When Apple launched macOS Mojave in 2018, it announced that it would be the last version of macOS that would support 32-bit applications. From Catalina onwards, you will no longer be able to run 2-bit apps and will have to upgrade to 64-bit versions or find alternatives.

1. Is My Mac 32 Or 64 Bit

Beginning June 1, 2018, all new app updates submitted to the Mac App Store had to support 64-bit. Apple is expected to phase out support for 32-bit apps in macOS 10.15, which will almost certainly be previewed at the 2019 Worldwide Developer Conference in June. (It’ll kick off on Monday, June 3.). Once it’s finished, scroll sideways to right until you see the header 64-bit (Intel). Apps will have a Yes/No designation to determine whether they are 32-bit Mac apps or not. “Yes” means they’re. I can't find the apps on my Mac. When you install Office 2016 for Mac, the app icons aren't automatically added to the dock. To add to the dock, drag the app icon from the Launchpad or the Applications folder.

What are 32-bit apps?

These applications date back to the days when computers ran on 32-bit processors and had 32-bit operating systems. While often described in terms of speed and power, the real difference between 32-bit and 64-bit whether it’s applications operating systems, or CPUs, is the amount of memory they can address. 32-bit apps can only address 4GB of RAM, so that is the maximum amount of RAM they can use.

Why has Apple stopped supporting 32-bit apps

Apple has been using 64-bit processors in Macs for well over a decade and macOS has been 64-bit since Snow Leopard, so it was only a matter of time before the Mac became 64-bit only. That time is now. Apple believes that the apps most people use most of the time are 64-bit and those that haven’t made the leap have good 64-bit alternatives.

It has also provided plenty of warning. When you open a 32-bit app in Mojave or High Sierra for the first time, you are warned that it is 32-bit and that you should update it. That warning then appears again every month or so.

By dropping support for 32-bit apps, Apple can fully optimize macOS Catalina for 64-bit apps and focus its resources on supporting those.

Is my app 32-bit or 64-bit?

When you upgrade to Catalina, you’ll be shown a list of any 32-bit apps you have installed and that will no longer work. If you want to check before then, you have two options: one very easy and the other a little more complicated. We’ll start with the manual, more complicated method.

1. Click on the Apple logo at the top of the screen.
2. Choose About this Mac.
3. Select System Report at the bottom of the window.
4. Click on Applications and scroll to the right until you see the column headed ’64-bit’.
5. Apps that have a yes in the column are 64-bit and will work, those with a ‘No’ are 32-bit and won’t work.

There is an easier way to check, and it’s the one I recommend because it will allow you to upgrade 32-bit apps to their 64-bit versions at the press of a button. It uses the Updater utility in CleanMyMac X — a cool program by MacPaw — and it’s so simple to use. Here’s how:

1. Install, and launch CleanMyMac X — it’s free to download
2. In the app, click on the Uninstaller tab

Now, press the “32-bit” tag in the sidebar on the left

You will see the list of your apps that will not be supported on Catalina. Some of them may already have the 64-bit versions available. So instead of updating each app separately and wasting time browsing, just put the cursor on the tab below called “Updater”

Check the box next to each of the apps and press Update. The most recent versions of all the apps displayed will by installed, including 64-bit versions where they’re available.

How can I keep running 32-bit apps on macOS Catalina?

If you have 32-bit apps that you depend on and absolutely can’t use another app, and there is no 64-bit version available, you have three options.

1. Don’t upgrade to Catalina. If you carry on using Mojave, or whatever version of macOS you’re using, you will be able to keep using 32-bit apps. However, it’s unlikely that the developer of those apps will continue to update them once Catalina is launched, as fewer and fewer people will use them. For example, shortly after Apple announced Catalina, games developer Aspyr announced that it would no longer sell 32-bit games. You will also be missing out on all of the benefits of Catalina.
2. Upgrade to Catalina on your main Mac but keep another Mac running an older version of macOS. This relies on you having more than one Mac, of course. But it does mean you can enjoy the new features in Catalina and still use your old 32-bit apps. However, the same thing applies as above: your 32-bit apps are unlikely to be supported and updated for long. That includes security and compatibility updates.
3. Run Mojave in a virtual machine, such as VMWare Fusion.

What else is affected by dropping support for 32-bit?

Some media file formats won’t make the transition to 64-bit. Most of these were created using formats or codecs that rely on QuickTime 7, according to Apple. The QuickTime 7 framework is included in Mojave and its predecessors, but won’t be there in Catalina, so formats created with it won’t work. Apple has a full list of affected formats here.

That means some Final Cut Pro and Motion projects won’t be compatible. However, if you open a project with a 32-bit format, you will see a warning and will be able to convert the library to a 64-bit compatible format at the click of a button. You will also be able to convert Final Cut libraries at any time from the File menu by choosing Check Media for Compatibility. And you can convert files in Compressor.
Dropping support for 32-bit apps in macOS Catalina is part of a long transition from 32-bit to 64-bit that started with hardware and then with the OS in Snow Leopard. Apple has been supporting both for many years, but has decided the time is now right to become a 64-bit only operating system. Fortunately, most apps have already migrated to 64-bit and you can update any apps you need to using CleanMyMac X’s Updater. For apps that don’t have a 64-bit version, you need to decide whether to find an alternative or not upgrade to Catalina.

OverDrive for Mac is available for macOS versions 10.6 (Snow Leopard) through 10.14 (Mojave). If you're running one of these macOS versions, you can use OverDrive for Mac to download, listen to, and transfer MP3 audiobooks from your library.

OverDrive for Mac and OverDrive MP3 audiobooks are not compatible with the newest macOS version, 10.15 (Catalina), which was released on October 7, 2019. This is because Apple requires all apps in macOS Catalina or newer to be 64-bit, and OverDrive for Mac (which is required for downloading MP3 audiobooks) is 32-bit. If you're running macOS Catalina or newer, these are your audiobook options:

• Listen to audiobooks in your web browser using your library's website. Once you borrow an audiobook from your library's website, choose the 'Listen now in browser' option.
• Listen to audiobooks in your web browser using Libby (for public libraries) or Sora (for schools).
• Install the OverDrive or Libby app (for libraries) or the Sora app (for schools) directly on a compatible portable device and listen to audiobooks through the app.
