[issue36890] python-3.7.3-macosx10.6.pkg verification error on macOS 10.6 Snow Leopard

Ned Deily  added the comment:

Beginning in 2020, we have stopped providing the 10.6+ installer variant for 
macOS since all evidence that we have is that it was used very little and there 
are a grower number of problems with trying to use it on very old systems, as 
evidenced in this issue.  Since there has been no feedback yet about not 
providing the 10.6+ installer variant, I am closing this issue as not to be 
fixed. (We continue to provide the 10.9 64-bit-only installer variant.)  By the 
way, this does not mean we are intentionally removing or breaking support for 
building and running on 10.6 systems.  It's just that we are no longer 
providing pre-built binaries for them.

Ned Deily  added the comment:

Sorry, I did not get around to trying to repackage 3.7.3 and, since then, 3.7.4 
has been released and someone else has now run into this problem on 10.6.  As 
my Python time is very limited at the moment, rather than trying to find a 
build solution to make signed flat packages (.pkg) files work on 10.6 again, I 
have uploaded a copy of the old-style bundle installer disk image file (.dmg) 
for 3.7.4 which is still produced as an artifact of the build process for our 
installers so the Python files it installs are identical to those installed by 
the 10.6 pkg install.  Bundle-format installer packages no longer work on 
modern versions of macOS but should still be OK for 10.6.  Please test and let 
me know if it works for you for 10.6 and I'll add it to the 3.7.4 release page. 
 However, as Ronald noted, be aware that we plan to no longer provide the 10.6 
variant installers for Python 3.8.x.

The dmg installer and its PGP signature file are downloadable here:

Ronald Oussoren  added the comment:

We generally don't drop support for OS versions in patch releases for Python. 
The 3.8 installer will require macOS 10.9, as does the default x86-64 installer 
for 3.7.

S. J. Cunningham  added the comment:

Apple's decision to support or not support their products is driven by Apple's 
business considerations and is not binding on anyone else.  Many people 
continue to use earlier versions because of dependence on applications which do 
not run on later versions and/or because later versions do not offer sufficient 
benefits to justify the cost of upgrading.  I don't know on what basis the 
Python organization makes these decisions but I hope it is more than simply 
following Apple's decisions.

Hi,

In fact, there is another question, MacOS X Snow Leopard is not supported since 
2014, do we need to continue to generate the package for this version?

Ned Deily  added the comment:

Thank you for the report.  It appears that macOS installer packages produced on 
current versions of macOS can no longer be successfully opened by the macOS 
10.6 (Snow Leopard) system installer.  This used to work.  Perhaps a 
certificate or something else has changed.  I can try repackaging the Python 
installer package using an older macOS tool chain but I probably will not be 
able to get to this for a few days because of travel.
