[New-bugs-announce] [issue42507] test_ttk_guionly test failures on macOS with Tcl/Tk 8.6.10

[Ned Deily]

New submission from Ned Deily <nad at python.org>:

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:
