The new release of OSX Mavericks has caused some problems for OpenRA (see #3992, #3993). We are investigating these issues and hope to upload fixed packages before the 2v2 C&C tournament this weekend.

We have also released a new playtest that fixes the targeting bug present in playtest-20131019. If you have been enjoying the global chat lobby and new RA balance, then you should head over to the downloads page to grab it!
