For those wanting to try it for themselves, we recently released a preview of our full stack for Mac (containing both OmniSciDB as well as our Immerse frontend for interactive visual analytics), available for free here: https://www.omnisci.com/mac-preview. This is a bit of an experiment for us, so we'd love your feedback! Note that the Mac preview doesn't yet have the scalable rendering capabilities our platform is known for, but stay tuned.
You can also install the open source version of OmniSciDB, either via tar/deb/rpm/Docker for Linux (https://www.omnisci.com/platform/downloads/open-source) or by following the build instructions for Mac in our git repo: https://github.com/omnisci/omniscidb (hopefully will have standalone builds for Mac up soon). You can also run a Dockerized version on your Mac, but as a disclaimer the performance, particularly around storage access, lags a bare metal install.
