Ran into a problem after installing iOS8 on my iPod Touch 5G. Can no longer seem to do a wifi Sync with my iMac, either manually initiated or as part of automatic sync when charging. This worked fine with iOS7, but not now. It says "searching for the iMAC " and then eventually times out and quits the sync attempt. Syncing the iPod to the iMac with USB cable still works fine. Also, wifi syncing of my iPad Mini (still running iOS7) to the same iMac works normally. Only new variable is the iOS8 on the iPod. I'm running iTunes version 11.4 on the iMac under Lion. I believe this to be the latest iTunes version that is supposed to support iOS8. Anyone else seen this? Any ideas?? Thanks!
