Well, thank you all for the help... but the problem persists. I\'ve been playing since August, so I know how staging is supposed to work and how it used to work. But at this point, every ship that goes to the launch pad turns into a dice roll on how the staging works. Or not works, to be precise. I build a rocket and the first time its on the pad, the first stage launch ejects the SRB\'s. Bah! Back to the VAB and the icons show the SRB decouplers in their own separate stage ABOVE the lowest stage; which means the decouplers will fire when the lowermost stage is finished. At least that\'s the way it used to work and that\'s the way it does on the 2nd attempt (sometimes. Not always.) Randomly, it will work okay- I spend 15 minutes flying and then I screw up the moon orbit or something so I try again. Same ship, just hit relaunch, but now we\'re back to the dropped SRB\'s again. or the 3rd stage separates instead of dropping the empty tanks. Its maddening. I really do enjoy this game and it\'s a testament to it\'s appeal that I\'ve been playing it over and over again, despite the fact that it\'s pissed me off so much. I don\'t know if this is a problem just on the Mac or if it\'s not that big a deal to anybody else, but it ruins the game for me. I\'ve spent 4 hours playing tonight and I got two flights to orbit; the rest of the time was spent fixing staging problems. I really wish I could download 13.1 or even 12.x. for OSX, but since that\'s not showing up. I guess I\'ll wait for 14 and keep my fingers crossed. See you guys in March, hopefully.
