how to let fyne app run on a lower osx version ?

[JackySmith]

Hi,I have a problem that delay my work for a few days
when i package app on 10.15, it can not run on 10.11
when i package app on 10.11, it can run on 10.11+ include 10.15
but i cannot run it on osx lower than 10.11
it there a resolution let app run on 10.7?

This might partly be dependent on the Go version that you are using. I know for example that Go 1.15 dropped support for El Capitan. Are you using different Go versions?

[JackySmith]

on osx10.11, I use go1.13.15 ,that's ok
but if I use go1.12.17, it can not run after go build on osx10.11
well, osx10.7 only support go1.11
so I cannot find a solution

This seems like it could be a duplicate of #886, you may need to specify some macos parameters when packaging for older systems, particularly:

export CGO_CFLAGS=-mmacosx-version-min=10.11
export CGO_LDFLAGS=-mmacosx-version-min=10.11

We will get this addressed in 1.4.2 following the duplicate #886 issue

Fix is in PR #1612, should be merged for 1.4.2 release next week

Unfortunately Apple stopped supporting this platform 6 years ago, so it is unlikely you can build new apps for it.
We support back to 10.11 which most computers sold in the last 12 years should be able to run.

@JackySmith maybe you can update your old OSX Lion computer to a newer version of OS X to get support?

I don’t think it would be possible to make them run on OSX 10.7. Go 1.12 (the currently oldest version for compiling fyne) supports only OSX 10.10 and Go 1.15 (latest stable release of Go) dropped supports only OSX 10.12 and later.
