I had this issue on a Macbook Air that I was playing with today. The Bluetooth mouse had stopped working, and after checking the batteries etc, decided it must be an issue on the Mac itself. I had a look around and tried to find a fix but sadly, just like any old trusty Windows system, a reboot was the simple fix for this problem. Mac users tout about how stable the platform is, but in reality it is just as stable, or unstable as Windows can be. I also have to run updates on the Mac’s around the place just as often as the Windows boxes..
I had this problem with one of our creative staff at work today.
The creatives all run Mac’s with either VMware Fusion or Parrallels for Mac so that they can run a Windows XP guest OS with Office 2007. The main reason for this is that Outlook 2007 integrates better with our Exchange 2007 servers than Entourage.
I started researching the issue on the Vmware website, and found lots of references to the deleting of .vmss files and .nvram files.
I tried these, but it would still crash Fusion when I tried to start the guest OS.
I attempted to create a new guest using the existing hard disk .vmdk file, but this didn’t work either.
I then disabled the optical drive on the guest settings, and voila, it started!
This seems to be an issue with only the Macbook Air, and only if you have removed the superdrive, but not told Fusion about it.
