I noticed that minecraft indev was added to the list of version files using the new "Time machine" feature. When i opened it up, it was perfectly fine. But a couple seconds in the game, it blackscreened. I looked at the main menu and it said that there was 3MB of ram allocated, even though i have it set it to 1333MB.
P.S. this is probably a duplicate bug, which i do not care about.
Old versions are not supported as stated by the popup you get when trying to launch them.
