Sorry for DP. I'm back, and after testing a bunch, I found that running the SOMA_NoSteam.app gave me this error:
Sounds unrelated, but at least it's an error message for once. Perhaps this is just a simple error that was overlooked for the latest beta?
Running the ModLauncher.app gives me a black square window. It looks like it functions the same as the game; runs but remains without any graphical feedback.
Also, I managed to get the hpl.log out properly this time. Looks to have very few errors, but hope it helps ya. Cheers!
