Game Help:OSX Show Hidden Files

Starting from OSX Lion (10.7.x) onwards, certain files that are deemed "System Files" are hidden away now. This now applies to some of the files for Sims 3 as well (previously they were not hidden).

So, to do troubleshooting, you'd need to make these files visible first before you can delete them.

Enter the following commands in a Terminal window. You can also copy and paste them in. To open a Terminal Window: Finder -> Utilities -> Terminal.

To Unhide

defaults write com.apple.finder \AppleShowAllFiles -bool true
killall Finder

To hide

defaults write com.apple.finder \AppleShowAllFiles -bool false
killall Finder
