What version of Xymon agent will compile/run on MAC OSX 10.5.8 🔗 link

Hi folks. It's been quiet on the list. Hope all is well.

I'm trying to find which version of the xymon agent will compile and run on an older MAC OS X 10.5.8 computer.

We tried the 4.3.7 build but it won't start on OSX 10.5.8

I was going to go download 4.3.3. but wanted to see if anyone knew before what version we should be starting with?

Thanks

Don K
