X-Plane 10.20beta 64-bit version has been out for a while now. I have downloaded it several times to try (on macOS), but every time, the application would quit unexpectedly within a second of launching, making it completely unusable. It was quite frustrating. I wonder if any friends have encountered the same issue?

I also tried sending the error report back to the developer, but it was like sending a message into a void with no reply. Helplessly, I had to reinstall the stable version 10.11 and continue using it.

If you know how to solve this problem, please let me know. Thanks a lot.

Postscript: This problem has been basically solved. For the specific method, please refer to this blog post.
