Im new to programming and to the Mac OS so I apologize for the dumb question in advance. Ive been semi-successful running X11 although sometimes it takes 2 command N clicks to get the terminal window to stay open. After running a bit of code, and closing the program or the window or both, I cant seem to re-open a terminal window, and upon reboot, have to hold the power button to force a shutdown, each time this happens. I tried the terminal window (native to the OSX) but that doesnt seem to launch either once this error occurs. Does anyone have any experience with this??
