Question: Can't use Maple for Mac ("Kernel Connection N/A)"

Hello!

Since a few weeks i use Mac OS X, I downloaded the accordingly maple version from my campus server and installed it. I can start the program, but when I enter a simple instruction like plotting x^2, I get a little progress window with the headline "Kernel Connection Not Available", in the window there is: "Waiting for kernel connection" with a status bar and a Cancel-Button. The status bar runs through until about 60% and then it doesn't go on.

Can you tell me, what the problem is? I'm a student from germany, so please excuse my English. I'm not a computer expert and also my knowledge about Mac is still very developable.

If the problem has still been solved here, please excuse my post and refer me that thread...

Thank you!

Kai
