macOS thread - updated to include 10.15 Catalina

Trying to run Sim3 base game on Sierra for the first time. Program stalls everytime.  Is there a way to know when a fix is ready to be downloaded? I mean, aside from trying to install updates everyday. Here is my info:

• Mac specs: MacBook Air, Late 2010, 2.13 GHz Intel Core 2 Duo, 4 GB 1067 MHz DDR3, NVIDIA GeForce 320M 256 MB (model, year, processor, RAM, graphics)
• Have you upgraded from a previous version of OS X or have you done a fresh install? Upgraded from prev version OS X to Sierra
• Which game - Sims 3 from disc
• A detailed description of the issue(s): installed Sims 3 then installed the updated. Sims crashed during initial installation of updated. I closed it and reopened then installed updates again. That time it worked. From there I tried to play the game (using the Play button on the Sims home screen). The screen changes to the larger game window that just says Sims (no buttons) and hangs there. I left it for 5 minutes with no progress. Had to quit the program through the Mac.  Tried to load it again and the game play window didn’t appear this time but it still hung. Cancelled it though my computer.  Tried restarting the computer and opening it but it didn’t help.
• Which Expansion/Game/Stuff Packs you have installed: none so far. I have the supernatural expansion pack but am waiting to install until the main version works.
