  • Sep 11, 2019  MacOS 10.15 Catalina is coming, and it will be the first release to completely drop support for 32-bit apps. This means that apps that you rely on for your day to day workflow might suddenly not.
  • Oct 07, 2019  macOS 10.15 Catalina: The Ars Technica review iPad apps come to the Mac and old 32-bit apps go away in a wide-ranging update. Andrew Cunningham - Oct 7, 2019 5:00 pm UTC.

Oct 23, 2019  Apple has released macOS 10.15 Catalina around the world, adding new features including an improved Photos app, a new Music app and – most important to creatives – the Sidecar feature that lets you use an iPad and Pencil like a Wacom Cintiq. However, Catalina no longer supports 32-bit applications – it's 64-bit all the way. MacOS Catalina 10.15.5 introduces battery health management in the Energy Saver settings for notebooks, a new option to disable automatic prominence in Group FaceTime calls, and controls to fine-tune the built-in calibration of your Pro Display XDR. The update also improves the stability, reliability, and security of your Mac.

When Apple announced macOS 10.15 Catalina last month, it touted several new features, including the end of iTunes as we know it, better second screen support and window management, along with several other features, but there’s a dark side to Catalina that Apple’s not talking about nearly as much (and no, we’re not talking about Catalina’s new automatic dark mode).

Catalina is going to spell the end of the road for 32-bit Mac apps, meaning that many of your old apps could stop working completely when Apple’s next major operating system arrives this fall. Of course, you don’t have to upgrade, but if you want to enjoy all of Catalina’s yummy goodness when it arrives, you’ll want to be prepared so that you at least know what you might be sacrificing to move to this new island paradise.

The Death of 32-bit Apps

To be fair, this has been a long time coming, so it really shouldn’t be a surprise to anybody. As Apple notes, it began the transition to 64-bit apps over a decade ago, and when it announced macOS Mojave last year at WWDC 2018, it clearly told developers that it would be the last version of macOS that would be capable of running 32-bit apps.

In addition, Mojave hasn’t been shy about warning you if you attempt to open a 32-bit app, letting you know that it’s going to stop working soon, and recommending that you contact the developer to request a 64-bit version. Unfortunately, however, Apple decided not to be a nag about this, so the warning is only shown the first time you open a new 32-bit app.

This also isn’t the first time we’ve been down this road. Apple made the same move of killing off 32-bit apps on iOS, first warning users in iOS 10.3 in early 2017 before shutting them out when iOS 11 arrived later that year.

Ferreting Out Incompatible Apps

Since Apple only warns you about 32-bit apps once, you could probably be forgiven if you’ve forgotten that you still have some of these kicking around on your system, especially if you’ve been using a Mac for over a decade like we have. When you’re in the middle of a project, there’s definitely an understandable tendency to just click “OK” and figure you’ll deal with it later.

Unfortunately, “later” often never gets here, and many of us could be sitting on 32-bit apps that are vital to our workflow and waiting to self-destruct on us once we arrive on the shores of Catalina.

The good news is that there’s a fairly easy ways to identify if your apps are 32-bit or 64-bit, and you can do it using the tools that are already built into macOS — not only Mojave, but even in prior versions where the incompatibility warning doesn’t even appear.

Follow these steps to get a list of all of the apps installed on macOS and see if they’re 64-bit:

  1. Click the Apple logo () in the very top-left corner of your screen.
  2. Click About this Mac at the top of the drop-down menu that appears.
  3. From the About Window that appears, click the System Report… button. This will open a new app called “System Information.”
  4. Scroll down in the panel on the left under you see Applications, located under the Software heading.
  5. Wait for the list to populate. Depending on how many apps are on your Mac, this may take a few minutes.
  6. Once the list of apps has appeared in the main window, look for a column titled “64-Bit (Intel)”; note that you may have to scroll to the right or increase your window size in order to see it.
  7. Click on the “64-Bit (Intel)” column heading to sort by that column. All of your 64-bit apps (labelled “Yes”) and 32-bit apps (labelled “No”) will be grouped together.

You’ll notice that there are a lot of system apps in this list as well, including some by Apple itself. Most of these, however, ship with the operating system, and will therefore naturally be updated as part of macOS Catalina.

So What Can I Do About This?

If the only apps that have “No” beside them don’t really matter to you, there’s really nothing you need to worry about. You can delete those apps now or later, but they won’t prevent you from updating to Catalina, they’ll just stop working once you do.

If there are one or more important apps on the list, however, you’ll want to check with the app developer — either on their website or reaching out to them directly — to see if there’s either an update already, or if they’re at least working on one.

If the app in question came from the Mac App Store, it should be updated automatically, so if there’s an update available you should already have it. For apps installed from other sources, though, it’s a good idea to open them up and do a “Check for Updates” within those apps, assuming they have that capability (most apps put the option for this either on the app’s main menu or in their Help menu). If you don’t know how to get in touch with the developer, you can also often find contact information inside the app, either from the About option found on the app’s main menu, or within the app’s help screens.

Lastly, if there’s an app that you rely on that’s 32-bit and no longer in development, this is probably as good a time as any to start searching out 64-bit alternatives that are still being actively maintained by their developers.

With its enhancements and limitations, the new macOS 10.15 is inescapable. The official release is planned for September 2019, but Apple savvy users have tested Catalina long before — with the macOS 10.15 beta. If you’re not one of them, you might want to check the best assets of the new macOS here.

Catalina comes with extended workspace, no iTunes, and 64-bit app architecture. According to early user reports, the beta feels faster and more stable than the previous ones.

It’s not all rosy, though. By switching to 64-bit apps, macOS Catalina stops supporting the apps with 32-bit architecture. For you, this means no access to over 200 popular applications.

The bundle of incompatible apps have been discovered by iOS developer, Steve Moser, when he was testing the developer beta of Catalina. Once you upgrade, you can find the full list in Library/Apple/Library/Bundles.

We’ve collected the major Adobe, Apple, and Microsoft programs you’ll have issues with in macOS Catalina. No need to panic just yet — there are ways to fix this.

Which Mac apps will stop working

The problem of Catalina incompatibility is not only about third-party apps. Apple is not 100% prepared too. For people working with multimedia projects, it’s important to know which Adobe software won’t be working after the update. So take a deep breath, and see what’s going away.

Apple apps not working in Catalina

  • iWork’09, an old version of Apple’s office suite that includes Pages, Keynote, and Numbers. Apple released the newer bundle with 64-bit apps in 2013 — so an update will fix the problem here. Alternatively, you can get more advanced substitutes like Ulysses for writing and markdown.
  • Final Cut Studio and Logic Studio. You can upgrade to Final Cut Pro X and Logic Pro X instead.
  • Apple’s DVD Player (older versions released before macOS Mojave).
  • Aperture. The app won’t work in Catalina, even though it’s 64-bit. Apple recommends to switch to Photos or Adobe Lightroom. If you need a pro-level editor for a moderate price, you might want to try CameraBag Pro.

Microsoft apps not working in Catalina

  • The 2011 version of Microsoft Office (Word 2011, Excel 2011, PowerPoint 2011, Outlook 2011). To continue using the apps, get the 2016 version of Microsoft Office. Or, you can switch to Apple’s iWork, Ulysses, or other Mac alternatives.

Adobe apps not working in Catalina

Since Adobe moved to a subscription model called Creative Cloud, there has been lots of shared components introduced across Adobe products. For instance, if you buy a subscription, you may get a 64-bit application with a 32-bit installer. This won’t work in Catalina. Adobe says they are working on updating shared components for macOS 10.15. In the meantime, be aware of the incompatible apps:

  • Photoshop. There have been issues with the 2018 version of Photoshop in macOS Mojave, so you may expect the trouble in Catalina as well. If you want to use the app, Adobe recommends to get Photoshop CC 2019.
  • Premiere Pro. The app is 64-bit, but there have been reported issues related to camera and microphone access in macOS 10.15.
  • Illustrator. The CS5 version won’t be supported in Catalina, but you may switch to CS6.
  • InDesign. To this one, you have to say goodbye. At least, for now. The latest CS6 version hasn’t been updated to 64-bit architecture yet.
  • Acrobat Pro. The recent version of the app, as well as Acrobat DC and Acrobat Reader DC, have 32-bit components. So it’s a no, for now.

Most Adobe apps — even those with 64-bit architecture — are known for Dark Mode issues. So if you continue using the apps in Catalina, be careful with the darkness.

As a safe alternative, get CameraBag Pro or Capto. They work equally well for professional designers and amateurs. Both are available on Setapp, a subscription package that, by the way, offers many more photo editing tools — just ask for it.

How to check if an app is compatible with Catalina

We’ve talked a lot about outdated app architecture, so the first thing you’ll want to check when upgrading is whether your app is 32-bit. Here’s an easy way to do it on Mac:

  1. Click on the Apple logo in the upper left corner.
  2. Select About This Mac > System Report.
  3. Navigate to Applications under the Software tab.
  4. Find your app on the list and check whether it says “Yes” in the 64-bit column. In macOS Catalina, there will be no such column. So, you’ll have to click on the app and see a short description that says “Kind: 64-bit.”

We also recommend to pay attention to the “Obtained from” field. Ideally, it should say Apple, Mac App Store, or Identified Developer. Avoid using apps that are specified as “Obtained from Unknown,” while these are most likely to misbehave.

If you want to uninstall 32-bit applications before upgrading, CleanMyMac X will swipe everything away for you. Open the app and go to Uninstaller. Filter your apps by 32-bit and click Uninstall. Instead of checking System Report every time, you can find and remove every outdated application in a few seconds.

If your app doesn’t work in macOS 10.15

The problem with 64-bit architecture is that many developers choose not to optimize their 32-bit applications for Mac with the release of Catalina. If that’s the case and you can’t find an alternative for the missing app, you might need to downgrade back to Mojave. Luckily, there’s a way to fix most problems with apps not working in Catalina:

  • Check whether a developer has a 64-bit update for your app.
  • Look for an alternative app compatible with macOS 10.15. For instance, most of the Adobe apps for photo and video editing can be replaced with Capto or CameraBag Pro.
  • Roll back to Mojave and continue using 32-bit apps. You should note, though, that Apple may stop the support for Mojave by 2020, which means it will stop supporting 32-bit architecture sooner or later.
