I installed X-Plane 10 yesterday from the latest installer. When I try to run it (either X-Plane.app or X-Plane-32bit.app), OS X gives this error:
You can't open the application "X-Plane.app" because PowerPC applications are no longer supported.
What's going on? This worked fine on my other computer (2014 iMac 24"). This is on a 2015 MacBook Pro 15".
