Could you share your save with me to test? Upload to a file sharing site and PM me the link to download.
Bluebellflora There's nothing to share. I just downloaded a game and started a new one with a random character to test productivity. Like an empty save. But I can share it with you if you need it
Yes please. The reason I ask is because I play on an M1 MacBook Air and M4 Max MacBook Pro and both are fine with my saves. Another good test you could try is setting up a new user account on your Mac and playing the save in that account. Launch the game in the new account and a new EA > TS4 folder will be created in Documents. Quit, copy your save from the saves folder in your usual Mac account by either copying it onto a USB or using the shared folder in Macintosh HD > Users > User account and then put it in the new saves folder. This would be an interesting test as it is a completely new user account with clean Library folder. When making the new user account keep it as simple as possible, you don't need to setup iCloud or anything.
