Hello, I have used SPM5 on my Intel MacBook Pro with no problems at all...just tried installing SPM8 and I can get the GUI up, but Matlab crashes as soon as I try to do anything, even just display a single image. I have Mac OS X 10.4.11 (w/ X11 installed) and Matlab 7.5 (2007b). Does anyone have advice on what to try, or what could be the source of the problem here? Thanks a lot!
