You won't find any mac drivers for your phone on the Samsung website, nor will you be able to obtain them through Sprint, but I am told it's possible to sync your phone and computer with Mac OSx through bluetooth. I don't have any personal experience with this procedure, but I'm sure you can find info with a quick Google search. Try "a900" and "mac" together for keywords and see if that lands you any results. Let us know how it turns out!
