Mac Support

[Rossi]

Over the course of FL having 15,000 people or more join the server, I’m sure at least one of the used a Mac

I would properly say it’s not your Mac and just might be something wrong with your stuff in general or perhaps it’s FL

I’ve heard of so many people having this problem before and they have been windows computers

I think it’s just a  coincidence of having a Mac?      I’m not sure but I recommend checking if you have space left on your computer because that could cause it to crash or maybe your subscription amount is too much and over loads your system. I know it sounds un likely, but it’s possible

He only has around 10 workshop items on steam and has lots of storage left, i don't know...

I'm not too sure then. Perhaps try uninstalling all of FL's content, open your game and make sure they're gone, then close the game and reinstall Garry's mod. That may just work or it may not, but looking at your situation, you don't have many options. Worth a shot!
