I was wondering if there is any key sequence to exit a graphical user interface (GUI) does not work, and preferably display a terminal window or something. You know, for those times when you are pretty sure that the kernel still works, but the GUI is not just being sensitive.
In Windows, you can ctrl-alt-del and execute commands with the menu option "new task" or “End task”. Is there any way to do something similar in OS X ??
