How to I upgrade my OS from 10.11 to 10.12?
I have an older MacPro with OS 10.11. The software I'm trying to install is asking me to upgrade to 10.12. Where do I find this upgrade?

Hello Lacey8852! If you'd like to download macOS Sierra, you can download it here:
How to upgrade to macOS Sierra
Scroll down to step 4 where it says "If you still need macOS Sierra, use this App Store link: Get macOS Sierra. To download it, your Mac must be using macOS High Sierra or earlier."
Hope it helps!
