I downloaded the Minecraft launcher and whlie it runs, as soon as I click "Play" it fails. In the development console I see:

Job 'Version & Libraries' finished successfully

When I watch the ~/Library/Application Support/minecraft/ folder, I can see folders and files being created as the console says they are being downloaded, but they immediately dissapear from the folder. I don't know of anything in base OSX that would cause this, but I'm not a Mac expert. Anyone seen something like this or have any suggestions?

Hi,

Please post the entire output of the Development Console in spoilers.

The board code says it is too long, here is everything from when I open the launcher, log in, click play, and get the error I'd seen before at the very end.

As I said, when all is done I look in the library/app support/minecraft folder and it is empty.

Any help or suggestions???
