Do you know which screen you were on when this happened?
You need to give more information on this issue before the developers know what the issue is

I think that’s a broken installation, maybe you should do a clean macOS install?

A bug report is NOT gonna do anything, try contacting mojang support

Isn’t this basic integer overflow? When the maximum integer value is exceeded, the bytes flip around and gets reset to the minimum integer value.

I doubt highly anyone has ever jumped more than 2 billion times in a single world

Oh, and by the way, with a 64-bit programming system:

1. The issue does not get solved, entering 2^64-1 and jumping once, will just do the same you described, but get the number set to -2^64

2. Optimization-wise is this a bad idea, because Minecraft will just consume a lot more RAM, because a long consumes more memory than an ìnt or a short
