they say ‘’ Prebuilt _QGroundControl_ versions from 4.0 onwards are 64-bit only. It is possible to manually build 32 bit versions (this is not supported by the dev team)…‘’  
Since it is an open source software, if you can download the files and export them as 32 bit in qt creator, your problem may be solved. But I don’t know much.

Maybe a good start is to look at the CI builds which run on github. Here: [qgroundcontrol/macos\_release.yml at master · mavlink/qgroundcontrol · GitHub](https://github.com/mavlink/qgroundcontrol/blob/master/.github/workflows/macos_release.yml) you can see which version is used for the CI build.
