cant build 10.15 and 11 support together

[Simon Smith]

im trying to identify why i cant buildle an app for both 10.15 and 11 using only Mac 11?

ive updated our github actions to use Mac 11 but when building a bundle it loses support for 10.15
and wont run unless the end user has Mac 11 installed

if i change our github actions to use Mac 10.15, it works no problem?

our build command is simply

astilectron-bundler -ldflags -X:${REPO}/pkg/version.Version=${VERSION},${REPO}/pkg/version.Revision=${REVISION},${REPO}/pkg/version.Branch=${BRANCH},${REPO}/pkg/version.BuildUser=${BUILDUSER},${REPO}/pkg/version.BuildDate=${BUILDTIME}

have you tried setting flags in bundler.json?

Mine look like:

{
    "app_name": "MyApp",
    "version_electron" : "8.2.5",
    "icon_path_darwin": "resources/icon.icns",
    "icon_path_linux": "resources/icon-64x64.png",
    "icon_path_windows": "resources/icon.ico",
    "ldflags":{"linkmode":["internal"]},
    "environments": [
	{"arch" : "amd64",
	 "os"   : "linux"},
	{"arch" : "arm",
	 "os"   : "linux"},
	{"arch" : "386",
	 "os"   : "linux"},
	{"arch" : "386",
	 "os"   : "windows"},
	{"arch" : "amd64", 
	 "os"   : "darwin",
	 "env"  : {
	     "CGO_ENABLED": "1",
             "CGO_CFLAGS": "-mmacosx-version-min=10.11",
             "CGO_LDFLAGS": "-mmacosx-version-min=10.11"
	 }}
  ]
}
