What are 32-bit and 64-bit Apps? 64-bit apps can access more memory and potentially operate faster than 32-bit apps. That assumes, of course, your Mac has a 64-bit processor. Modern macOS.

The newest version of macOS will accelerate the phasing-out of 32-bit apps, Apple confirmed at WWDC on Monday, with Xcode 10 dropping support for the apps entirely.
At the WWDC State of the Union event, following the announcement of macOS Mojave (macOS 10.14) in the keynote earlier in the day, Apple vice president of software Sebastien Marineau revealed Mojave will be 'the last release to support 32-bit at all.'
'One of our key missions is always to push the Mac forward by extending its capabilities to take advantage of the latest technologies,' Marineau advised. 'As we push a platform forward, we sometimes have to deprecate legacy functionality to ensure that we're not holding it back.'
This means the QuickTime framework, Java 1.6 Apple framework and Carbon HLTB will be removed.
Apple also said at WWDC Monday that the new and redesigned Xcode 10 will drop support for 32-bit macOS apps. Development of 64-bit apps will remain unaffected by the change.
Apple debuted 64-bit support with Mac OS Leopard in 2007, and has slowly been phasing out 32-bit in recent years.
High Sierra had been announced as the last macOS release to support 32-bit apps 'without compromises,' and in April, macOS users began receiving alerts that 32-bit apps were not optimized for the current operating system. The move continues Apple's long phase-out of those apps.
MacOS users can use this test to find which 32-bit applications are on their desktop.
Mojave, which was introduced by Apple's Craig Federighi in the main keynote Monday in San Jose, includes such new features as Dark Mode, enhanced privacy and Desktop Stacks.

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:
Use virtualization to run your old apps
Here's a look at the best ways to run older software on your Mac.
Running older softwareApple 32 Bit Apps![]()
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.
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.

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!
