Hi, I got a new MBA last weekend and transferred the library from my old MBP to it, by copying the Music/iTunes folder. The library contains only apps for my iPhone and iPad, no music. After transferring and starting iTunes the MBA felt sluggish. A look in Activity Monitor shows CPU usage is > 100%. Even after a couple of hours, CPU activity doesn't go down. Is there anyway I can hunt down this issue ? Is it looking for something ? I'm not using any plugins, just the basic iTunes setup with a copied library. Thanks !
