The Sims 3 Patch Download Unknown Error Occurred[Mac]

[ Edited ]

Hello Technical Geniuses! 


We have a brand new Macbook Air 13 inch, early 2015. We have just downloaded and installed The Sims 3 from MacGameStore. Unfortunately, to play the game you need to download the latest patch. So we clicked download patch...minutes later it says "Unknown Error Occurred". 


So we tried to open it and then got the message "unknown error occurred." Then we installed it again (overwriting the first install). Downloaded patch only to get "unknown error occurred" once more.


Anyone know an amazing fix?


Thanks for your help!


@Bluebellflora  please and thank you in advance

Manually patching is the best way. Instructions here


However, the game is not compatible on your Mac due to the graphics card not being supported in the game. You may be able to play just the base game but adding in EPs makes the matter worse. For full details please read the stickied thread relating to post-2013 Macs at the top of this forum.

Using CC/Mods is at your own risk, EA are not responsible for making the game compatible with 3rd party content, the creator is.

I managed to do a clean uninstall and install via your(?) instructions. Deleting all the Sims stuff from Library and then installing The Sims 3. I have managed to install EPs. The graphics play up a bit, as well as not being able to see the complete graphics options when changing them in-game...According to MacGameStore I had a compatible Graphics Card...Intel HD Graphics 6000...
