MacOS build 10.13 on 10.15

Hi,

I’m trying to build a MacOS program.

I defined both value :
CMAKE_OSX_DEPLOYMENT_TARGET: 10.13
OSX_MIN_VERSION: 10.13

The build works perfecly
But when I run this on 10.13 it’s not working. Do you know how we can build 10.13 compatible on 10.15 ?

the build is here : https://github.com/goshiz/haven-offshore/actions/runs/135954686

Thanks !

Unfortunately, macos-10.13 is not available:

Sorry about that!

The best option would be to use a self-hosted runner: https://help.github.com/en/actions/hosting-your-own-runners
