I'm a bit new to Lightwave Layout, is there a simple or easy way to save poses for my character for later use? Im running LW 2020 on a Mac running High Sierra
You could try Legato.
I don't know about Mac compatibility but it handles Poses and Animations.
From the same Layout timeline, or from an external LWS file that has the Legato plugin applied.

First you must identify each pose and/or animation by defining markers and/or regions.
After that you're able to Clone, Move, TimeStretch, Bake, etc.
You may add each marker or region to the Library, in the negative frame range.
Select a frame range, then, MMB-drag to Clone, RMB-drag to Move a pose/animation.
Or select a target frame (range), select a marker or region from the listbox, then
press button 'T' to Transfer a pose/animation.
Note: LScript support has been stopped after LW2020.
Anno 2020 it's still a Work In Progress but many features should still work surprisingly well (at least on my PC).
