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!

Apple is making it clear that 32-bit apps on the Mac are going away and the future will be 64-bit only. So how to you tell if your Mac has a 32-bit or 64-bit processor? Read on to learn how. Visit our list of games compatible with macOS Catalina. Check back often as we’ll be adding games to this list regularly. Find the game you’d like to play, open the Game Manager and click on the Mac Games tab (or the Purchase History tab if you have already purchased the game). Search for a game from the list of compatible titles.

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:

1. Choose the Apple icon on the Mac toolbar.
2. Click About This Mac.
3. Select System Report.

4. 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will keep on updating the software to run on future OS updates, but what if you have a very specific program that is no longer maintained?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.

1. Download Parallels Lite from the App Store.

2. Download (but do not install) macOS High Sierra.

3. We need to create the install image so we need to start Terminal. Free games for mac os.

4. In Terminal in your home directory type or copy and paste line by line the following:
   1. hdiutil create -o HighSierra.cdr -size 7316m -layout SPUD -fs HFS+J
   2. hdiutil attach HighSierra.cdr.dmg -noverify -nobrowse -mountpoint /Volumes/install_build
   3. asr restore -source /Applications/Install macOS High Sierra.app/Contents/SharedSupport/BaseSystem.dmg -target /Volumes/install_build -noprompt -noverify -erase
   4. hdiutil detach /Volumes/OS X Base System
   5. hdiutil convert HighSierra.cdr.dmg -format UDTO -o HighSierra.iso
   6. mv HighSierra.iso.cdr HighSierra.iso
5. Start Parallels Lite.
6. Select Linux only.
7. Click Continue.
8. Select Install Windows or another OS from a DVD or image file.

9. Click Continue.

10. Select Image File.
11. Click Select a file.
12. Navigate to your home directory and select the HighSierra.iso file we created in terminal.
13. Click Open.
14. Click Continue.
15. Select macOS as the operating system type.

16. Click OK.

17. Navigate to the folder to house the VM.
18. Click Select.

19. Name your VM and click Create.

20. You can optionally set up any VM options you desire such as (note that these can be changed later too):
    1. Startup and sharing settings in the Options tab.
    2. Choose CPU, memory and graphic options in the Hardware tab.
    3. Still under the Hardware Tab select the CD/DVD sub-option.
    4. Click the dropdown arrow for Source.
    5. Select Chose an Image File.
    6. Navigate to your home folder and select the HighSierra.iso file we created in terminal.
    7. Select Open.
    8. Select Continue.
21. You can now Start the VM.
22. Install macOS like you would normally do on any real system

New 32 Bit Computers

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.

Help a space explorer achieve his wildest dreams. Take on assignments and make new discoveries.

1. Click the highlighted yellow exclamation point over your VM window.
2. Click Continue.

3. On your VM, double-click the Parallels Tools installer that opens.

4. 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?

Another day, another iPhone 12 Pro concept. How much would you pay?

If reports are accurate we might be waiting a little while longer than normal for iPhone 12 Pro. But would you care if it looked like this?

When macOS Mojave was announced, Apple warned that it would be the last version of macOS that would support older 32-bit apps. Apple has been phasing out 32-bit apps for the last 10 years and is now ready to take the final step, even if Mac users may not be ready to lose access to older apps.

With the release of macOS Catalina, 32-bit app support is no longer available, which means many of your older apps will no longer work if they haven't been updated to 64-bit.

32-bit vs. 64-bit

32-bit apps date back to a time when there were 32-bit processors and 32-bit operating systems, but are now outdated. Apple has long since transitioned to 64-bit processors and macOS has been 64-bit since the launch of Snow Leopard in 2009.

Compared to 32-bit apps, 64-bit apps can take advantage of more memory and offer faster system performance. Apple technologies like Metal only work with 64-bit apps, and for Apple to ensure that Mac apps include all of the latest advancements and optimizations, support for 32-bit needs to end. In the simplest terms, 32-bit apps are inefficient.

32-bit apps can run on a 64-bit system as they've been doing for years, but Apple wants to get rid of outdated apps to make sure everything that runs on the Mac is properly optimized and isn't an unnecessary drain on system resources.

Previous Warnings

Apple started warning Mac users about plans to end support for 32-bit apps back with macOS High Sierra. In High Sierra, users started getting warnings about a 32-bit app's future incompatibility with macOS.

A similar message was available in macOS Mojave, and if you opened up a 32-bit app while running Mojave, you saw an alert letting you know a specific app wouldn't work with future versions of macOS unless it was updated.

Alerts re-appeared every 30 days when launching an app, with Apple aiming to make sure customers would not be caught unaware when a 32-bit app stopped working in the future, so you should already know if one of your frequently used apps hasn't been upgraded to 64-bit.

Upon updating to ‌macOS Catalina‌, you'll be shown a list of 32-bit apps that no longer work on your system.

How to Check if an App is 32-Bit or 64-Bit in macOS Mojave

To determine whether an app is 64-bit or 32-bit and to see if there are 32-bit apps installed on your machine before upgrading to ‌macOS Catalina‌, follow these steps:

1. Click the Apple symbol () in the menu bar on your Mac's desktop.
2. Click on About This Mac.
3. Choose 'System Report' at the bottom of the window.
4. Scroll down to the Software list on the sidebar.
5. Select Legacy Software.'

Anything in the list of Legacy Software applications is a 32-bit app and will not work when upgrading to ‌macOS Catalina‌.

If Legacy Software isn't an option in the sidebar, select the Applications option and then check the list of apps at the right. The column that's labeled 64-bit will show a 'No' listing for apps that are 32-bit.

How to Prepare to Update to ‌macOS Catalina‌

The first step is to make sure there aren't already available updates for apps that you have on your system, which you can generally do by updating through the Mac App Store for ‌Mac App Store‌ apps.

Apps outside of the ‌Mac App Store‌ use other update methods that can vary by app, but for many, you can click on the app's name in the menu bar and choose the 'Check for Updates' option. Some other apps have more hidden update methods, so if you do have a 32-bit app, make sure to Google how to update it to be sure there's not already new software available.

After ensuring you've updated everything you're able to update, you can contact developers and ask them to update their apps, but if that doesn't pan out, the only other solution is to start the search for an alternative app if you're committed to upgrading to ‌macOS Catalina‌ or have already done so.

32-Bit App Warnings When Installing Catalina

When upgrading to ‌macOS Catalina‌, the installer will show a list of recently used apps that are 32-bit so you know what to expect before installing.

But now the pictures won't show up when I try to take them. I tried to install CRE. First time I missed the bit about 1.3.34 so it didn't work, would just open a black screen then close out. I just save and close out, then bring it back up and it fixes it for a bit. It runs pretty smooth for a while, then starts to get laggy.

After viewing this list, you can choose to either cancel or continue with the installation.

‌macOS Catalina‌ also shows a stop symbol over the icon of 32-bit apps in the Finder, so you know that the app isn't going to open.

Aperture

With the release of ‌macOS Catalina‌, Aperture is going to stop working. Apple warned Aperture users in April 2019 that the software won't run in future versions of macOS, starting with ‌macOS Catalina‌.

If you're an Aperture user, you'll have to transition to alternate photo editing and management software, such as Adobe's Lightroom. Aperture is not 32-bit, but Apple is phasing it out all the same.

Affected Media Formats

Certain media files that use older formats and codecs are also not compatible with macOS after macOS Mojave due to the 64-bit transition, and you will need to convert some iMovie and Final Cut Pro X libraries. Incompatible media files were created using codecs that rely on QuickTime 7, and while macOS Mojave has QuickTime 7 frameworks, future versions of macOS will not.

Apple has a full list of media formats that are going to be affected by the transition available in a support document.

Continuing to Use 32-Bit Apps

64-bit Games

In macOS Mojave and earlier versions of macOS like High Sierra, you can continue to use your 32-bit apps. If you have a 32-bit app that you absolutely depend on, you're going to want to think twice before upgrading to ‌macOS Catalina‌.
