Hi, I'm on a Mac, have 1.14.4 Minecraft working fine.
Tried downloading the latest Forge Installer for 1.14.4, ran it, and about half way through it crashes.
JVM info: Oracle Corporation - 1.8.0_51 - 25.51-b03
Found java version 1.8.0_51
Added Lets Encrypt root certificates as additional trust
Considering minecraft client jar
Considering library net.minecraftforge:forge:1.14.4-28.0.9
