Bug/Issue Won't open from steam

Hey guys,

I just bought Stardew Valley for my MBP, but I can't open it. When I open it through steam, it says running, then syncing, then nothing. It never opens a seperate window. I've tryed every single thing that people suggest to fix this problem, but none have worked.

People say to check there error logs to find the problem and when I did, I found an error I hadn't seen online. So here's the error log:

Code:

So it has somthing to do with a missing localtime file? BTW: I have a 2011 MBP running macOS version 10.13.1. It has 16GB of memory and a 2.7 GHz intel Core i7.

I really hope someone can help me out, I really want to play!

Thanks a ton!
