I’m curious how they plan to do continuous integration. The Apple hardware-only clause of the macOS SDK license agreement really crimps the options for CI, especially for open source projects with limited budget. Travis is a godsend, but there are startup latency and capacity issues there even in the paid tier. Apple has made major contributions to open source, as evidenced by FoundationDB here, LLVM, WebKit, and other projects. But they no longer make servers, and the fallback — Mac mini — is on life support, which puts projects and service providers who need to treat macOS as a first-class target in a real bind. Even something limited like the IE Edge and Visual Studio images Microsoft provides would be a huge boost.
