I have an Intel MacBook running OSX 10.5 and a BlackBerry Curve. PocketMac simply does not work reliably. It will sometimes do a reasonable job of synching the calendars, but it hopeless with contacts (which is what one really needs to synch!) The app hangs or crashes four out of every five times. Constant data purges, resetting to first synch state, and cleaning of sync files do not solve the problems.

The support functions at both the RIM site and PocketMac are too basic to be very helpful with this.

Until someone else develops a product that works, my advice is that if you have a Mac, don't buy a BlackBerry. They do not work well together.
