How to build a Go app that can cross-macOS-version?

Here is my recently created macOS app: https://github.com/evillt/macmineable-release
and here is my facing issue: https://github.com/evillt/macmineable-release/issues/18

I built the app on my machine it can run normally on any BigSur device, even M1 devices, but can not run on Catalina(10.15).

So what I want is to build a version that can run on multi-macOS-version with a single app.

Huge thanks for any suggestions!

update

My device is MacBook Pro 2015, Intel I5 chip, Big Sur 11.5.2.

I build this app on my device, it can run normally on:

• My device
• MacBook 12-inch Big Sur 11.0
• Other M1 devices (Big Sur 11.0 or above)

But can not run on MacBook Pro Intel I7 Catalina 10.15.7. The issue here.

That is all I know.

You need to change the CC compile go uses during your builds.

 go env CC

 clang

which most likely uses the version in /usr/bin/clang

if you have Xcode installed - or really just the Command Line Tools you can see a variety of versions for the last few major releases e.g.:

$ find  /Library/Developer/CommandLineTools -name clang

/Library/Developer/CommandLineTools/usr/bin/clang
/Library/Developer/CommandLineTools/usr/lib/clang
/Library/Developer/CommandLineTools/usr/lib/swift/clang
/Library/Developer/CommandLineTools/SDKs/MacOSX11.0.sdk/System/Library/PrivateFrameworks/GPUCompiler.framework/Versions/A/lib/clang
/Library/Developer/CommandLineTools/SDKs/MacOSX11.0.sdk/System/Library/Frameworks/OpenCL.framework/Versions/A/lib/clang
/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/PrivateFrameworks/GPUCompiler.framework/Versions/A/lib/clang
/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/OpenCL.framework/Versions/A/lib/clang
/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/System/Library/PrivateFrameworks/GPUCompiler.framework/Versions/A/lib/clang
/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/System/Library/Frameworks/OpenCL.framework/Versions/A/lib/clang

so to build against an older SDK like MaxOSX10.15, set CC to the explicit version you need for your go build like so:

CC=/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/System/Library/Frameworks/OpenCL.framework/Versions/A/lib/clang go build

I have good experience building as a Unix executable and packaging as a Mac app, by using the instructions manual at
https://medium.com/@mattholt/packaging-a-go-application-for-macos-f7084b00f6b5

build Unix exec file
go build -o bin/{program} {program}

Packaging the application on macOS (Big Sur) and installing it on macOS (High Sierra) was successful.
