It keeps saying class out of date.
It's not even a crash:

I recently updated Java to the recommended version, and I have the same problem.

@MinecraftGuy800 on Macs, you have to install jdk (Java development kit) 8 to have minecraft mods work. Without jdk8, apple's shipped jre (Java runtime environment) overrides the oracle one because of how mc is started. Find a guide to install jdk8 on a Mac.

Your version of Java is outdated.
