Hello everyone, I am using this thread as I am experiencing the same issues since I have installed version 0.90. Here is my KSP Log from yesterday : https://www.dropbox.com/s/p13kmotq97qw9ch/KSP.log?dl=0 The game crashes a lot, I can't even play for more than 15min before it crashes. Also some issues into the game like when I right click on a module in flight to perform actions such as "crew reports", the little window does not disappear when I right click again. The map also when in flight is having some issues. I can't see Kerbin or even my ship or the solar system when going to the map. Maybe it's also a memory problem but I prefer letting you advise on that. I am using Macbook Air with OS X Yosemite 10.10 1.3 GHZ intel Core I5 RAM 4Go 1600 MHZ DDR3 Intel HD Graphics 5000 1536 Mo Thanks for your help
