@daffive1 I'm not sure what you mean by "profiles," but yes, this should be possible. You can install the game on multiple devices using the same Origin account; just make sure you sign out on one computer before trying to play on the other.
If you're looking to play the same saves, you'll need to manually transfer them back and forth. There's no cloud saving for Sims 4. Saves are located in Documents\Electronic Arts\The Sims 4\saves, and the entire folder can be copied from one computer to another. The same goes for the Tray folder, which contains your saved household and builds. You can transfer the files using a USB stick or by uploading them to and downloading them from cloud storage.
In either case, it's a good idea to zip the files, or the folder they're in, before moving them. Both Windows and macOS can compress and extract .zip files; just right-click in either OS to see the option.
