– iMac (Mid 2007 or newer)
– MacBook (Late 2008 Aluminum, or Early 2009 or newer)
– MacBook Pro (Mid/Late 2007 or newer)
– MacBook Air (Late 2008 or newer)
– Mac mini (Early 2009 or newer)
– Mac Pro (Early 2008 or newer)
– Xserve (Early 2009)

Your Mac needs:
– OS X Mavericks 10.9.2
– At least 2 GB of RAM
– At least 10 GB of available disk space (50 GB if you wish to use Caching Server)

Installation Instructions

Install OS X Server 3.1 Preview 13S4101b on a computer running OS X Mavericks 10.9.2.

This preview supports upgrade and migrations from OS X Snow Leopard Server 10.6.8 and newer to OS X Server 3.1 Preview 13S4101b.

Noteworthy Change and Areas to Test

– Internet Access pane (accessible via the Server pane of the app) correctly displays services available over the internet.
– General bug fixes

Known Issues

– In Wiki Server, creating new wikis with “All Logged In Users” permissions set to “no access” results in “read only” permissions being set instead.
– In Xsan, changing the Network Settings in Server App while configuring Xsan fails with: “An error occurred while configuring the BMC interface”. The workaround is to apply the settings again.
– In Xcode Server, automated logic tests run in the simulator may fail with an error similar to: “Test target [test name] encountered an error (Test process exited with code -1).”
– In Caching Server following a migration OS X Snow Leopard Server to OS X Server 3.1 Preview 13S4101b, the data directory is not created. The workaround is to turn the Caching Server service on.
