Google Earth for Mac leaked

An unofficial version of Google Earth for Mac was leaked on December 9. As you would expect of a program that is not yet ready for release, there are bugs, unimplemented menu items and window management issues so use it with care. But the program looks and feels fantastic!

Graphics are reportedly based on open GL rendering; the transitions and zooming certainly are very smooth.
System Requirements: Google Earth Mac beta: Mac OS X 10.4 or later. The download of this build of Google Earth for Mac is 12.6 MB.

This copy was not intended for release so you will not find it on the Google website yet.
