I'm unable to install both the precompiled binary and the brew cask versions of CHIRP on macOS 12.4. The issues do not seem to be covered by this similar question composed by a macOS 10.x user.

After getting the binary passed security the app just immediately crashes anytime you attempt to run it. I have an Apple cash report available if that's helpful. For the brew version, it's currently choking on a reference to pygtk which can't be found.

  • $\begingroup$ @DavidHoelzer What, are they too good to use StackExchange? Jk. I noticed that there were a lot of CHIRP questions and it's considered on-topic but yes I will open a GitHub issue or something if we can't get it answered here. $\endgroup$

  • $\begingroup$ Sure, feel free to ask CHIRP questions... but this really seems to be more of a "I can't get this to install on my system," which isn't really a radio question. It's just my opinion. Folks might be able to help you here, but the project owners seem better positioned. $\endgroup$

    $\begingroup$ @DavidHoelzer Most likely I will self-answer. It's a dependency issue, probably pygtk isn't ready for newer macOS. I will dig into it after work. $\endgroup$

You must install the deprecated Python Version 2.7

You can find the installer here: https://www.python.org/ftp/python/2.7.18/python-2.7.18-macosx10.9.pkg

I tested this on an Intel Mac running Monterey 12.4

  • $\begingroup$ @Hack-R, I empathasize withyou and the chirp crew hopefuly will upgrade. That said, Mac end users really need a solution now. I don't know Python well enough to offer a pull request update to their repo. $\endgroup$ Oct 13, 2022 at 16:42
