fails.
Either way Yosemite is an absolute joke, ususable piece of trash that I wouldn't wish on my worst enemy. Ugly icon redesign, can't download photos off a simple USB card reader, rush slow, tries to do lots of bells and whistles with notifications and social media but JUST DOESN'T FREAKING WORK. Worst MacOS release of all time.
Good news the updated driver works for you .I downloaded updated driver installer
Rebooted now my card reader works perfectly
OSX 10.10.1 MBP MID 2012
This worked for me too. Many thanks. There are a lot of "solutions" out there to this ignored issue with Yosemite but this uniquely makes sense. Perhaps Apple would consider including this driver update in their next patch?
