Dear Rui: Did you by any chance install an old ppc version of X11 onto an intel machine? If so, it might be running via Rosetta, which is an emulator provided for transition, but could account for lousy performance. OS X 10.6 comes with X11 installed by default, so you might have clobbered it with something else if you "installed X11". If that is the case, simply reinstalling the X11 on the 10.6 install disk should fix your problem.
Also, run the command file /whatever/path/to/bin/coot-real If it returns Mach-O executable ppc then you need to use an intel-compatible coot for best performance.
