My wife and I share a Imac snow leopard based computer; We noticed an error message pop up on a sync stating that certain music files could not be found. I recently used Onxy utility to clean my imac because I was getting a lot of spinning beachballs-more than usual. I used the basic functions in the Onyx. things seemed to run better. Whatever the case, I figured I would just do a restore to an earlier date on Itunes; She syncs at least weekly; why are these syncs not in the restore drop down window? There's some from back in March. Mine are up to date......ideas? Suggestions?
