Looks like, it's listed as "SDHC" for all of the new iMacs...
Does anybody have SDXC card to test it out on one of the new iMacs?
Lol, shouldn't this have been thought of before?
Got a tip for us?

New 2010 iMac users: do you really have a SDXC card reader? Could you please check?

Hm, if our SD readers are the same as the below MBPs, this would lead one to believe that it is not SDXC.

That's really odd.... Does anybody have new mac mini? I wonder what prod id is used for card readers on new mac minis.
Why do you care how it is listed? That's probably just some programmatic guesswork based on the USB device ID. Maybe it is an ID shared with a "old" SDHC reader which has now been upgraded to also read SDXC.
How about testing it? Either it does read SDXC cards and your fine, or it does not and you'll get a new iMac. Which is more likely?

Before panicking, one might want to read this:
SDHC and SDXC compatibility issues
SDHC and SDXC use exactly the same electrical interface -- the only differences are software (new filesystem to get around the limits of FAT32) and labeling (if it's bigger than 32GB, it's SDXC, if it's 32GB or smaller, it's SDHC). The SD 4.0 specification will allow higher bus speeds for SDXC, but it's not even out yet, so nobody can be compliant with it.
Even the card reader is the same SDHC part as found in older Macs, all it takes for it to use SDXC is software support. (Which makes me wonder if those older units are going to get a sudden miraculous upgrade, but I doubt it.)

Hi All,
I just bought an 27inch iMac from a local apple store yesterday.
After unboxing, I checked if everything was cool with the iMac(dead/stcuk pixel, yellow tinting, any imperfections, etc)
When I looked at the System Profile to check various types of devices, I noticed that it lists the type of SD card reader as "SDHC". NOT "SDXC"!!!!
I did some googling to check if anybody has posted regarding this.. I ran into this short article and looks like upon inserting a SD card, --- Visiting the slot in Disk Utility with an SD card inside shows an "Apple SDXC Reader" ---
(ALTHOUGH the article was based on the new mac mini)

So I inserted my 8GB SDHC card and went to the disk utility but it just displays "APPLE SD Card Reader Media"
Can anyone of you who owns a new iMac check if you see it listed as SDXC or SDHC under your system profiler or disk utility? THANKS~!!!
I would like to check this myself as well. May I ask where in System Profiler do you see the SD card info? I have a 27" iMac and a Core i5 15" MBP and I can't find this info. I don't see anything highlighted on your system preferences screenshot to indicate the SD card slot info.
I just got off the phone with Apple Support regarding this issue. My 27", 2.93 i7
8GB (2x4), 2TB+256 SSD also lists it as a SDHC. They told me that the new computers do indeed have the SDXC card reader, but they listed it wrong on the system profiler. The next software update will address this issue and change the card reader description to what it should be. Does this make sense to you? I'll be happy when someone with a SDXC card actually tries it out. Take care!

Well, it makes sense but what doesn't make sense is how the new mac minis have it displayed as SDXC READER???
You can click on the apple logo on the top left corner --> About This Mac --> More info... ---- This launches System Profiler.
Then under Hardward/Card Readers for iMac
for MBP it may be listed (Not sure as I don't own a MBP)
under Hardware/USB/USB HIGH-spped Bus
Didn't that update already take place? I thought that this was supposed to resolve the SD reader issues, based on what it mentions as being specific to mid 2010 iMacs. Is it possible that the reader's functionality was updated by adding compatibility for SDXC, but the description in the system profiler was somehow overlooked?
Same here. I went through system profiler and didn't see anyhting that looked like a card reader.
It's the 4th one down under "Hardware", between "Bluetooth" and "Diagnostics". Just click on "Card Reader" and another window will appear. Take care!
Yes, that's how I interpret that patch description, now that Apple Support has said this.
After managing to find some time to give AppleCare a call today, here is the outcome.
Firstly I explained my situation:
iMac Core i7, bought over the weekend has Card Reader Type listed as SDHC under the System Profiler. Checked out Tech Specs on Website and the Card Reader is listed as SDXC.
AppleCare Operator's Response:
Your iMac's Serial lists your machine as Mid 2010, you seem to have the latest in hardware revisions that Apple puts into their machines. I'm surprised that your machine lists your Card Reader as SDHC instead of SDXC. Did you purchase your machine online or through a store?
Response: Through a store
AppleCare Operator: Since your purchase is less than 14 days old, please find some time to pop into the store and ask them how they intend to resolve the problem. If they refer you back to us (AppleCare) I will provide you with a Case Number so that when you call back we will have reference of what has been discussed today and if further action is required we will put you through to a senior advisor who will then help you resolve your problem.
So after 20mins on the phone, I now have to find time to go to the Apple store and have a chat with them.
I'll let you know how things go.

I think what that paragraph is saying is SDHC and SDXC in SD 3.0 spec use the same electrical interface.. but current SDHCs are based on SD 2.0 spec(READ the SDHC section in that wiki page) so i am guessing SD 2.0 spec SDHCs use different electrical interface... therefore current SDHC based hosts won't be able to read/write SDXC..
In SD association FAQ page, it says:
Is SDXC compatible with existing SD hosts?
Existing SD and SDHC host devices will not be compatible with new SDXC cards, but existing SD and SDHC cards will still continue to be offered by card manufacturers for the foreseeable future. Existing SD and SDHC cards will work in SDXC host devices.
