Looks like a bad copy of Overboost went out for Mac OSX, due to not being in a .dmg, which introduced issues with permissions on the executable. It wouldn’t have shown up when running it via Finder, but you would see this via Terminal:
LSOpenURLsWithRole() failed with error – 10810 for the file /Users/*removed*/Downloads/overboost_alpha0_osx/bin/OSX_10.9/overboost.app.
There’s a dmg.gz now available that should resolve that problem:
Overboost Alpha 0 For Mac OSX (DMG.GZ)
Once it’s unzipped, Finder drops the .DMG extension. Rename the file and add the .DMG extension to the end, then mount the image and play the game.
Let me know if you encounter any issues, and thanks again for trying out my game! 🙂
