Does anyone's iMac read the SDHC cards?

Question

My iMac will read SD cards, but the new type SDHC card is not read. If your iMac does, what reader do you use? I have an older reader for multiple different cards.
I used to have a 4G SD card which the older reader and the iMac would input. The card broke so I bought a SDHC 4G card and the iMac does not read it.
I wonder if I buy a SDHC card reader/USB that the iMac will 'see' the SDHC card?

Answer 1

The older PPC-based early LCD iMac 1 GHz PowerPC G4, 1 GB ram Mac OS X (10.4.11)
of the OP is a bit different in vintage hardware and design, without a built-in reader.
{Most other references between a newer twice-removed model iMac based on Intel chips
and other improvements, is something to consider in this thread. And that makes the link
provided not applicable to the computer in question.}
The newer external card reader should be adequate to resolve this issue, since the OS X
version should be capable to handle the data once the reader is upgraded. I'd hold off on
any changes in the system software, since the reader should plug & play. The last thing I
do is add software that came with some peripheral, when my system is otherwise fine.
{If the card in question is used in relation to a camera, for awhile, one can just plug the
camera into the Mac and use that to read the card. I rarely use a card reader with mine;
since the DSLR and other digital cameras transfer fast enough & with little battery loss.}
Good luck & happy computing!
