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. ( 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):

Thanks for the report.  This problem was reported earlier for 3.7.3 in Issue36890.  As described there, I have now uploaded a copy of the old bundle-format installer dmg file for 3.7.4 that should work on 10.6.  See msg349787 there for details and comment there if that solution works for you.
