Re: MacBook Air: I accidentally deleted my sims 4 folder

How did you accidentally delete the folder? Normally, when you delete any file it will first go to the Trash-can on the right side of the Dock. Have you checked there or have you emptied you Trash already?

I also don't understand the screenshot you took. Where are you? Is that the Documents-folder? If that's where you store your game (in stead of the Applications-folder) that might be the reason it won't generate a new folder (?not sure tho?) - try moving it to the Applications-folder.
