Re: saved files from onedrive to Macbook
@majabajaib Yes, you can download your OneDrive data and use it on your Mac. Sims 4 user content, the files inside Documents > Electronic Arts > The Sims 4, works equally well in Windows and macOS.
The best practice is to launch the game once on your Mac to make sure it's working, then transfer the files to your Sims 4 folder. It's best to transfer the files, i.e. the files inside Tray and not the entire Tray folder, rather than the folders they're in.
Edit: For anyone else wondering how to do this, just go to onedrive.com and sign in with your Microsoft ID and password. You'll be able to download your OneDrive data from there.
