I recently upgraded my 2008 iMac from SL to Mavericks. Since then, iTunes no longer automatically syncs over Wi-Fi every time I launch it or power up my iPad 1. When I connect the iPad to the iMac using a USB cable, iTunes automatically launches and syncs. In the iPad section of iTunes, I unchecked and rechecked the boxes for auto launch and auto sync. But the next time I tried over Wi-Fi, nothing happened. Any suggestions? Thanks.
