I got a new laptop (MacBook Pro 16, 32GB) so I had to download R and R studio and all packages again. Now when I run a mixed effects model with brms I get the following notice:
Compiling Stan program…
sh: clang++ -mmacosx-version-min=10.13: command not found
And it takes a very long time to start sampling. Any ideas how this can be fixed? Thanks.
