macOS thread - updated to include 10.15 Catalina

I have a Macbook Air (13-inch, mid-2012), 1.8 GHz Intel Core i5 processor, 4 GB 1600 MHz DDR3   RAM, Intel HD Graphics 4000 1536 MB graphics

I have upgraded from a previous version of macOS, quite an old version I believe I can't remember it though.

I have the Sims 4

When I go to Origin everything seems fine up until the point where i try to play the Sims 4. At first it takes awhile to load but when it does it only takes me to a black screen for like a few seconds and then the black screen disappears and all I can see is my desktop and all the things I left open before playing the Sims. It also says that I'm still using the Sims 4 but after a few seconds the game says that the "application is not responding" and so I force quit the game. And everything seems normal again.
