On Apple Silicon Macs you can’t install an older version of macOS but you can install an M1/M2 ARM chip compatible version of Windows instead. On Intel Macs you can then run an older 32 bit compatible version of macOS such as macOS Mojave or run Windows on your Mac (if the app or game you want to play also works on Windows of course). The only way to play 32 bit games or run 32 bit apps on macOS Sonoma, Ventura, Monterey, Big Sur, Catalina or M-series Macs is to install a virtual environment.

In the last column on the right, you can see whether the game or application is 32 or 64 bit Intel compatible.In the left menu bar, scroll down to Software > Applications.Go to the Apple logo in the top left of your screen and select About This Mac > System Report.Here’s how to check whether the game or app you want to use is 32 or 64-bit compatible. The same applies to some music production or DJ software for Mac that have lots of 32 bit plugins that will no longer work in the latest versions of macOS or on an M1/M2 Mac. The most notable program is Microsoft Office 2011 but there are also others like MetaTrader, Adobe CS5 and CS6, Aperture, older versions of iTunes, iBooks, iPhoto and some Steam games which are still 32-bit only. However, the problem for some Mac users is there are still some older applications and games that are still 32-bit only.

If you try to run a 32 bit-app in Sonoma, Ventura, Monterey, Big Sur, Catalina or an M-series Mac, you’ll get the following “App is not optimized for your Mac and needs to be updated” error message:

The latest Apple Silicon M1 chip Macs and M2 Macs are also incompatible with 32-bit games or apps and if you’re trying to run 32-bit an M1 Mac, we recommend you skip to the section on 32 bit games and apps on M1 & M2 Macs. You can only install 64-bit apps on Sonoma, Ventura, Monterey, Big Sur and Catalina which for most people isn’t a problem as almost all major software is now 64-bit. Apple dropped support for 32-bit applications in macOS Catalina and the last macOS to support them was Mojave. MacOS Sonoma, Ventura, Monterey, Big Sur, Catalina and Apple Silicon M1/M2 Macs do not run 32-bit apps or games.
