EA have released a hot fix patch to correct various issues created by the patch last Tuesday 16 April. One of the fixes is specifically for Mac users running 10.7.5 Lion:
Fixed an issue where Mac players on certain older versions of OS X were unable to launch the game. As a result, we rolled back a fix that was done for Mac players on 64-bit systems that eliminated a false error message which said, “The Sims 4” is not optimized for your Mac and needs to be updated.
The rolled back fix they are referring to is this one. Unfortunately we will start getting the error message again when launching the game after an OS update, or subsequent patch if they don’t fix it again in the next one. But I shouldn’t imagine this is anything to worry about, more an inconvenience than anything. It really is in EA’s interests to fix this error, otherwise the game will not load on the next version of macOS after Mojave.
This seems to be an emerging issue for Mac users since the June patch – the Sims 4 will not close properly when exiting out of the game. The game will appear to close but will still be running in the background. Using Force Quit does nothing and using Activity Monitor to quit processes doesn’t work either.
If you are suffering from this issue PLEASE post in this thread. The more info obtained the more likely we can come up with a fix.
EA have today made an update available for Mac users experiencing problems with the Sims 3. This hasn’t been released as a normal patch through the Launcher but as an update to Origin. They haven’t confirmed exactly what it fixes, only that it should “help with compatibility and stability issues”. Hopefully this means that all those with post-2013 Macs who have graphics cards which are not supported will now be able to play. The affected Macs are all listed here together with the workaround that some have managed to get working (hopefully that workaround won’t be necessary now).
The Origin update can be found here – https://eaassets-a.akamaihd.net/Origin-Client-Download/origin/forum/34349/Origin.dmg
Download it and give it a go. It may be a good idea to run the Origin reset tool first before you install it, I did. Bear in mind that this download is not the one you get if you download from the Origin website, this is a specific one that EA have released and provided the link for over at AHQ. After using it your Origin version should be 18.104.22.16859. My game certainly seems to be launching more quickly and quitting instantly rather than taking its time as it did before when I clicked on Quit Game. If you’re using the disc version of the game you will need to start running the digital version from Origin in order for this update to take effect. Full instructions here on how to do this (but you need to download Origin from the above link, not the one in the help page!).
Please, please, please take the time to post on the thread over on the official forums here, over on the stickied thread in the Mac section of AHQ here, or leave me a comment below. All feedback is really useful, good or bad.
This update is long overdue, I really hope it helps those who haven’t managed to play their games in years.
