I have a Macbook Pro 17, Core Duo 2.16GHZ with 2GB of RAM. I have noticed lately that whenever I do anything processor or disk intensive on the command line, that the GUI becomes totally unresponsive. I have tried to nice/renice the processes to +20, but this only helps a little. It seems like the GUI processes on the Mactels are scheduled with too low a priority to provide responsiveness? Thoughts? Solutions?
