[New-bugs-announce] [issue37861] Install fails on MacOS X 10.6 with python >= 3.7.1

[Clive Bruton]

New submission from Clive Bruton <clive at indx.co.uk>:

When attempting to install Python >= 3.7.1 on MacOS X 10.6 the installer fails with the message:

****
The operation couldn’t be completed. (com.apple.installer.pagecontroller error -1.)

Couldn't open "python-3.7.x-macosx10.6.pkg".
****

The installer runs without incident with the 3.7.0 installer.

Console reports (when "python-3.7.4-macosx10.6.pkg" is run):
