While a beta was spied sometime in November (and quickly whizzed around the web; personally I found a copy last week..), Google hasn't had a version of Google Earth for the Mac.
Until now.
No indication on what's improved since the beta (of course nobody was meant to see that..) though the warnings do say
- Google Earth is a broadband, 3D application that not all computers can run.
Which is vague enough, yes? Here's Google Earth for Mac OSX.
Then, if you're in the mood to worry, download the Avian Flu map (created by Declan Butler, a reporter for the science journal Nature). I'm not sure he's got the latest cases in Turkey there, but it's scary even without those.
