Steam Steam not initalizing on Mac OS


Trying to get my steam build for OSX mac to work. I'm seeing this error in the console.

Failed to copy Steam DLL - '/Users/arichardson/Documents/Development/space-game/sdk/redistributable_bin/osx32/libsteam_api.dylib' - SDK not installed properly?
followed by a sting of attempts to access this file:

Error: Failed to load libsteam_api.dylib from  /Users/Shared/GameMakerStudio2/Cache/runtimes/runtime- Runner.app/Contents/MacOS/libsteam_api.dylib
dlerror:dlopen(/Users/Shared/GameMakerStudio2/Cache/runtimes/runtime- Runner.app/Contents/MacOS/libsteam_api.dylib, 1): image not found
Error: Failed to load libsteam_api.dylib: dlopen(/Users/arichardson/Library/Application Support/com.yoyogames.macyoyorunner/game/assets/libsteam_api.dylib, 1): no suitable image found.  Did find:

Failed LoadSteamLib() call: Error loading libsteam_api.dylib
SteamInit failed: Error loading libsteam_api.dylib
I've placed the 'sdk' for steam and referenced it in the project in the steam preferences. Windows version works fine but Mac one does not.

Still having this issue. Tried downloading SDK v 1.42 which GMS2 docs say to use that version specifically but no dice. I'm curious if completely reinstalling GMS2 would have any effect or not...
