I am new to this forum but not new to X-Plane which I have been using for about one year. During this time, I have been running X-Plane ver. 10.40r3 without any problems on an OS/X Yosemite Mac. My copy of X-Plane was installed onto the Mac Desktop and I always ran it from there.
All was well until my 27" Mac's internal hard drive failed and the Apple Store replaced the faulty drive. They installed a fresh copy of OS/X Sierra (which had just been officially released only weeks earlier) onto the new drive. I then reinstalled all my apps from scratch - with the exception of X-Plane: I'd copied the X-Plane folder across from a Time Machine backup right back onto the the new, fresh Desktop. I ran X-Plane, only for a minute or so - it seemed to fire up correctly and I didn't encounter any immediate problems.
However, now, I have had a bit more time to play and fired it up again, this time choosing to do a quick 15 minute flight. At random times, usually a few minutes into the flight, the program crashed (X-Plane window disappeared and an OS/X crash report appeared, with the option of sending it to Apple (which I did)). I have repeated this several times now and I cannot fly for more than a few minutes without crashing. Also, during one attempt, the X-Plane window simply "froze" and I had to Force-quit the application.
I restarted my Mac and tried again, again receiving the same result: crashes after a few minutes.
To try to debug, did some testing. I took a screenshot of my current X-Plane settings and then reduced the graphic intensive settings. I tried running the program again, seeing the obvious lesser-quality visuals on screen - but the crashes persisted.
I also tried running the program in 32 bit mode (I usually use 64 bit) but I still encountered crashes.
I have attached to this post (in zipped format) my log.txt files (each of these were the files which existed after an x-plane crash) and also the Apple Crash-Report text files, in hope that someone may be able to detect the nature of the problem. There's also some screen shots of my About-This-Mac information.
So, here's the questions going through my head:
1. Is this an OS/X Sierra problem? All was working fine under Yosemite; I have changed nothing.
2. Should I delete the X-Plane folder and re-install X-Plane from scratch (not just copy the folder across from a backup)? If I do so, I would probably need to install the latest version of X-Plane, ver. 10.50r3 is it?
3. While I can of course install X-Plane ver 10.5x, I want to better understand if the problem I have is related to my version of OS/X (as opposed to the version of X-Plane). I was happy with X-Plane ver 10.40 as it worked well - I'm concerned that newer (different) probelms may be introduced with the newer X-Plane (ie. compatibility with additional scenery, etc).
Some guidance would be most appreciated.
