Are your apps ready for Snow Leopard? SnowChecker can tell you
To quickly see which apps are going to have issues under 10.6 and might need to be updated - either by you or by the app's developer - sort the list by status. Red Xs are apps whose functionality is completely borked in Snow Leopard, while yellow alerts represent apps where one or more inessential functions don't work. SnowChecker will sometimes even offer a workaround for these, like running the app in 32-bit mode or disabling Google Gears. Snow Leopard has been out for a while, but if you're just installing now, you should run SnowChecker first to figure out what your compatibility options are.
