Thanks for your reply. I do not use Discord.
I downloaded the Minecraft "legacy launcher" (I had to show it how to find Java 1.8, since it automatically looks for 1.6. This video does a good job of showing how to do that: https://www.youtube.com/watch?v=vB9dP4ALsqw&t=99s
The "legacy launcher" got a bit father than the most recent Java edition launcher. Minecraft attempted to load, and then I kept getting a message that "Java has quit unexpectedly."
I'm wondering if the issue is that my Macbook Air (which I bought in 2012) does not meet the requirements to run Minecraft 1.13?
Thanks a lot for your response.
Is there any reason, given my computer’s specs, that Java would continually crash when I try to launch Minecraft 1.13 using the legacy launcher?
