I also was experiencing crashes on Mac OS 10.14.2 Mojave after the intial reentry of license credentials for SkyMax Pro 4.7. X-Plane 11.30 would crash every time after I installed Skymax 4.7. Contrary to the other email I received citing that Real Weather Connector was updated to 1.1 and that all you had to do was install SkyMaxx Pro 4.7 to get the RWC 1.1, that is incorrect, as it never installs. I even tried removing RWC 1.0 and SMP 4.7 does not install a new RWC 1.1. Launching X-Plane 11.30 with SMP 4.7 installed always crashes X-Plane, whether or not I leave the old RWC 1.0 in place and configure the system to manual weather, or if I remove RWC 1.0 entirely. X-Plane does not generate a crash log because the application crashes, but Mac OS does generate a crash report, which I have attached. I had to revert back to former version SMP 4.6 and RWC 1.0 to be able to fly again.
