Installing .package files on Macs (the new way)
We all know that the new patch is messing with our .sims3packs. However, there is an alternative. It is called 'Mods' or 'packages'. These mods can also add features or tweak stuff. You can get these by installing the 'framework'.
There have been several guides to do this before. But the Ambitions EP updated the way to make the framework, so the posts are outdated. The new version even comes with some support by EA. Even better, no transgaming or Bin folders to mess with!
First: Find Your Mods (Folder)
First, go to Documents/Electronic Arts/The Sims 3. create a folder called 'Mods'. Inside create a folder called 'Packages'.
Second: Get Your Resource(.cfg)
Second, get the *NEW* resource.cfg file (secondary click and download linked file: (It won't be nice if you get the old one.)
Open it in TextEdit and make sure the first number is 501, NOT 500.
If appeared resource.cfg.txt, rename it in finder by secondary-clicking on it and then clicking 'Get Info'. Then go to Name & Extension, take off the .txt part, press enter and click 'use .cfg'.
Place it in Documents/Electronic Arts/The Sims 3/Mods
Now install some CC.
Third: Where do I put the Files?
Place the .package files in Documents/Electronic Arts/The Sims 3/Mods/Packages.
Fourth: What Now?
Open up your game, if you downloaded a mod (something that tweaks the game, e.g. faster nectar making) it will pop up when you start the game. If it is an object, it will have a folder in the right-bottom corner in Buy Mode. This never happened in older versions of the framework.
Well, that's all folks!
