Today I received the following email: "As a current MATLAB on the Mac customer, we wanted to inform you that the new 10.2 (Jaguar) release of Mac OS X introduces incompatibilities that prevent MATLAB 6.5 and other applications from running correctly. The MathWorks and Apple are working together to develop a patch that will enable MATLAB to operate
correctly with OS X version 10.2. We anticipate that this patch will be available in late September or early October. In the interim, we suggest that MATLAB users defer upgrading to 10.2 until this patch is available. We will contact you when it becomes available."

Nice to know. I discovered this myself, as written in my review of Matlab 6.5.
