having the same issues. I've uninstalled twice and reinstalled. I can't get it the sync program to see the device. No password on the BB. I think i've tried every suggestion. I have a new mbp running leopard and an 8820 running 4.5
*Just found this at RIM BlackBerry Search Results
When trying to synchronize a BlackBerry smartphone and a new MacBook or MacBook Pro with PocketMac for BlackBerry smartphones, the following error is received:
The BlackBerry smartphone does not connect properly to the Mac computer.
This is a previously reported issue that has been escalated internally to our development team. No resolution time frame is currently available.
Looks like they are hard(ly) at work on it.
