I might be able to debug during the weekend, but my main focus will be on back 
porting the changes in #41100 to the 3.8 branch (or at least parts of it).

All these failures point not on some details of appearance, but that the widget 
is not rendered at all.

[issue42507] test_ttk_guionly test failures on macOS with Tcl/Tk 8.6.10

[Ned Deily]

Ned Deily  added the comment:

OK, thanks for the clarification, Terry. Considering that our tkinter tests 
make assumptions about the underlying Tk widgets behavior, assumptions not 
necessarily shared by the Tk developers :), these kind of version-dependent 
failures are a risk of and shortcoming of having extensive tests like these. 
I'm not overly concerned about the failures other than it is not good to have 
failing tests.

Serihy: "Can I get a remote access to machine with macOS?" Sorry, that's 
difficult for me to provide right now; perhaps later.  Anyone else?

Terry J. Reedy  added the comment:

The test may be correctly detecting a change in widget behavior.  This is less 
surprising to me than some keypresses acting like two keypresses a millesecond 
apart.

Can you elaborate?

It might be the tk/tkinter build, not the tests, that is at fault.  That is my 
current conclusion for #42508 (regarding IDLE as a test).

I have no ideas. Try to add more calls of update() in these tests.

I tested on 3.9 with the backport of GH-23474 merged. The six failures are 
still there plus there is now an additional failure:

Try to test with 6cc2c419f6cf5ed336609ba01055e77d7c553e6d (PR-23474). All of 
failing tests were modified to make them passing on Windows, so I expect that 
this can help on macOS too (in most cases). If it does not help I will propose 
other changes for testing.

[issue42507] test_ttk_guionly test failures on macOS with Tcl/Tk 8.6.10

[Ned Deily]

New submission from Ned Deily :

As of 3.9.1rc1 (and coming soon to 3.10.x and 3.8.x), we now provide a new 
additional macOS universal2 installer variant that, for various reasons, 
provides a built-in version of Tcl/Tk 8.6.10, instead of 8.6.8 as has been 
provided with the 10.9 installer variant.  Using 8.6.10 on nacOS, six 
test_ttk_guionly tests fail while passing using 8.6.8 ib nacOS. Similar results 
were obtained when running the tests on either macOS 10.15.7 or 11.0.1. The 
failures:
