After using Parallels on a MB 10.5.3, the MacOS icon has disappeared. It does not show on the desktop or in finder. I have repaired permissions, verified drive (booting from MacOS X disk) created a new account, and all messages say the disk is fine and everything is ok. In disk utility it is shown as mounted at / (with a line under it, which I think is correct). The icon for my Windows partition is fine, but I cannot se what the problem is caused by. Any ideas where the problem lies?? I searched the forums but saw no similar posts.
