Mac Os Catalina 32 Bit Games
For some publishers, updating countless classics simply isn’t worth the effort, leaving many 32-bit hits in the ground for good. While not one of the MacOS Catalina update’s advertised features, Monday’s update 10.15 removes support for 32-bit apps and games. If it’s not been updated to a 64-bit framework, it won’t launch on the updated OS.

- Mar 01, 2020 More importantly, if you’re looking to buy a new Mac, it will come with Catalina pre-installed. 32-bit games are gone for good 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.
- Dec 10, 2018 With the latest update to Mac OS, Catalina, apps that are 32-bit are no longer supported. This means that a vast majority of our older games will cease to work. Parallels Desktop, the virtualization software that allows you to run Windows on a Mac alongside macOS.
Steam will work fine on macOS Catalina, you just need to take some steps first
You'll have to ask Valve why they can't always update your 32-bit Steam client app to the 64-bit version that will run under macOS Catalina. But, AppleInsider is repeatedly being asked by users why their install is yelling at them that it needs an update.
The update from Valve is ready, and the Steam client will work just fine under macOS Catalina —you just may have to prepare the ground a little.
Catalina 32 Bit Application
Specifically, the problem is with the Steam client on your Mac. Even if you have shortcuts to your favorite games, they all launch through that Mac app, and it's possible that your copy of that is still a 32-bit app.If you're stuck with that 32-bit version, you have to manually get rid of it and then reinstall a new copy.
Oh, yes, it is. The Steam service is fine and so are at least most of your games. It's just the Steam client you have to fix.
Trash talk
One quick tip: do be certain to have your Steam account name and password to hand. You clicked that Remember Me button years ago, but this is going to appear to Steam as if you're setting up a new computer.
You'll have to be able to log in again, and you'll have to have access to email to get the verification codes that you'll be sent.
When you're sure you have the account details, start with this:
- Quit Steam
- Go to your Applications folder
- Drag Steam out to the Trash
If you have Hazel installed on your Mac, it will spot that you've removed an application and will offer to also delete all of that app's supporting files. As good as that is, as so much handier it is than going through the whole process of deleting them manually, don't let Hazel do it.
That's because Hazel will do too good a job and it'll remove everything. We want rid of a lot of Steam, but not the bit that includes your games.
If you have Hazel on your Mac, it will offer to delete Steam's supporting files. But you need the ones to do with your installed games, so click Keep All.
So next, you find all of Steam's supporting files from the Finder.
Hold Shift, Command and press G. In the Go to Folder dialog that appears, enter this: ~/Library/Application Support/ and click Go.
Hold down Command and Shift, then press the letter G to call up this Go To Folder dialog. You're going to get very familiar with it.
In the folder that opens, scroll to find the Steam folder, and delete everything in there except /steamapps. That directory is where your games live, and keeping that folder preserves the installs.
Next, repeat that Go to Folder with each of the following. In every one, look for Steam or Valve files.
- ~/Library/Caches/
- ~/Library/Logs/
- ~/Library/Preferences/
- ~/Library/Cookies/
- ~/Library/Saved Application State/
- ~/Library/LaunchAgents/
Do be careful to solely select Steam or Valve folders, but then drag them to the Trash and empty it.
Almost done
Now go to store.steampowered.com where you'll see an Install Steam button at the top right of the site.
Macos Catalina 32 Bit Games
Work through the steps it tells you. Then log back in to your Steam account, and you're done.There is, seriously, nothing you can do about games developers who haven't moved to 64-bit binaries. Barring a virtual machine or something else drastic, those games won't work under Catalina. But at least taking these steps now will save you having that awful moment when you've updated to Catalina, the Steam client won't load at all, and it appears as if you've lost all your Steam games.

With the arrival of macOS Catalina, Apple's transition towards 64-bit technology is complete. Starting with macOS Catalina, 32-bit apps no work on your computer. With that being said, there are some workarounds to consider if you happen to have older software that's essential for work or play. Think VM!
Do this first
Before doing anything else, you should check with the app developer to see if a 64-bit version of your software title is available. The transition to 64-bit technology was a lengthy one for Apple and the odds are high that your developer did make the switch.
Do you have 32-bit apps installed on your system?
Moving on, you can confirm whether you have 32-bit apps on your Mac by:
- Choose the Apple icon on the Mac toolbar.
- Click About This Mac.
- Select System Report.
Select Legacy Software in the sidebar. All legacy software is 32-bit.
Use virtualization to run your old apps
Here's a look at the best ways to run older software on your Mac.
Running older software
The issue with running old versions of software is that it can eventually 'break' and not function on a future version of the OS you are running it on. You can hope that the vendor of your application will keep on updating the software to run on future OS updates, but what if you have a very specific program that is no longer maintained? Or perhaps you have a software license for your current version of an application but upgrading to a more modern version introduces too great a cost?
Running a virtual machine
One possible solution to the 32-bit application dilemma is to run a version of the latest macOS that fully supports your app in a virtual machine. A virtual machine, or VM, is an emulated computer running on top of your current OS installation as a program. The VM takes resources from your actual computer and uses them to run itself in a contained environment as a separate system altogether. Think of it like the Matrix where the real world is your physical computer and the 'dream' world in the VM.
Benefits of a VM
Since you needn't buy new hardware, you can simply run an instance of the macOS version that will run your application without issue regardless of that app being 32 bit or 64 bit for as long as you keep your VM. If you upgrade the macOS on your physical Mac, the VM version is completely separate from that process so you'll still be able to keep the 'old' macOS on the VM and run the 'new' macOS for all of your other up-to-date programs. You'll be able to have your proverbial cake and eat it too.
Setting up a VM
There are a few options for VM software solutions for you to choose from. You can run Virtualbox, VMware, QEMU, and Parallels. All of the non-open source VM managers have free 'lighter' versions that will serve our purpose but you can get their full fledge versions that provide various features that are beyond the scope of this article.
We will be using Parallels Lite that is freely downloadable from the App Store. We chose Parallels Lite due to their ease of setup and ability to function on top of a macOS host passing system information that is needed for the guest macOS to properly install. Note that if one day you'd want to change your Mac's operating system to Windows or Linux then you'd might want to install one of the other mentioned VM managers since those can run on those host OSs albeit with a much more involved setup.
We will also be using macOS High Sierra as the installed OS. You can use these instructions for older versions as well. Credit to Howtogeek.com for the command line bits to make a disk image to install macOS High Sierra from their Virtualbox install instructions on Windows 10.
- Download Parallels Lite from the App Store.
Download (but do not install) macOS High Sierra.
We need to create the install image so we need to start Terminal.
- In Terminal in your home directory type or copy and paste line by line the following:
- hdiutil create -o HighSierra.cdr -size 7316m -layout SPUD -fs HFS+J
- hdiutil attach HighSierra.cdr.dmg -noverify -nobrowse -mountpoint /Volumes/install_build
- asr restore -source /Applications/Install macOS High Sierra.app/Contents/SharedSupport/BaseSystem.dmg -target /Volumes/install_build -noprompt -noverify -erase
- hdiutil detach /Volumes/OS X Base System
- hdiutil convert HighSierra.cdr.dmg -format UDTO -o HighSierra.iso
- mv HighSierra.iso.cdr HighSierra.iso
- Start Parallels Lite.
- Select Linux only.
- Click Continue.
- Select Install Windows or another OS from a DVD or image file.
Click Continue.
- Select Image File.
- Click Select a file.
- Navigate to your home directory and select the HighSierra.iso file we created in terminal.
- Click Open.
- Click Continue.
- Select macOS as the operating system type.
Click OK.
- Navigate to the folder to house the VM.
- Click Select.
Name your VM and click Create.
- You can optionally set up any VM options you desire such as (note that these can be changed later too):
- Startup and sharing settings in the Options tab.
- Choose CPU, memory and graphic options in the Hardware tab.
- Still under the Hardware Tab select the CD/DVD sub-option.
- Click the dropdown arrow for Source.
- Select Chose an Image File.
- Navigate to your home folder and select the HighSierra.iso file we created in terminal.
- Select Open.
- Select Continue.
- You can now Start the VM.
- Install macOS like you would normally do on any real system
Once you have a completed install, you'll want to install the Parallels Tools program in your VM macOS. This will allow you to be able to seamlessly use your mouse between your real desktop and your VM desktop as well as resize your VM screen on the fly with proper display attributes.
- Click the highlighted yellow exclamation point over your VM window.
- Click Continue.
On your VM, double-click the Parallels Tools installer that opens.
- Complete the installation and reboot your VM.
Final comments
You now have a full-fledged macOS installation that you can keep for your older 32-bit applications once macOS decides to give them the boot. You'll be able to make snapshots of the VM to have different save states. You'll be able to run all native macOS applications you normally do. The drawback will be the speed of execution and disk speed but if you have a powerful Mac, you may not notice too much of a difference depending on the application. Does this solution work for you? Tell us what you'd rather see happen for 32-bit applications on macOS in the comments!
