Game running choppy (Macbook pro)

[kattiq]

Hey guys!

So I recently just started back playing the Sims 4 (took a few months off. ) and this is my first post here in a loooong time!

I have a MacBook Pro (13-inch, Mid 2010) - yes I know this is not an optimal gaming computer...
2.4 GHz Intel Core 2 Duo
4 GB 1067 MHz DDR3
NVIDIA GeForce 320M 256 MB
OS version El Capitan 10.11.3

When I first started playing it ran like a dream on medium settings (and I was totally fine with that) with Get to Work, 3 stuff packs and some CC installed. (This comp even played Sims 3 pretty well too)

Recently, when I started the game back up it's choppy, the music goes in and out and tasks go on very slowly.
FPS run about 8-10.

Things I've tried:
I've turned off origin in game, have most settings on low (objects and sims on medium), lowered resolution..
I've tried window mode and full screen- no difference
No CC and a few CC- no difference
I actually reinstalled my OS and cleared out a ton of memory
Cleared what cache there was and replaced the Sims 4 folder on several occasions
Reinstalled and repaired game.

The only thing that has happened in the months in between play times is:
I downloaded El Capitan, updated to most recent patches and also bought Get Together expansion.

I have ordered a memory upgrade (from 4gb to 8gb) to see if that will help the situation?
I am assuming its the new OS and the expansion pack that is making it really slow now.
I feel like I've literally tried everything. So if anyone else has any more suggestions, please help a girl out. Ha!

You may be onto something. As I've heard there are problems with El Captain operating system and Sims 4. Sometimes it works and sometimes it doesn't. - Link below on the OS and Sims 4 as well some other links for Mac users, just in case you want to have a read.

Bumping up the system memory will help. But it won't solve all of the problem.

Okay thanks, I am looking through the links now! I may have a back up that is still with Yosemite that I could try to revert back too since I don't really care much for this new OS anyways. But I'd have to go back and re-delete all the files I have gotten rid of now  :|

[kattiq]

So..one day later after finding a backup I had from a year ago.. I reverted back to that backup because it still had the Yosemite OS. I can officially RULE OUT that El Capitan was the issue. 
I began playing finally, after downloading and installing all the games again. It ran fine for like maybe 5 minutes and then the dreaded choppy game play resurfaced. It was worse on community lots but still pretty bad at my sims house too.
So, only thing I can think of is that it is unfortunately the Get Together expansion that is causing the issues.
Hopefully, the upgraded memory will help when I can get it installed. *fingers crossed*

Thank you for the update. I had wondered if going back to a previous operating system might help.  I'm sorry you're having a hard time with the game.

[kattiq]

Yeah, I was hoping it would be the key since it ran fine before on that OS.
Oh well I'm still going to try this last thing. I love the Sims too much to give up just yet. Ha!
