Good day, Prior to the 1.2 update my computer, specs of: Macbook pro OS: 10.10.5 Processor: 2.26 GHz Intel Core 2 Duo Memory: 8 GB 1067 MHz DDR3 and Graphics Card: NVIDIA GeForce 9400M 256 MB, ran Starbound at a decent rate and only became sluggish near high particle areas such as the portal to the Ruin. However once the 1.2 update came out I went down to 1-2 frames thus making the game unplayable. I waited patiently for an update to fix this and when I saw others stating that Update 1.2.1 had fixed their fps issues I was estatic. Sadly I now have another issue I can load Starbound by browsing local files and using the launcher in directory Library/Applicationsupport/Steam/steamapps/common/Starbound/osx but launching via steam immediately causes the game to unexpectedly quit. Here is what the log states. [20:18:52.747] [Info] Root: Preparing Root... [20:18:52.749] [Info] Root: Done preparing Root.
