It probably doesn't appear on your list of supported cameras because it was officially launched just over a month ago and has been on the shelves for less than that. It almost certainly is supported in Mac OS X, and it appears to come bundled with Mac software as well as claiming Mac support on the specs, so I'd say it should be fine.
My only concern is that the SD memory card that comes with it is only 32mb. On a camera capable of 10 megapixels, that is pretty small - at high quality you'll probably only fit 15 shots on the card. If you are thinking of getting this camera, make sure you budget a little extra for either a 512MB or 1GB SD card.
Also, remember to budget for 4x AA NiMH rechargeable batteries and an appropriate charger. High-performance digital cameras don't run well unless the right type of batteries are used.
Its easy to see that the "true cost" of a digital camera can often be well over the purchase price, but without enough storage, and appropriate power, you just won't get the results you want.
