Loading macOS Sierra on a newer Mac running Mojave or Catalina (Resolved)

[kazmac]

Hi everyone,

Can I load Sierra onto a newer Mac running Mojave or Catalina? (The later being hypothetical).

If I stick with Macs, I need Sierra to run on the new machine.

Do I use a virtual machine? Partition or something else?

And are there clear instructions somewhere?

I’ve never used VMs or partitions.

Thanks a lot.

Don’t think this is possible. The last version you can install is the version the Mac originally came with AFAIK.

Thanks for the response.

Yes, you can... but you cannot update it or install apps from Mac App Store, because... (see answer akash.nu)... but you can! I mean you can't install any app from Mac App Store. It will inform you are using wrong macOS version for you Mac. I also tried this trick with MacBook Air 2017. It comes with High Sierra on board. I installed Sierra. I did it, but cannot update it or install iWork apps from Mac App Store. So, theoretically you can, but it useless...
