I was looking for Mac-compatible syncing apps for the “How to Sync iTunes on Multiple Computers” post and Russell tipped me off to a great one.
I use the creatively named SyncTwoFolders for syncing on my mac.
I checked it out and it works great. I successfully synced both my iTunes folder and my wife’s (across the network) with my backup folder on an external hard drive. Here’s how to do it:
Step 1: Download the Program – Go here, click “Download Now,” then select either the “Mac Intel” link , or the “Mac PPC” (Power PC, for older Macs like the Powerbook) link next to the “SyncTwoFolders” icon. After the file downloads, unzip and drag the .app file to your Applications folder.
Step 2: Set Up Your Sync – Open the program and select your “Source” folder and your “Target” folder. For an iTunes sync, the source would be your iTunes music folder on the primary computer and the target will be the secondary computer, whether across the network or on an external hard drive.
Selecting your “Synchronization Mode” can be a bit confusing because of the terms used, so I’ll break them down for you. “Reciprocal” will only look at files that are in both folders, replacing any older file with the newer one. No files will be deleted in this mode. “Source up Target” will do the same thing as “Reciprocal,” but also copy any files from the source file that are not in the target folder (i.e. if you add new songs to your library). No files will be deleted in this mode either. “Source on Target” does the same thing as “Source up Target,” but also deletes any files from the target folder that are no longer found in the source folder (i.e. if you delete any songs from your library).
Select your preferred “Synchronization Mode” (I use “Source on Target” so I have an exact copy) and add any additional filters you want. If you hover over any of the options, a box will appear describing that option. If you want a test run to see what files will be affected without actually moving anything around, click “Simulation.” Click the right-most checkbox to see the log.
Step 3: Run Your Sync – Make sure “Simulation” is unchecked and click “Synchronize.” Then, just sit back and watch your files fly across the magical tubes. Now run to the kitchen sink and pour yourself an ice cold glass of Mother Nature’s life juice, because you just synced two folders.
I muted my sound because it copies each file individually and my computer was chiming non-stop. My only real complaint is that you can’t schedule regular syncs, but for a free app, that’s definitely not a deal-breaker.
