Yes, it was fine under high Sierra for a long time. Then, out of the blue, it crashed twice in a short period of time. I posted about it below and Juan said that updating to Mojave would fix the issue (whatever it is/was). I don't know if the latest crash is the same problem or not.

I don't know if this could be an issue, but I noticed that after updating, the 'auto graphics switching' option was turned back on. I just turned it off. I know that option can be an issue with TSX, so maybe it makes a difference here....
