@Lemons927 Please move your entire Sims 3 folder out of Documents > Electronic Arts and onto your desktop. Open the launcher to create a new folder, then download one item (a fresh copy) and try to install it. Let me know whether it works.
If the launcher still freezes, please make sure iCloud isn't automatically syncing the contents of Documents with cloud storage. This guide is for a different issue, but the relevant settings are the same:

I did attempt what you suggested, Unfortunately It did not work. I do appreciate the time you put into helping me. Thank You.
@Lemons927 Try repairing the game in Origin: open your game library, right-click on the Sims 3 icon, and select Repair.
If that doesn't help, please try downloading and installing content in a new admin user account on your Mac. Don't link your Apple ID or anything else to the new user account, and don't import any settings. You should be able to sign into your current Origin account and open Sims 3 from there. When downloading store content, please use Firefox.
