Matlab freeze on mac

Hi,

I have a problem with my matlab (R2012a on Mac OS X 10.8.4). Since today, it was working before and I didn't installed anything in-between, when I open matlab I have the window, "busy", "initializing" and "ready"... but I cannot click anywhere. If I move the window then it gets completely grey. When I open a m-file, I can see it, but the same, I cannot click anywhere and if I move the window it gets grey and that's it!

Do someone have an idea to solve this problem or already had this problem?

All other programs are running well (R, mendeley, TeX...), just Matlab!

thanks a lot

NEW EDIT, Problem fixed!

It was a Java problem,

I found the solution in this post: http://www.mathworks.com/matlabcentral/answers/79489-java-1-6-0_51-breaks-matlab-2012b-and-below

A new update of java from last week breaks matlab version prior to R2013a, It is necessary to install the java update from here: http://support.apple.com/kb/DL1572 which solve the problem.

edit: Using the Console to get the error message I have the following lines in the log when I launch matlab:

01/07/13 14:06:58,699 MATLAB_maci64[1601]: This process is attempting to exclude an item from Time Machine by path without administrator privileges. This is not supported. 01/07/13 14:06:58,700 MATLAB_maci64[1601]: This process is attempting to exclude an item from Time Machine by path without administrator privileges. This is not supported. 01/07/13 14:06:58,701 MATLAB_maci64[1601]: This process is attempting to exclude an item from Time Machine by path without administrator privileges. This is not supported. ... (the same about 70 times)

So I shut off the time machine but it don't change anything. I tried also to launch Matlab from the terminal with "sudo" before to have administrator rights, then I get:

01/07/13 14:13:45,036 CVMServer[121]: Check-in to the service com.apple.cvmsCompAgent_x86_64 failed. This is likely because you have either unloaded the job or the MachService has the ResetAtClose attribute specified in the launchd.plist. If present, this attribute should be removed.

in the console, but still, nothing changed, still cannot do anything with matlab.

when I launch matlab with -nodesktop from the terminal it works, no error message in the console and I can interact with matlab:

Yet, I still have no clue why the desktop freeze!!!!

Hi Pieter,

You've probably unearthed the answer since this post. In case you haven't, and for future search engine passengers, there was a recent Java update for OS X 10.8.4 that appears to be causing very similar problems. See this MathWorks thread. Hope that helps!
