On OS X Catalina, running 'solve' in DifferentialEquations causes crash

Thanks, that is good to know. I haven’t used Julia in a few months but this experience of it not “just working” was something new. In regards to your advice, I added VectorizationBase, v.0.12.12, but even after adding the package to my code I get the crash on the solve() call. Here’s my versioninfo():

We very recently updated to use these new vectorization tools since it gave some pretty massive accelerations on small stiff ODEs (<200) over OpenBLAS and MKL (without lots of tweaking). So it’s somewhat new, and it means we have to iron out a few things on a few CPUs, but the experience is so much better (10x faster small stiff ODEs than OpenBLAS for users who don’t manually change thread counts for example) that I want to just keep pushing this and fix any issues that come up, so thanks for reporting the issue because this is how the brave new world of performance will become stable.
