Do we or can we have Mac OS slaves in Jenkins?

Hello, Part of the Ruby SDK uses native code that needs to be compiled during installation of the gem. The Ruby SDK is a requirement of ManageIQ, and many ManageIQ developers/users use Mac OS. In the past I had some issues with this environment, as the C compiler there behaves in an slightly different way than GCC. Those issues were discovered only when the SDK was already released. To avoid that I would like to have Jenkins jobs building/testing the SDK for Mac OS. Is that possible? Do we have Mac OS slaves? If not, can we have them?
