Mac OS 10.11.6 Can't Load 1.18 Release Candidates

I'm not sure how many other people are experiencing this, but attempting to boot up any of the 1.18 release candidates crashes the game instantly. I've attached the launcher log. I'm running this on Mac OS 10.11.6, and I do not know which version of Java I have installed. I do not know if this is an issue with MC Java, the MC Launcher, Java, or my computer.
