MacATM worked fine in Tiger, though the withdrawal fees were a little high. After upgrading to Leopard, though, it stopped recognizing my PIN. Now the system refuses to eject my card, and MacATM's technical support only has a phone menu that loops every time I press (4)-I do not have a butterknife. All the right hand side buttons are stuck on "Instant Reverse Mortgage", severely limiting my transfer options. MacATM also messed up my print drivers to where half the alphabet is now substituted with tiny pictures of former Soviet currency. My girlfriend was mugged while using the previous beta release, though to be fair to the development team she shouldn't have used MacATM so late at night.
Still, more useful than Bob. 3 out of 5.
