Every time I start Mathematica 11.1, or restart a session after
Quit, it takes about 20 seconds on my rMBP 2014 MacOS X 10.10 for the kernel to start up. I just figured out (by switching off my wifi) that this annoying wait time is due to the kernel checking the internet at startup. Without wifi, the kernel launches quickly.
Why is the Mathematica 11.1 kernel checking the internet each time I launch the kernel? and is there an option to switch it off? It's annoying to have to turn off my wifi before starting/restarting Mathematica.
