I made sure that I am launching 1.14.2, but it's still crashing on me. Somehow on my other Mac (MacBook Pro 15-inch, Early 2011, 2.5 GHz Intel Core i7), it runs just fine, but I don't get it why Minecraft would crash on me on the latest version.
Proof that 1.14.2 still crashes on me (had to upload this on Google Drive because it's too large to upload here): https://drive.google.com/open?id=144Hc2R7IgSfmT72-uLDCSL_TTgbODzjv
What I meant to say was that I made the pandas teleport to me using the command /tp. When I load the world up, I believe they were on the chunk borders since I trapped the pandas so they couldn’t escape.
