I’m done with lame file sync programs. I am always jumping around between a number of computers and need the latest files while not online and synced to cloud storage.

Rsync works great, is free, and is already installed on all macs.

Just open a shell and type: rsync –help

or

rsync -avx –progress –human-readable [source] [dest]
