Google Earth Mac Update
Although using the ‘Check for updates online’ function says there are no updates available, there has been an update of Google Earth for Mac. If you download Google Earth now you should receive version 3.1.0617.0 (beta) from Google’s servers.
Word on the street is that the new release features Entourage email support for sending Google Earth goodies to your friends. In addition, UFS and case-sensitive versions of HFS+ disks now work.
