The only license you need to accept to use this software is Apache 2, so I’m not sure where you’re getting the idea that there’s an Apple hardware restriction.
The question is not about where FoundationDB can run in general. Sorry if that was unclear.
The question is about (public?) continuous integration testing for changes to FDB against macOS specifically, eg for pull-requests (for example, to allow contributors to make changes targeting other platforms without needing to own a mac for local tests).
The good news is that FDB has a fairly opaque platform abstraction, and deterministic simulation tests for everything above it, so the vast majority of continuous testing in terms of CPU cycles can be run on Linux.
The only thing that really needs to run on a Mac are tests for changes to the build or packaging system, or to the MacOS implementation of the platform layer. My sense is those changes are pretty rare.
I don’t know whether the FDB team has an official recommendation for MacOS CI. I’d recommend posting a question on the forums: http://forums.foundationdb.org
I already set that up, it installs the binary for FoundationDB then runs the tests for our Rust client on mac. No reason why they couldn't do the same for FoundationDB, but I bet they have something in house.
