I've googled this for a while and searched the forums, but found nothing. Where am I supposed to find the Galaxy Editor? I'm on a Mac by the way. I've searched all of the Starcraft-related folders I know exist on my computer but still can't find it. Help is greatly appreciated.
I'm having the same problem, only on PC. Doesn't seem to be ant option in the B.net menus to get to it; as far as I know I don't even have it downloaded, and can't find a place to download it.
Ah don't worry, even this forum's admin had trouble finding it. You'll find what you need here: http://www.starcraft2forum.org/forums/showthread.php?t=13833
Thanks for the help everyone! However I recently found out that the Galaxy Editor for Mac won't be available until the game is released. I was planning on messing with the Galaxy Editor and playing around with one of those Build Order Tester Maps on there during the downtime, but I guess I'll just have to get a life for once. D:
