I just downloaded this mod last night, and I have some problems with it. Keep in mind that I own a Mac computer with 4gb of RAM and an onboard Intel HD 4000 video card. I installed the mod without a hitch, and I put a map sat dish onto my craft. I launched it, and my game started to freeze when I got to 6,000m above Kerbin. It would freeze for a few seconds, then continue for a few, freeze, continue, freeze, and so on, until my game was unplayable. This problem is very consistent, too; with three reinstalls of the mod and two reinstalls of the game, it continues to freeze at 6,000m. I tried to fly another craft without any Map Sat parts, and it ran just fine. The craft I used that had map sat was nearly identical to the other craft. Please help me, for I would like to play my game with mods for once.
