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:

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.
Are you worried some of your favorites games will no longer be supported? Let us know in the comments section.
Bioshock Infinite is on my List of Games to play.
I will have to finish it, before Catalina arrives.
You can still run your games by loading PARAELLS on APPLE I did this and I can run all my old games thank you NJJ.
Except there is no 3D HW-acceleration on Mac guests (but on Windows and Linux guests there is, which is better to run games in).
Glad they updated Borderlands 2.Still love that game.
I love the Pre-Sequel almost as much BL2, and there is no updates for it 🙁
And what about bootcamp with PC version ? I guess all pc versions of these games will be updated to 64.
BootCamp (i.e. Windows games) aren’t affected.
Way easier than Boot Camp would be just dual-booting Mojave and Catalina.
Other than Windows, macOS allows installation on external media so you’re not limited to your internal drive capacity.
What about Crusader Kings 2?
EVE Online is in 64-bit beta currently so some good news there
Personally even with a mid-2017 iMac I am still going to give Catalina a miss.
Odd how GOG Galaxy is a YES but Steam shows up as NO on my system. Also, none of my installed Steam games even show up on the list, nor do many of the games I have on my system.
The Steam client has been mostly 64-bit for a while, but there is a small launcher app that apparently doesn’t get updated automatically. You can fix this by trashing (or renaming) the old Steam app and downloading a fresh new one. (You won’t lose any Steam settings or game installs.)
Halo Combat Evolved.
Unreal Tournament 2004.
🙁
Hey Ric this is not the end of the world in my opinion.Sure some of those games listed are favorites and if so do not update for awhile.I read somewhere that from here on out Aspyr is going 64 bit only on there future offerings .All my 64 bit games run pretty good and metal really flies.I would rather quality over quantity anyway and this is just one mans opinion.Just to let you know the updated games listed work great.ps..i hope tf2 gets updated.
The easiest solution is to just keep a Mojave installation around for legacy games!
Unlike Boot Camp, that doesn’t have to be on your internal drive, can be any external disk or USB thumbdrive, so you could even use it on several Macs if you need to.
So unless platforms like Steam decide to drop support for Mojave one day, we can keep on playing all the 32bit games we own.
I agree that this is a great option. But note that the version of macOS that came with your Mac is the earliest version compatible with that Mac. So the next time you upgrade your hardware you will be out of luck.
That is true indeed. In that case, it’s probably best to keep some older Mac around.
Counter Strike Global Offensive is working on Catalina.
TF2 not yet 🙁
Can anyone confirm if the Baldur’s Gate (Enhanced Edition) I and II games are 64-bit compatible? They are listed as most recent update version 2.5.x at the MAS. But the MAS tells you nothing about 32 or 64 bit compatibility in games.
Yes they are.
Guild Wars 2 does not work with Catalina currently. The main app is 64 bit so Catalina says it is ok … and then part of it calls some 32 bit code (running their store, crucial to the game dochaknow). Resulting in a crash. The developers have yet to say what the status of it is.
Starcraft and Warcraft 3 are already 64bit.
How is Stellaris on the ‘updated’ and ‘not updated’ list?
You’re correct. The game started as 32-bit only a few weeks ago but we since discovered it has a 64-bit update coming. I have now kept it in the 64-bit confirmed list.
Thanks for the heads up.
Will Left4 dead 1 and 2 be supported on catalina?
In regards to the games listed as “Not yet updated”, has the developer/publisher been either been contacted or otherwise released information stating their intention to update the game; or is “Not yet updated” meant to be synonymous with “future unconfirmed”?
I, personally, am specifically concerned with the update status of Valve Games, especially the Portal and Half-life games. Any information would be appreciated.
Also, I’m having trouble with the text fields on this site. (Safari 13.0.1). Specifically, the text fields forcing capitalization regardless of caps lock status and unavoidable via copy and paste as well. Thanks
Two really old, but great games: Apeiron X and Quinn will not work; both i386, both discontinued.
Hearthstone is 64-bit ready.
Football manager is not on the list but doesnt run
Which one are you referring to?
Age of Mythology for Mac??
I have not played Maelstrom for years. I loved that game. I’m glad to see it’s alive and on the Updated list. But, Ambrosia the company has been gone for years. Where can I find the 64-bit version of this classic game?
I don’t see XCOM: Enemy Unknown. Feral’s website specifically stated that this game is 32-bit only and won’t be updated. Also, I think Space Hulk and Space Hulk: Ascension are also 32-bit only?
the cave will also not be continued 🙁 loved that game..
Note that you can also click the Legacy Software option which should list only 32-bit apps and plugins.
I believe that Deus Ex Human Revolution is 32 bit. Also, the original Bioshock, although Bioshock Remastered is 64 bit.
Team Fortress 2 🙁
Perhaps (and probably) this has already been mentioned, but you can designate a partition on your hard drive to Catalina. In that way you can keep your partition with 32-bit games as they are and boot up Catalina when needed. If you do as mentioned above, please download Catalina from the App Store, do not do so via System Update however (and uncheck ‘ Automated system updates’). Via Utilities >> Disk Utility >> select hard drive >> Partition. Hold the Control key when starting up and select your desired partition to boot. In this way, there’s no problem.
Does anybody know why Steam lists some of the games flagged as “Updated” here as “Not Compatible” with Catalina? Examples include Baldur’s Gate EE 2 and Pillars of Eternity: Deadfire.
I keep hearing that Steam’s “not compatible with Catalina” messages are often inaccurate. It would have been a great feature but I’m afraid we can’t trust Steam.
On the other hand, this list is updated with first hand tests on our behalf but also feedback from readers. The status for some of these games will change overtime so it will be a challenge to always be 100% up to date…
Steam still has some games listed with a notice that they’re not compatible with Catalina (Cities: Skylines, Dawn of Man). These games are listed here as Updated. Who do I trust?
Steam is showing lots of wrong warnings. I have no idea why but I wouldn’t trust them: https://www.reddit.com/r/macgaming/comments/dihobe/psa_there_appear_to_be_a_lot_of_false_negatives/
That seems to be the case. The compatibility issue is supposed to be for 32-bit games and Dawn of Man distinctly says it requires a 64-bit minimum.
Found this list too late …:( how bad. What about The Witcher 2? 🙁 🙁 🙁
updated to catalina to see if i would like it, and i wish i didn’t, there are still a lot of 32 bit games and apps i would like to use
For the person asking about Maelstrom: the game was open-sourced awhile ago, making it possible to migrate to 64-bit at anyone’s leisure. I have a fork myself.
Do you know if Slime Rancher will be updated?
What about witcher 2, will it be updated?
Does anyone know if Left 4 dead 1 and 2 will be supported soon does not yet updated mean there will be an update in teh future?
try to contact the developer
I just bought Shelter 2. Add it to the list of not compatible.
Thanks for taking the time to do the research.
I missed all this until it was too late. I WAS playing Half Life 2, mac updated to Catalina and now 95% of my games inc Half Life are unsupported. Gutted. Insurgency is on your list of updated but it wont run on my mac as its apparently 32 bit.
It’s not true that ARK: Survival Evolved is updated. At least not on Steam.
SpaceChem
Many games on steam are marked as 32bit or not working on catalina, but in reality they just work fine. It is fault of developers to fix game description and settings on steam so games can be seen as working games for users. I have plenty of games on steam for mac and only about few (I can name 4 from the top of my head) that are really 32bit and not working, the rest I have only problem with security issues on Catalina – steam overlay needs security grant for every game to accept keystrokes from any app. In many cases I just get error message, but that message is not error for game being 32 bit. To solve this user have to open local files (right click on game and then properties, find local files button/tab) and run game.app file manually. This will fire up game and hopefully you will get popups for keystrokes and to grant access to disk to game so it can load up and use disk for loading/saving games.
On another note, many games on steam for mac are actually built with Unity Engine, which means developers has little to do to update game to 64bit – in most cases just recompile to 64-bit and that will automatically ship 64bit libraries together with game. So if you know for some game that uses Unity and developer hasn’t updated the game yet, please write them and notify them about that. Also please, if you see game on steam marked as not working and it is actually working, notify developers to fix this. This will also help them sell more as many users will not buy a game if they see a warning message saying that game won’t run on Catalina.
