Btw does anyone know how to test-install a newer OS other than with Mac OS' upgrade option burning through 6gb+ downloads supposedly also replacing the OS rather than installing it onto an external disk? I've got an unused old mini that's still on the OS it came with - way out of date. I even went to an Apple dealer to get Mojave onto an SSD drive last year, only to find out that the mini needs a firmware update for APFS that only comes with Mojave/Catalina, but I can't find a download option for only the firmware update so that I could boot from an external AFPS disk.

Can you not just back up the current SSD and repeatedly OTA it to the last supported version? That would be my solution.

Exactly what I had hoped to avoid. I only keep the Mac for cross-platform builds, site testing on Safari, and for hypothetically being able to open old 3D assets, but the old apps almost certainly won't work on newer Mac OS anyway.
