Quite recently I got a Macbook pro, an early Christmas gift. So I download blockland (in .zip format not .dmg) it installs I click on the launcher.
The launcher loads and brings up the screen. The screen is white and is black where the launcher used to be. It closes after 1 or 2 seconds and an error pops up saying "Blockland has quit unexpectedly"
If I click it again, either the game will load and show up the title screen or just repeat the error again.
