As part of our commitment to providing the best experience possible to our players, all of our 32-bit Mac games have integrated protection. This is to ensure that your experience is not only fun, but safe.
We are currently unable to provide the same protection or guarantee for 64-bit Mac apps or games. Until we can ensure the same safe and secure experience for our 64-bit operating system users, we will continue to release games designed for a 32-bit platform. Due to this, you would need to have an earlier macOS version in order to play your favorite games and future releases.
Our technical department is putting all their effort into researching various alternatives and new ways we might be able to implement the same protective safety measures in the future.
