First, yes, you can use the unstable version of it works for you. Just be aware that we might change stuff in the development cycle such that you would need to keep up with the development.
Second, it is weird that you get asked for gcc-12, while we have switched to gcc-13 and also fallback to clang in the unstable version. Without deeper inspection of the commands and logs you have this is hard to debug
Third: last week we changed the compilation infrastructure to meson instead of make, so I guess it is best to start from scratch anyways.
Also because you can compile with R2023b (native as well as Intel) now. The official package for apple silicon will take another week I think, but we are almost there.
So the short term solution: please compile dynare using these instructions (which are soon in the master branch as well) and report back if it worked for you to compile the unstable version:
There is only one major issue: please don’t use the latest Xcode command line tools 15.0, but downgrade to 14.3.1. (you can find instructions online how to get the installation package or write me an email so I can sent it to you).
