1. Does CatSim work on an Apple M1/M2/M3 computer?

• The pre-compiled lib_catsim_macos.so is for Apple chip (M4 Max). It should work on a MacBook with the Apple M1, M2, M3 chips. If you have the older x86_64 (Intel CPU) chip on your MacBook, you will need to recompile the library on your computer locally. You can do so by using the MakeMacOS makefile in the gecatsim/clib_build directory. Remove the "-msse" option to the gcc command when compiling on your M1/M2/M3 computer. Make sure you are using the "gcc" compiler and not the default "clang" compiler on the Mac OS.

2. I'm having issues using this with Anaconda on an MacBook.

• If you're on an newer MacOS computer that uses the M1 chip, make sure that your Anaconda installation is for the M1 and not x86_64. Anaconda added support for M1 only in 2022. https://www.anaconda.com/blog/new-release-anaconda-distribution-now-supporting-m1
