Steps to reproduce this? Screenshots? Anything?

After starting the launcher, the play button is faded and inactive.

To reproduce:
Start the launcher.

Expected result:
The play button is clickable.

Actual result:
It is not. (See attachment)
The Status field shows "loading profiles and versions..."

Should be filed as a Launcher bug, could we get this moved?

Deleted all profiles and versions and reinstalled, and it works. Can the launcher not handle more than 20❓ versions?

I have this bug as well and it is bugging me. (no pun intended)
It would be nice to play minecraft soon. I also have a screen shot.

I am on a Mac. FYI
