I thought it may be a good idea if we had an El Capitan thread where people can report any issues they've encountered in their game or Origin since updating. This should be separate from the other El Capitan threads as they relate to the Developer and Public Beta releases which are available before official release and can be unstable and buggy.
If you have encountered an issue since updating please can you report it here. Hopefully everything will be fine but if there are any niggles we can gather the info in one place and compare models so it makes it easier for EA to collect information. For an up to date list of known issues please see the second post in this thread here. Please provide the following:
Mac specs. (model, year, processor, RAM, graphics)
Have you upgraded from a previous version of OS X or have you done a fresh install?
Which Expansion/Game/Stuff Packs you have installed
If you are having issues, please also post the following information from your Config.log (or post a screenshot here). This can be found in Documents > Electronic Arts > The Sims 4 > Config.log. Just double click the file and it will open in Console. Scroll up to near the top and you will see the info:
