Posting here for interested parties and in case someone searches for OS X here.
I completed the annual updates to the OS X Installer which now supports installation of FreeSWITCH 1.6 on OS X 10.11, 10.10 and 10.9. If you install FreeSWITCH on a Mac this is the way to go. It installs everything from Xcode to Testing FreeSWITCH. You can select the production or master version of FreeSWITCH installed from source. Logs of major steps are created on the Desktop.
The major wiki update is going back to a single page with most instructions since the 3 supported OS X’s have almost identical installation steps. Some of the changes are listed below the pages.
