Installing Complete Collection EPs and SPs to legit game.

I purchased The Sims 3 in the Humble Bundle a few years ago. It came with Late Night, HE Loft Stuff, and I think Date Night, but I don't see it anywhere in the launcher or Origin. Anyways I just downloaded the Sims 3 Ultimate Collection what's my next step in installing the EPs and SPs? Also can I install the store content and limited edition content on your sites?

I don't know about digital versions, but I do know if you had the physical disk of the base game or any other games it will work just the same but you do need a hack the base game. So I'm assuming you need to download the torrent for all the other files, use a specialized UnRAR, which should be listed in the Mac Guide. And pretty much follow all the remaining steps to the guide to a T.

 Best Mac Guide
1. Download The Complete Sims 3 Torrent
2. Use the Mac Guide (Part 2-3)
3. Before the expansion packs: Can't update The Sims 3 to v1.67 fix. (Manual patch)
4. Install the expansion and stuff packs that you would want.
5. Use the Mac Guide (Part 4) and Ultimate Fix together in unison.
6. "Launch the game and... enjoy playing!"

@MrKimiko Do I need to create a bazillion disc images or can I just create 1 and move the installer I'm using to it?
