macOS thread - updated to include 10.15 Catalina

I updated to Sierra Version 10.13.2 last week and the Sims 4 now has serious lag issues to the point the game is unplayable.

- iMac 21.5-inch, Late 2012, Processor 2.9 GHz Intel Core i5, Memory 8 GB 1600 MHz DDR3, Graphics NVIDIA GeForce GT 650M 512 MB

- Upgraded from previous OS X, was working fine

- Sims 4

- Very sluggish/slow response to commands (lagging)

- All Expansion packs (including Cats & Dogs), All game packs (except Vampires), most stuff packs (except Fitness Stuff, Bowling Night Stuff, Movie Stuff, Spooky Stuff, Kids Room Stuff)

Thanks in advance!
