I just installed tb on this new mac, and i realized every tori is naked without any items. Even when I do /dl alien, my items don't show. I'm on version 5.02

You probably have autodownload turned off try /opt autoupdate 1.

Or try changing the game settings from minimum or whatever u on to something else that should also help.

/opt obj 1/ /opt particles 1 also turns some items on.

Hope i could help you

You got effects turned on?

And I don't know how a mac works, but when you buy a normal new windows pc, you sometimes need to update some drivers. So uh, are the drivers updated?

Ohh I know why, when i open tb it says "You don't have write permissions for Toribash Folder. Some game features may not be available". I had this problem on my old mac but I forgot how to fix it.

You should probably go to your toribash folder (no idea where you should find it.)
Right click on the folder and somewhere under properties or something there should be an option to give it writing permissions.

But I know nothing about mac, so that's all advice I can give.

I fixed it, I just had to change some permissions from "Read only" to "Read & Write"
