According to Apple Insider, a much anticipated test version of Google Earth for Mac OS X has begun limited circulation for testing purposes. I’m really glad to hear about this, because a lot of visually oriented people use Macs and so I can only imagine they will be even greater fans of Google Earth than most Windows users once they get their own native version of the program.
As soon as a version is available publicly, I will of course report it here at the Google Earth Blog. In the meantime, if you follow the link to Apple Insider above you will find some screenshots of the Mac Version to whet your appetite. Also, go to OgleEarth for all kinds of reviews and comments (Stefan has been eagerly anticipating this release for some time).
[EDIT: Another story here at the Unofficial Apple Weblog PLEASE NOTE that the test version circulating is a not-intended-for-public release which was leaked to the net. I'm sure Google will release an "official" beta test soon.]
