Does anyone know whether MissingSync works with the latest OS (BlackBerry Device Software 4.2.1.96 as far as T-Mobile is concerned)?

PocketMac does NOT work with the latest OS, as they even admit on the help website:

"Problem

The PocketMac software does not recognize the BlackBerry device. When attempting to synchronize the BlackBerry device with a Macintosh computer using PocketMac for BlackBerry devices software, the BlackBerry device user receives the following error:

PocketMac SyncManager - There were warnings generated during the sync. Would you like to view them now?

Clicking Yes generates the following:
