Kind of the same setup for me. Primarily Java work on a 6 core laptop. Between Chrome absurd RAM/cpu usage, IntelliJ, Gradle, Weblogic memory usage is just super high and cpu is not so little either at times even without build. Add anything extra I'm running for diagnostic, performance tuning and things are very troublesome. And Mac doesn't seem to handle such pressure as gracefully as Linux (though I'm not 100% sure).
