Upgrading Mac OS stops Maya composite from working

Once you make an upgrade to the OS, in some situations the file access permission get changed thus stopping the application from launching.
Please do the following
Navigate to the var/temp folder and make sure you hav the proper permission to the Toxik folder

I got this on SL. You may still have a problem even if the permissions look correct. What I found works is if you simply delete the /var/tmp/toxik directory and then open up toxik. Toxik will see that the directory is missing and recreate it the way it likes it and then seems to work fine after that.
