Came here to say the same. I don’t know of any computational heavy engineering software available for the Mac. Unfortunately I’m stuck on Windows for all my software.
Well, the Apple Silicon Macs just arrived. If they are a compelling architecture for engineering software, then sooner or later a company will support them. Also, most Unix-based software should be rather easy portable, especially programs for computations which do not depend on a GUI.
There is a lot of engineering software which is only available on Unix and these days mostly on Linux, as it comes from times when Windows and PCs where not even remotely a consideration as a platform.
