Uninstall your most recent EP then download and reinstall the digital version from Origin. Instructions here.
I bought The Sims 3 a few years ago on a PC, but now i have a mac. It works just fine on my dads computer which is also a mac, but for some reason when i try to play on my Macbook air it says "No game disk found! Please insert The Sims 3 game disk before proceeding" My problem is that i never owned a game disk. i purchased the game through Origin from the start. I have heard that i simply installed the wrong update but i don't know how to uninstall the update and reinstall the correct one. If anyone can help i'd love to get some advice!
Moved your post to this Disc Error stickied thread. You'll find the links and instructions you need in the opening post. Links to the manual patch updates are also in my signature.
