PalmOne has released Palm Desktop 4.2.1 software for Mac.

This is the application required in order to view, sort, edit, backup and add applications to a Palm-powered handheld device.

It lets Mac users synch data between the Palm device and the following Palm Desktop 4.2.1 for Mac applications: Note Pad; Date Book; Palm Photos; Voice Memo; Address Book; Memo Pad and To Do lists.

The company says this release includes a new Send to Handheld droplet (version 1.3), which lets Mac users "send image and audio files to the handheld or expansion card".

The release also offers improved Mac OS X 10.3 Panther compatibility.
