Last year, we were so obsessed with Apple deprecating OpenGL (spoiler: no real consequences have been seen one year later), we missed the real issue looming on the horizon: the removal of 32-bit support.

With the latest version of macOS, Catalina, games not Updated to 64-bit no longer work at all. And with Catalina’s surprise release, on October 7, this means you won’t be able to play several games you own if you decide to upgrade.

Some developers, such as Aspyr and Feral Interactive, have been proactive about which of their back-catalog games won’t be updated to 64-bit. But there are potentially hundreds of 32-bit Mac games that will never be updated.

To help you navigate these uncertain times, we decided to track all the Mac games we know won’t be updated:

And by the way, if you’re looking to buy a new Mac, it will come with Catalina pre-installed.

64-bit games for Mac: Confirmed!

To be fair with developers, we are also tracking the back-catalog games that have been updated to 64-bit (new games are all 64-bit):

The vast majority of new games are 64-bit, therefore no need to focus on those!

Steam on Catalina known issues

Steam is an essential part of gaming on a Mac. Chances are most of your games are Steam. This is why the current state of Steam on macOS Catalina is a shame.

For some reason, the Steam client itself has an update for Catalina, but it won’t update automatically. You’ll have to manually download it and install it. This page has all the information you need.

Last but not least, Steam “sometimes ” adds warnings to games that are not supported on Catalina. That would be great but there is one problem:

That information is inaccurate and should not be trusted.

You’ve been warned.

How do I check if an app is 32-bit or 64-bit?

As explained by Apple, finding out if a game supports 64-bit is easy:

• From the Apple menu, choose About This Mac
• Click the System Report button
• Scroll down to Software in the sidebar
• Select Applications

When selecting an individual application, you will see a field titled 64-bit (Intel). “Yes” indicates 64-bit; “No” indicates 32-bit:

You can also use a handy tool called Go64. It’s free, it’s easier to use and it’s coming from St. Clair Software, a veteran Mac developer.

Once you’re done, you can share a screenshot such as this one with us here and we’ll update the list accordingly!

This is only the beginning

Keep in mind we are only covering the games we are certain about.  There will likely be hundreds of indie developers who will not have the resources to update their older games. And the same goes for big publishers.

Even if they have the budget, many will choose not to update their older games that don’t sell well anymore. Sad but that’s how things will play out…

This is why we to help each other out. If you know about a game that we are certain it will not be updated to 64-bit, let us know!

What if you really need a 32-bit app?

If one of your favorite games is part of the list above and you want to keep playing it for many more years, you can always hold off and not upgrade your Mac to macOS Catalina.

With time, Macs that are not on macOS Catalina will miss on important new features and updates but it’s still a solution in the middle term.

When is macOS Catalina arriving?

Catalina is now available. It was released on October 7, 2019.
