macOS Ventura, Monterey, Big Sur, Catalina and M1 Macs do not run 32-bit apps or games. Apple dropped support for 32-bit applications in macOS Catalina and the last macOS to support them was Mojave.

You can only install 64-bit apps on Ventura, Monterey, Big Sur and Catalina which for most people isn’t a problem as almost all major software is now 64-bit.

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.

If you try to run a 32 bit-app in Ventura, Monterey, Big Sur, Catalina or an M1 Mac, you’ll get the following “App is not optimized for your Mac and needs to be updated” error message:

However, the problem for some Mac users is there are still some older applications and games that are still 32-bit only.

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.

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.

How To Play 32-Bit Games on a Mac

The only way to play 32 bit games or run 32 bit apps on macOS Ventura, Monterey, Big Sur, Catalina or M1 Macs is to install a virtual environment.

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).

On M1 Macs you can’t install an older version of macOS but you can install an M1 ARM chip compatible version of Windows instead.

This enables you to open applications in 32-bit mode on a Mac.

There are various virtual environments you can use to play 32 bit games or apps but not all of them work on macOS Ventura, Monterey, Big Sur Catalina or M1/M2 Macs because some of them (such as Wine) are 32-bit applications themselves and don’t work on the latest versions of macOS.

We recommend the best way to install 32-bit apps on a Mac nowadays is by using Parallels.

Parallels is the only way to run Windows on a Mac that is officially endorsed by Microsoft.

You can download a free trial version of Parallels to try this for yourself.

Parallels allows you to run Windows and older 32-bit compatible versions of macOS (such as Mojave, Sierra and High Sierra) simultaneously so whenever you need to use a 32 bit app, you can just switch to your Windows or older macOS installation in Parallels.

Not only this, but Parallels works on M1 & M2 Macs and by allowing you to install Windows 10 on a Mac, it allows you to run 32 bit Windows games and apps on an M1 or M2 Mac.

Parallels is now so well integrated with macOS that you can launch 32-bit apps from the Dock as if they were installed on your Mac natively.

However, note that this only works for 32 bit Windows ARM compatible apps and games.

Due to the complexities of running 32-bit apps in Windows ARM on an M1/M2 Mac, it also may not work with every game or application.

Be aware also that if you want to use a 32-bit plugin such as for a music application, the entire music production suite must be installed in the virtual environment.

You can’t install the 32-bit plugin in Parallels and expect it to work with your music software installed in the latest versions of macOS due to technological limitations.

Parallels has provided full instructions on how to run 32 bit apps on an Intel Mac, using an installation of High Sierra as an example but the same method would apply if you were installing Mojave or Windows instead.

32 Bit Games & Apps on M1 & M2 Macs

Running 32 bit games and apps in Ventura, Monterey, Catalina and Big Sur on M1 & M2 Macs is more complicated than on Intel Macs.

Older versions of macOS in a virtual environment only work with Intel chips. So only Intel Macs can install older versions of macOS such as Mojave or High Sierra.

And Boot Camp does not work with M1 or M2 Macs so you can’t install older versions of macOS using Boot Camp on an M1/M2 Mac.

So there’s no way to install an older version of macOS on an M1 or M2 Mac to run 32 bit games and apps.

However, M1 and M2 chip Macs can run a 32 bit version of Windows 10 and Windows 11 using Parallels so if the 32-bit game or application you want to run is available on Windows you can run with Windows version on an M1 Mac.

It’s important to be aware though that M1 and M2 chip Macs can only run the ARM-chip compatible version of Windows 10 and 11.

This means that the 32-bit game or app you want to use must be compatible with Windows 10 or Windows 11 on ARM.

A few Adobe apps such as Lightroom are Windows 10 on ARM and Windows 11 on ARM compatible but most Adobe software isn’t for example.

The good news is the latest version of Windows 10 ARM and Windows 11 ARM can also run other Intel only software as it can perform what’s known as x64 emulation which means almost all 64-bit software will run on it.

The bad news is that it won’t work with 32-bit software and it’s currently only available in the Preview version of Windows 10 and 11 ARM.

The bottom line is, if the game or app is 32-bit Windows 10 ARM or Windows 11 ARM compatible you can use it on an M1 or M2 Mac.

If it isn’t, there’s no way to play or use it on an Apple Silicon M1 or M2 Mac.

You can find full instructions how to install Windows 10 on M1 Macs here and Windows 11 on a Mac here.

    The virtual machine won’t work for utilities. One of the very most valuable utilities I ever encountered is Print Selection by Chimp Studios. It was 32 bit, never upgraded to 64-bit, Chimp Studios folded, and the app was removed from the App Store. However, it’s absolutely indispensable to me, and having it in a Parallels virtual machine is of no use whatsoever when wanting to print a selection from a Web page.
    I therefore went to Time Machine, selected the executable of PrintSelection from the Applications Folder on a date prior to the upgrade and Restored it. Time Machine moved it to the Applications folder of Monterey, and it WORKS. It’s not full functioned. It used to have the capability of editing what was selected before printing, and trying that now locks up the app. However, that was used rarely, and I can live without it. So far, I DO have the ability to select text or images from almost any Mac application and print just the selection at the top of a page.
    IF someone would get the source code and upgrade this app so that it runs in Monterey and Ventura, I’d pay ten times the old price of $4.99 for it, but for now there is NO other app in the world, that I can discover, that provides this capability.
