I understand your request for installing Baldur's Gate III on your Mac for free.

The text provides several steps to install the game:

1. Go to the View Profile setting, set your Profile and Game Details to Public.

2. Download and sign-up for GeForce Now For Mac (free plan available).

3. Install BlueStacks on your PC or Mac (if you haven't already).

4. Search for Baldurs Gate Enhanced Edition in the Play Store and click to install.

However, I noticed that there might be some issues with installing the game. You mentioned an error message saying 'We've detected a data mismatch' after installation. This could be caused by unsupported mods, corrupt files, or unknown data, which may lead to crashes or other issues running the game.

If you're experiencing this issue, you can try reinstalling the game or checking for any corrupted files.

Additionally, it's worth noting that Baldur's Gate III is available in Early Access on PC and Mac, but there might be some differences between the two platforms. The game has been built using the new Divinity 4.0 engine and currently only supports PC and Mac.

The text also mentions that the game will be released on September 21 for Mac and other platforms, including PlayStation 5 and iPhone 15.

If you're looking for a free version of Baldur's Gate III, it seems like the game is only available through GeForce Now For Mac in its basic free plan. The free plan allows limited gameplay and has some restrictions compared to the premium subscription.

Let me know if you have any further questions or concerns about installing Baldur's Gate III on your Mac!
