Hi, I had no problems with X-Plane (maybe some crash but very rarely) until the last month. I´ve updated my X-Plane from 10.4x to 10.45. I added more memory RAM too. I bought 4 gb in OWC website, so now I have 8 gb of memory RAM.
I have a OS X Yosemite v 10.10.15
But in the last weeks the simulator has become very unstable. I have crash flying over some areas but these crash are random. Of course I tested with basic sceneries and removing all the "suspect" addons and similar, so I can´t find the pattern or the reason about the crash. I have the rendering settings with the low option.
The log.txt after these crashes does not report anything like "application crashed!". But the system throws me and error, to send to Apple. Here is an example of part of the error (I have all the log saved in a file):

is problem of the Yosemite? is problem of my new RAM? (I don´t think so because all the system works fine with the new RAM).
Thanks
