Options to keep 32-bit Mac games playable on a Mac computer: Consider not upgrading to macOS 10.15 or above. By staying on macOS 10.14 Mojave or older you will ensure that your 32-bit apps are still playable on your Mac computer. After upgrading to macOS 10.15 Catalina, consider installing macOS 10.14 Mojave on a separate APFS volume on your. Oct 11, 2019 The 32-bit apps you find on your machine are typically of two kinds: older Mac apps that have been abandoned by their developers (or that developers are slow to update) and apps.
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!
- MacOS 10.14 Mojave, the version of the Mac operating system before the new macOS Catalina, is the last version that supports 32-bit software.With Catalina, only 64-bit software will be supported.

With that being said, there are some workarounds to consider if you happen to have older software that's essential for work or play.
- Click 64-bit apps, to sort the apps. Here, you'll see the 32-bit apps that are not going to work in macOS 10.15. Follow my tips above to find your way to a solution.
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will keep on updating the software to run on future OS updates, but what if you have a very specific program that is no longer maintained?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?

A fresh start is not a challenge in the Mac universe. Quite the opposite, getting a macOS upgrade every September marks a surge of new features and functionality enhancements—all coming right your Mac’s way.
Apple introduced the perks of macOS 10.15 at the 2019 WWDC, and lots of features have been tested and discussed since then. A dual monitor available with the Sidecar feature, the Photos app update, and a brand-new iTunes made the show this year. Lots of features migrate from iOS, the others appear for the first time. If you’re wondering why Catalina is worth an upgrade, check the full list of killing features here.
Traditionally, there are two stages at which you can try macOS Catalina before it’s officially released. Starting June, there’s a developer beta available, and about a month later—a public one.

A few things before you switch to Catalina
Your to-do list for the upcoming upgrade:
![Windows Windows](/uploads/1/2/6/2/126293930/999615767.jpg)
- Ensure your device is compatible. As usual, there’s a limited number of Apple devices that support macOS 10.15. It’s not too different from what we had last year, but take a look anyway. Sometimes the reason why you can’t upgrade lies on the surface:
- MacBook Air (2012 or newer)
- MacBook (2015 or newer)
- MacBook Pro (2012 or newer)
- Mac Pro (2013 or newer)
- Mac mini (2012 or newer)
- iMac (2012 or newer)
- iMac Pro (all models)
- Say goodbye to 32-bit apps. Mojave was the first macOS to stop admitting 32-bit apps to the App Store and the last to support them. In Catalina, you’ll have to limit your Mac to 64-bit applications only. Once you install macOS 10.15, you’ll be warned about 32-bit apps not working on your Mac any longer. CleanMyMac X will help you quickly filter applications by 32-bit and get rid of them:
- Backup valuable data. When we’re too excited, we tend to rush things. Remember though, that a new macOS means a new start—wiping away the past. To keep your data safe, create a backup before upgrading. You can use Apple’s in-built Time Machine or more advanced tools like Get Backup Pro if you want a bootable backup.
- Clean up your Mac. You need to free up some space for your new macOS. Even if you have enough, running a cleanup is a nice way to start a clutter-free life in Catalina. From redundant apps to caches and leftovers, you can remove any unnecessary items with CleanMyMac X.

How to install a developer beta of macOS Catalina
Downloading and installing macOS Catalina developer beta is an easy deal if you have a Developer account. Here’s how it works:
- Go to developer.apple.com and click Account in the top menu bar.
- Sign in with your account credentials.
- Select Downloads > Install Profile.
- Find and launch the installer in your Downloads folder.
- Open the PKG file and agree to the installation.
- If required, verify the account by entering your system password or with Touch ID.
- Find the update in System Preferences.
- Click Upgrade Now to install the beta.
Test macOS 10.15 on a partition
If you’re not ready to give up Mojave just yet, you can install Catalina on a partition. Basically, it allows to split your disk into two parts, so that your computer can run two operating systems at the same time.
To install Catalina on a partition, go to Applications > Utilities > Disk Utility. Your disk will be the first on the list under “Internal.” Select the disc and navigate to Partition tab. Click the plus button to split your disk, name your partition, and customize the size if needed. Click Apply and you’re ready to drive. Or, rather, double drive.
Clean install macOS Catalina on Mac
If you’re determined to give your Mac a new life, run a clean install of Catalina. In contrast to a regular install which puts macOS on top of your startup disk content, a clean installation cleans everything up. Risky as it sounds, a clean install enables a healthier life for your macOS. Just make sure you don’t lose anything in the shuffle:
- Create a safe bootable backup of your disk with Get Backup Pro.
- Connect a clean and reformatted external hard drive or a USB stick.
- On the disk, create a bootable installer.
- Erase your startup disk with Disk Utility and boot from the new one.
- When installing macOS Catalina, choose your new disk as the install location.
If you decide to go with a regular install, note that all the clutter from your disk will be transferred to the new operating system. So we recommend to make use of CleanMyMac X smart scanning before you upgrade.
Download and install Catalina Public Beta
A developer beta opens up an early access to all the features. The problem is it’s not free. To get your hands on Catalina with a developer account, you have to pay a yearly fee of $99. Therefore, you might want to wait for Apple to make it public.
Arriving in July, a public beta of Catalina is available at beta.apple.com/sp/betaprogram/. Once there, it takes a couple of steps to upgrade:
- Log in with your Apple ID.
- Navigate to Enroll your Mac section and click on “Download the macOS Public Beta Access Utility.”
- Once downloaded, run the installer.
- Open System Preferences. You’ll find the public beta update under Software Update (macOS Catalina beta).
- Click Upgrade now to download the installer. Go through the installation if you want to put beta on your current Mac, or quit to create a bootable USB install drive first.
The pitfalls of Catalina beta
Macos 10.15 Run 32 Bit Apps
To put it shortly, it’s buggy. Just like any other macOS beta, Catalina can slow down your Mac, freeze, or hinder the work of some apps. It’s ok.
There are a couple of things you can fix, though:
- If you have issues with Sidecar: Ensure your iPad runs on the new iPadOS beta. The feature won’t work on iPadOS 12.
- If an app doesn’t open: Hope you remember, 32-bit apps are dead in Catalina. So if some of your software doesn’t work on the new macOS because of 32-bit architecture, look for alternatives.
- If iCloud doesn’t work properly: Try to close and reopen a document, or download files manually if iCloud Drive fails to load them.
Once you notice imperfections, help to fix them. Beta users can report bugs through Apple’s in-built Feedback Assistant app.
Hopefully, Catalina is worth an upgrade for you. If not, you can downgrade anytime to continue your journey with Mojave. If an operating system doesn’t solve some of your tasks, let Setapp cover the needs. It’s a curated collection of Mac apps that helps you with screenshots, PDF editing, file management, and tons of other jobs—150 at the very least.
