Follow up question to [_Revisit the Hackintosh policy_][hackintosh]. Use case: * I create a [userscript] (in a [licenced] Windows or a Linux) and release it under GNU GPLv3 <http://www.gnu.org/licenses/gpl-3.0.html>. * I'd like to test the script with browser's available in macOS as well. * To be able to achieve this with the x86-based systems mentioned above (I do not own or have access to any Mac) I get a macOS ISO image and install macOS in a local VM. Does this comply with fair use's "[_public interest in the wider distribution and use of creative works_"](https://en.wikipedia.org/wiki/Fair_use)? If the answer is (more) "yes" are questions regarding such a use case tolerated here on SU?
