With the Mac’s drag-and-drop interface, you’d think duplicating files would be a snap. And if all you’re doing is a simple, one-time copy job, it is. But OS X doesn’t offer much help if you want to regularly keep files in sync. Sure, Time Machine handles backups, but even that has its limits. You might want to work on your local machine for speed’s sake, but then regularly copy your work over to a network drive, for example. Or maybe you have a set of working files that needs to be dumped to a USB stick at the end of every work day. GoodSync can handle both of those situations easily--and it can be used in place of Time Machine if Apple’s simple backup doesn’t quite meet your needs.
