There is no Apple support, though, for the SDHC and SDXC formats.
Apple about Apple:
Which SD card formats work in the SD card slot?
Cards that conform to the SD 1.x and 2.x standards should work. The SD card slot can use cards that are Standard SD (4 MB to 4 GB) and SDHC (4 GB to 32 GB). MMC can also be used in this slot. MiniSD, MicroSD, and higher density formats like MiniSDHC and MicroSDHC can also work with the use of "passive" adapters that conform to the width and thickness specifications listed above.
