Looks like Palette doesn't yet work in the OSX Mojave Beta 2 (18A314h). It's being recognized in the USB Device Tree as the "Palette Multi-function Device", however the apps (2 and beta) don't recognize it and the core stays dark (other than the lit up frame).
I am very aware that functionality can't be expected in a OSX beta, however I wanted to bring this topic up. Hope you can prioritize this soon(ish) as some users (me included) are starting to use the beta for various testing reasons.
