Everything You Want To Know About This Alert
By cleaning up 32-bit Apps/Gamings from macOS, Apple hopes that this alert will help gamers and game developers to raise a concern about the modern design of Mac apps/games. According to Apple: 'To ensure that the apps you purchase are as advanced as the Mac you run them on, all future Mac software will eventually be required to be 64-bit.'
- Q: Why am I seeing this '[GAME] is not optimized for your Mac' alert? A: Starting with macOS High Sierra 10.13.4, apps that have not been updated to use 64-bit processes produce a one-time alert when opened. This gives users advance notice that they are running 32-bit software/game, which will not be compatible with macOS in the future.
- Q: Can I keep playing my 32-bit games on my Mac? A: Yes, you may continue to play 32-bit games with your Mac today as this is just a reminder alert. This has no adverse effect on your data or your computer.
- Q: How do I check if my Steam game is 32-bit or 64-bit? A: On Apple menu > Choose About This Mac > Click the System Report button > Software > Applications. When you select an individual game, you will see a field titled '64-bit (Intel)'.
