JOSM 19439 from dmg installation works on macos 10.15.8 but 19481 does not.

But when I start latest version using java -jar josm-latest.jar (19542) it still works fine.

BTW: yes, I know that macos Catalina is pretty old and not supported but I can help with testing it and very interested in support this JOSM in this OS.

Well. That's probably because I needed to increase the Java version for that download as I couldn't get the java21 version to (re-)build. And that again was caused by the fact, that ATM nearly all MacOS builds fail.

You can download other release files here: ​https://github.com/JOSM/josm/releases

As said - a lot of builds fail. Theoretically every release should have java 11, 21 and 25 versions.

Please report what works and what not, so others don't have to try again.

It would be very helpful if anybody can fix the issues with the MacOS builds.

I could start all available jar files without any problem:

• JOSM-macOS-java11-19542.jar - WORKS
• JOSM-macOS-java21-19542.jar - WORKS
• JOSM-macOS-java25-19542.jar - WORKS

Ok I got it.

cd /
cd Application
otool -l JOSM.app/Contents/MacOS/JOSM| grep minos

minos 11.0

Somewhere you increase min version type for MacOS 11 when building dmg file.

I think I remember a mail from GitHub, that the build systems now use a newer MacOs. Don't find any related mail thought.

Could you point me where I can read how to build dmg file myself?
Also I can help in running Github Actions locally if you need that kind of help.

Have a look at the GitHub actions in trunk/.github/workflows directory.
