MAC steam version wouldn't start

Problem: Besiege keeps showing white screen but leaves the dock there after starting the game on MAC.
Operating System: macOS Mojave 10.14.4
System Specs: MacBook Pro (15-inch, 2017), CPU 3.1 GHz Intel Core i7, RAM 16 GB , GPU Radeon Pro 560 4 GB and Intel HD Graphics 630 1536 MB
Game Version: the version on steam

Also, I went through the Besiege bundle in steam folder but I couldn't find the output_log.txt file in Besiege/Content/Data or anywhere else in the bundle.
I also tried doing
chmod -R 755 Library/Application\ Support/Steam/steamapps/common/Besiege/
but it wouldn't work as well.

It's a different location on OsX: ~/Library/Logs/Unity/Player.log
Have you tried reinstalling the game?

I couldn't find any solutions, internet mentions it might be based on what graphics card you have. Could possibly also be a bug in unity that's fixed in a newer version than what Besiege uses.

You can try asking on the official Besiege discord, in case somebody on there has had a similar problem and knows how to fix it.
