Has Apple messed up the use of external SD card readers?

Hi,
Has Apple messed up the use of external SD card readers, now the new iMac's with built-in card readers are out?
I could use it fine but now with OSX 6.1 I can't use it, the red light just flashes on it.
I have tried it on the Dell PC with no problems.
Is it really a coincidence that it worked ok before they released the Mac's with built-in SD card readers?
Is anyone else having this problem?

External SD card readers assumably connected by USB should work fine. Your particular machine doesn't have the SD card reader as I see from your mac specs. Simply upgrading to Snow Leopard should not have caused this device not to work.

Check to see if your SD card, in the card reader, is showing up in Disk Utility.

It is possible though improbable that since upgrading to Snow Leopard you are having hardware (your external card reader) incompatibility with your software(osx 10.6.1)...but I doubt this is the case as an SD card reader behaves just as if you inserted a USB Flash Drive into the USB port.

My external reader works fine on 10.6 on 3 different Macs... well, 2 now to be honest.. but one of them will no longer power on. The third, is a brand spankin new macbook..

I am sorry are you thinking that apple has found a way to disable all external sd readers so as to force everyone who wishes to use sd to purchase a new machine ?

10.6.1 has made no difference at all to my SD card reader(s) - they both work fine - if you have a red light flashing on the reader itself, it may be a fault in the reader that is causing the problem.

I don't think he was insinuating that apple purposely disabled external card readers. I think he was simply stating that the external card reader was not working on his machine that has snow leopard and it had been before.

This is a strange topic, but, the same thing happened to me. I was able to use my card reader then for no reason wasn't.

Lucky for my I upgraded to the new iMac with built in card reader but it did make me wonder.

FWIW, My card reader works with my iMac and SL just fine.

Same here...no problems with any card readers on imac

Have you tried the card reader on another computer?

Yes I tried it on my Dell PC running Windows 7 and it works fine.
