Python turtle module causes OS X to crash

Question

I'm working through Think Python chapter 4, where they tell you to type the following to see if you have the turtle module:

import turtle
bob = turtle.Turtle()

This is supposed to open a new window, but instead, it crashes my computer. I've seen it freeze my computer where I can't move the cursor or change windows, and I have to restart it. And I've also seen it close all my programs and re-open them.

I'm running Python 3.7 downloaded from Anaconda on a Macbook Air with Mojave version 10.14.6.

EDIT: When I run BenajahTX's suggestion below, I get this error message printed 16 times: CGSTrackingRegionSetIsEnabled returned CG error 268435459

Any clue what is causing this or how to fix it?

Answer 1

try and set the screen and mainloop

    window = turtle.Screen()
    window.setup(width,height)
    while True:
            window.update()
    window.mainloop()
