@fbergmann After your fix, I have now get the normal Darvin version on Safari, and correct Intel version from Chrome.

fbergmann · 2023-10-26T06:45:46Z

@shoops the new download site does not quite work for me on Safari and Firefox (arm, Monterey):

it is fine on chrome though

fbergmann · 2023-10-26T06:50:11Z

the ua parser strings currently are:

safari

userAgentData:
undefined

UAParser:
{"ua":"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/16.6 Safari/605.1.15","browser":{"name":"Safari","version":"16.6","major":"16"},"engine":{"name":"WebKit","version":"605.1.15"},"os":{"name":"Mac OS","version":"10.15.7"},"device":{},"cpu":{}}

OS:
{"platform":"Mac OS","platformVersion":"10.15.7"}

Firefox

here it is even worse, as it is saying it would be an intel processor

userAgentData:
undefined

UAParser:
{"ua":"Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:98.0) Gecko/20100101 Firefox/98.0","browser":{"name":"Firefox","version":"98.0","major":"98"},"engine":{"name":"Gecko","version":"98.0"},"os":{"name":"Mac OS","version":"10.15"},"device":{},"cpu":{}}

OS:
{"platform":"Mac OS","platformVersion":"10.15"}

NOTE both are still confirming the platform to be macOS, so we should not see the source option for those.

fbergmann · 2023-10-26T07:05:33Z

Debugging the code, on Firefox I find:

score arm version = 20
score intel version = 20
score old Mac version = 24
score source package = 24

since the source package comes last it replaces (the also wrong old Mac version) and the source packages are offered.

fbergmann · 2023-10-26T07:14:51Z

On firefox intel + arm versions loose points because of the platformVersion not matching. The source version does not loose points because the platform version for it is set to undefined. I think by default the old Mac version should get a lower version to begin with. then it would be fine to have it offered alongside arm / intel version. Source should only be offered as default in case something else went wrong.

fbergmann · 2023-10-26T13:32:36Z

I've tried on another Mac (m2, arm), with a newer version of Chrome, and there detection of the OS also fails:

Google Chrom

userAgentData:
undefined

OS:
{"platform":"Mac OS","platformVersion":"10.15.7"}

shoops · 2023-10-26T14:06:22Z

I have fixed the scoring of source code. It will never outscore any installer.

fbergmann · 2023-10-26T14:10:50Z

@shoops that did fix the issue for chrome, however on Safari I'm still offered the Darwin version (which won't work on the arm / intel processors)

shoops · 2023-10-26T15:15:17Z

I just pushed a fix for version detection.

fbergmann · 2023-10-26T16:22:22Z

@shoops now I get on arm only twice the intel one offered

on chrome I now get the Darwin one.

shoops · 2023-10-26T16:37:10Z

I allowed _ in place of . in the version string.

shoops · 2023-10-26T17:25:21Z

I fixed the reference vs copy problem you are seeing above.

fbergmann · 2023-10-27T06:37:51Z

It is still not working on Chrome on the arm one (where it just suggests to download the ancient Darwin version). The issue is that when it reports arm, it does so as 'arm' not 'arm64', and it reports a platformVersion of 14.0.0. Here the detection result for the latest version:
