Hi
OS X builds are now available via the usual channel.
The wiki pages have been updated to reference both the 10.6 and 10.9 (target) versions.
When in doubt, choose the highest version that does not exceed your OS X version level.
Examples: If you are still on OS X 10.8, choose the 10.6 version. If you are on OS X 10.9, choose the 10.9 version. If you are on OS X 10.10, choose the 10.9 version.
Windows builds will hopefully follow later today.
