(Mac) java.lang.UnsatisfiedLinkError: Failed to locate library: liblwjgl.dylib

[BillBodkin]

Using the sample code from NPM on a Mac creates this error when launching the game (1.14 vanilla). The native files are being downloaded by the launcher into minecraft/natives/1.14

Have tried specifying the path using -Djava.library.path and also tried using chmod to make the files executable.

I have pasted the full error below:

// Why is it breaking :(

For anyone having the same issue, thanks to Hanro50#5000 we tested using the Java version bundled with the official Minecraft launcher and found it to work.

(I think) The issue was that the version of Java it was using before was ARM but the files it was trying to load were not. The Java version included in the official launcher was x86_64
