DOSBox full screen crashes OS X Lion
http://little418.com/2012/03/dosbox-full-screen-crashes-os-x-lion.html Old games are a lot of fun to play. DOSBox makes it easier than ever to blow the dust off of an old game, pop the floppy disks into a USB floppy disk drive, and game like it’s 1990 again. That was until I upgraded to Mac OS X 10.7 Lion. Suddenly, when I hit alt + enter DOSBox crashed :( Well if you’re running into that issue, here’s the fix! Install DOSBox and run it once. Exit, or if you're feeling mean hit alt + enter and let it crash out. Edit `~/Library/DOSBox 0.74 Preferences` (updating the version number to whatever version you have installed, of course) $ vi ~/Library/Preferences/DOSBox\ 0.74\ Preferences Scroll down to the `output` variable and updated it to use opengl. This switches the rendering engine to a less efficient but apparently more stable implementation. ... fullresolution=original windowresolution=original output=opengl #<--- change this line autolock=true sensitivity=100 ... Save the file and enjoy your favorite old school game!
