Barrier is no longer in development. Check out Deskflow (upstream) or Input Leap (fork).

https://github.com/deskflow/deskflow
https://github.com/input-leap/input-leap

If this is still an issue in those projects, we would appreciate a cross-post of this issue.

Hi, thanks for your reply.
Unfortunately, deskflow isn't available in macports for 10.6.8 and Input-Leap always fails to build.

I'll keep tinkering.

Nothing is stoping anyone from making a pr on deskflow (or macports) to add it. You are not gonna get updates from input-leap or barrier they are very much unmaintained at this point.

Edit:
10.6 is a bit old and deskflow would not be able to support it anyway since minimum for Qt6 iirc is mac os 12
