I am about to upgrade my Mac to 10.7.2. I will be looking out for this.
Did 10.7.2 do anything nasty to the Java installation? Check /Applications/Utilities/Java Preferences.app.
Does the Mathematica Kernel run by itself? The two methods of launching the kernel by itself are:
a) Launch a standalone kernel by Control-Clicking
the Mathematica application (.app) and selecting "Show Package Contents". In the folder that opens, open the Contents folder, then the MacOS folder. Double-click the MathKernel icon and a standalone kernel should launch.
b) From a Terminal window, enter the path to the kernel.
Typically this is /Applications/Mathematica.app/Contents/MacOS/MathKernel
Note that any spaces must be escaped with a backslash.
Or you can cd to the Contents/MacOS/ directory and run it with ./MathKernel
If the Kernel runs, evaluate
and copy&paste the long output into email - send it to email@example.com.
Also helpful would be
- the System Profile ( Apple menu - About this Mac, click "More Info...", in System Profiler click File menu - Save As to save the information in a file and send me that (Text format preferred))
- a screen shot of the whole MacDialog error window.
