Manual Tk/Tcl UI tester does not work on macOS

[ben-spiller]

Describe the bug The manual tester seems to hang the Python process with a warning: 2019-03-29 11:12:32.438 Python[2909:33227] WARNING: NSWindow drag regions should only be invalidated on the Main Thread! This will throw an exception in the future.

then a hang in manualTester.stop.

To Reproduce Fibonacci_test_005 demonstrates this. In 1.4 we will skip this test until fixed.

Affected version(s)

• Python version(s): 3.7 (probably all versions)
• PySys version(s): 1.2, 1.3, 1.4 (probably earlier versions, possibly forever)
• Operating System(s): macOS 12.3

Not sure if manual tester has ever worked on macOS?
