Just a heads up, that post is several years old.

 

Optifine for 1.14.2 doesn't have a stable release yet, it only has a prerelease which isn't finished yet.

 

You're going to be best off just waiting for an official stable release to come out, which likely will follow the release of Minecraft Forge for 1.14+.

 

Currently the team behind Forge is working on putting together a release for 1.14, however it's a huge amount of work for them to do. They're also changing how they handle things to hopefully make development much easier and faster for the future.
