What's the commercial usage limitation? Is that specifically for virtualization of OSX to prevent offering a "Mac On Demand" by not letting you run the OS itself?
> (iii) to install, use and run up to two (2) additional copies or instances of the Apple Software within virtual operating system environments on each Mac Computer you own or control that is already running the Apple Software, for purposes of: (a) software development; (b) testing during software development; (c) using macOS Server; or (d) personal, non-commercial use.
[ed: i guess you mean running os x server is an alternative to "non commercial use" - I agree with that reading. The option for nc use seems like a nod to not completely make experimentation and creative development/research entirely illegal.]
