Aloha everyone, I recently purchased the 27" iMac i5 and everything is working perfectly, with one exception. I host my iTunes and iPhoto libraries on an external drive, so that I can take everything with me while traveling. I was able to use both iTunes and iPhoto on my two primary Macs, my old iMac and my MacBook Pro with no issues, as they were both pointed to the appropriate libraries on the external drive. Enter the new iMac ... I held down the option key and pointed iTunes (on the new iMac) to the iTunes library on my external drive, after which I plugged in my iPhone. Initially, before plugging in my iPhone, all content appeared as it did on my MacBook Pro. Once my iPhone was plugged in, however, I was presented with a window stating that my iPhone was unable to be synced. On subsequent attempts, my iPhone was either not recognized, or I was presented with that same window. Yesterday, I decided to attempt a sync with my MacBook Pro, so I ejected the external drive from my new iMac, mounted it on my MacBook Pro, fired up iTunes, and attempted an iPhone sync, with worked perfectly! I am forced, at this time, to use my MacBook Pro to sync my daily podcasts and such, instead of my new iMac. My new iMac has the latest version of iTunes, so this is a rather vexing issue for me at this time. I am considering conducting a clean install of Snow Leopard, using the install discs, but I may end up with the same result. The only other option, if a clean install is indeed the correct course of action, is to use my Snow Leopard disc for the install, but that would install Mac OS X 10.6.0, not 10.6.2, which may not be possible. Has anyone else experienced this issue, and if so, how was it resolved? I have Thanksgiving weekend to sort this out, and as a former Windows user, have no qualms with respect to conducting a "nuke and burn", but I was also wondering if any other options could be pursued. I appreciate and welcome any and all suggestions and/or comments on this issue.
