AppleInsider is reporting, and showing screen shots, of a version of Google Earth for the Mac. While still in development, AI reports that a pre-release version has been making the rounds overseas for about a month. The Mac version will reportedly have a good deal of customization, allowing for user customization of colors and some of the other features. As of now there is no release date, but AI does have some screenshots of the software. As always, Mac rumors sites are known to be wrong, but one thing in AI's favor on this is the fact that Google has promised to develop a Mac version for a while.
