Hi, I recently updated to Mavericks on my iMac 2010. Since the update the Superdrive on the iMac doesn't appear to be working. It won't accept disks at all and you can't hear it make noise when turning on the mac. Here's what I've done & know. the drive IS showing up in System profiler and Disk Utility. I have reset the PRAM I have re-installed Mavericks Still no life from the drive. Any help or advice would be greatly appreciated. Thanks!
