Use System Report To Find a List Of 32-Bit Apps On Mac
System Report is a super cool utility on your Mac that lets you find out lots of information about the hardware and software elements on your machine. Although its main purpose is not to help you find apps on your Mac, it does help you find all the 32-bit apps sitting on your machine.
Here’show to get to the list of all the 32-bit apps installed on your Mac:
- Click on the Apple logo at the top-left corner of your screen and select About This Mac. On the following screen, click on the button that says System Report beneath your Mac details.
- By default, you’ll be in the Hardware tab in the report utility. Expand the apps list by clicking on Software followed by Applications in the left sidebar.
- You’ll see a list of all the apps installed on your Mac. Scroll right and take a look at the 64-Bit (Intel) column. If it says No for an app, it means the app you’re looking at is a 32-bit app.
Thisway you can easily find out whether an app is 32-bit or 64-bit.
Use Activity Monitor To Find 32-bit Apps On Mac
Another way to find 32-bit apps on your Mac is to use the Activity Monitor tool. The tool does let you find out if an app is 32-bit but the app must be running while you try to find this information. You won’t find any information if the app isn’t running on your Mac.
- Launch the app in question on your Mac but don’t do anything with it. Open Activity Monitor from the Launchpad.
- Right-click on any of the column names (CPU Time, Threads, etc) and select Kind. It’ll add a new column to the right of existing columns.
- The newly added Kind column will tell you whether the app currently running on your Mac is 32-bit or 64-bit.
Bothof the methods described above should help you easily find all the32-bit apps available on your Mac.
What To Do With The 32-Bit Apps?
If you’ve found that some of your apps still use 32-bit architecture, you may want to upgrade them to the 64-bit versions as soon as possible. If you don’t do it, these apps won’t run on macOS 10.15 and later.
Mostdevelopers are aware of this change that Apple has made to macOS andthey may have already released the 64-bit versions of their apps.There are a few ways to check if your existing apps have 64-bitversions available for your Mac.
Update The Apps From The Mac App Store
If your 32-bit apps were downloaded from the Mac App Store, it’s likely the developer has pushed a 64-bit upgrade to the store. In that case, all you need to do is update the app as you would normally and it’ll then be compatible with the newer versions of macOS.
- To upgrade your apps, launch the Mac App Store on your Mac.
- Click on the Updates option at the top to access the update panel.
- If an update is available for your apps, you’ll find an Update button next to them.
- Click on the button and the apps will be upgraded to their newer versions.
Get The Latest Version From The Official Website
Itmay be that the 32-bit app you use on your Mac came from a website onthe Internet. In that case, you may want to check out the officialwebsite for the app to see if a 64-bit update is available.
Simplyhead over to the app website and look for a newer version of the app.If it’s available, download and install it on your machine. Yourexisting app will be updated to the latest version.
Update The App From Within The App
Manyof the apps allow you to get updates from within the app menus. Thisis true for apps like iTunes, Chrome, AppCleaner, among others.
Inmost apps, you can get new updates by clicking on the app name at thetop and selecting Check for updates or a similar option. Ifyou find an update is available, select it to install it on yourmachine.
Conclusion
If you haven’t already done so, go ahead and get all of your 32-bit apps upgraded to the 64-bit versions if you still want these apps to run in the latest macOS versions. Not doing so will make your apps dysfunctional.
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
Find All 32 Bit Apps On Mac Computer
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:
- Click the Apple symbol () in the menu bar on your Mac's desktop.
- Click on About This Mac.
- Choose 'System Report' at the bottom of the window.
- Scroll down to the Software list on the sidebar.
- 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.
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
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.
