I understand that you're looking for information on 'The Dark Tower' and how to install it on Mac.

From what I gathered, there seems to be a board game app called 'Dark Tower Classic' available on the App Store. It's designed by Austin Boren and has received positive reviews from players. The game is a turn-based pass-and-play game for 1-4 players.

However, if you're looking to install 'The Dark Tower' on your Mac in the context of Stephen King's book series or the TV adaptation, I couldn't find any official information on how to do so. The books by Stephen King are not available as a digital download on Mac, and there doesn't seem to be an official way to install the game on Mac either.

However, you can try downloading 'The Dark Tower' for PC or Computer using an emulator software like Bluestacks or NoxPlayer. This will allow you to play the game on your Mac with Windows installed through boot camp or virtualization.

Here are the steps to download and install 'The Dark Tower' on PC:

1. Download the emulator software (Bluestacks or NoxPlayer) from their official websites.

2. Install the emulator software on your Mac.

3. Open the emulator and search for 'Dark Tower' in the Google Play Store.

4. Download and install the game.

5. Once installed, you can play the game on your Mac using the emulator.

Please note that this method requires a Windows operating system to be installed on your Mac, either through boot camp or virtualization.

I hope this information helps! If you have any further questions, feel free to ask.
