Follow up question to Revisit the Hackintosh policy.

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"?

If the answer is (more) "yes" are questions regarding such a use case tolerated here on SU?
