When I was getting ready to upgrade my MacBook to Snow Leopard with a format and fresh install, I began by backing up my files to an external hard drive. I had accumulated hundreds of documents, photos, music tracks, etc., and wanted everything backed-up – not just via Time Machine – but also as raw files and folders.
One of the folders I made sure to backup was the Music > iTunes folder, which contains not only my music, videos and podcasts, but also the configuration information that lets my iPhone 3GS know that it’s partnered with that specific iTunes library. Apple only allows an iPhone to sync with one iTunes library at a time (bummer), so failure to backup and restore the iTunes folder on your Mac after a fresh OS install will result in having to wipe and restore your iPhone before you can sync with iTunes again.
Shortly after I began the upgrade process, an email came in from an iPhone Edition reader asking why he couldn’t sync his iPhone 3G with his new iMac running Snow Leopard. After I replied with the bad news, I began writing a series of tutorials for iPhone Edition laying out the steps for backing up and restoring iTunes library information on a new or re-installed Mac or PC.
I’ve just completed the section on Moving Your iPhone to a New Mac, and should have PC to PC, Mac to PC and PC to Mac sections completed in the next few days. If you’re moving to a new Mac, or performing a fresh install of the new Mac OS, have a read and tell me what you think.
