Affects Version/s: 1.6.44
Fix Version/s: 1.6.48
Mac OS X 10.10.5 (14F27)
The new OS X launcher (with bundled Java runtime) will not start when a 1.9 snapshot game is opened. Previous game versions (tested 1.8 and 1.7) don’t cause this issue.
Replacing the Minecraft.app bundle with a clean-slate version from .dmg, running it (allow it to download runtime, etc) will clear the problem and launcher will start properly.
This happens with 1.6.44 and 1.6.45-dev versions.
Anytime launcher gets stuck, the following can be found in Console.app:
Also, trying to select `launcher` application in Minecraft.app bundle will crash the Finder, OS X’s default file manager. Just selecting it, not even trying to open.
