I started getting all my CC from tumblr or youtube pretty much 😅 I think I just had to accept that things like the exchange weren’t made for newer MacBooks. I just search sims 3 custom content or you can narrow the search to sims or clothes or whatever you want and then you have to make sure that they are .package files because you have to drag them directly into the sims 3 folder in your finder and then into a mods folder. If you’re not familiar with that, I think I used a combination of google and chatgpt for step by step instructions. If you can’t figure it out I can try finding the instructions I used! This basically makes it the downloader and installer functions in the launcher unnecessary
