Re: sims 4 expansion packs xbox to mac

@KoolNoodle669  Unfortunately, there's no way to share or transfer your content from the XBox version of Sims 4 to a PC install.  The two are considered different games in many ways, including the fact that you need to buy content for each separately.  I'm sure it's not what you want to hear, but all Sims 4 expansion packs, along with the Vampires game pack and Spooky Stuff  SP are currently 50% off in Origin.  The sale ends November 1st at 10 am U.S Pacific time.

As for installing mods, this is an excellent tutorial:

Please make sure that your mods and custom content are fully updated before installing.  Outdated content can cause all kinds of glitches and even corrupt your saves beyond repair.  Any decent mod creator will list an update history, and you can check it to confirm that the content is compatible with the current patch level.  It's also a good idea to back up your game folder before adding new content.  That way, if something goes wrong, you can just trash the new folder and put the old one back with no permanent harm done.
