Following the release of the latest OS X Mavericks 10.9.2 build to developers earlier this week, Apple has released a new seed (build 13S4101b) of OS X Server 3.1 to developers today.

Apple seeded the previous build earlier this month as it inches closer to public release. 

To install OS X Server Preview, you need one of these computers: – 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.
