When a new version of macOS comes out, I usually upgrade my computer relatively soon. I like having access to the latest features, and significant macOS release upgrades are generally trouble-free. That hasn’t been the case with the newest version, Catalina. The trouble stems from the fact that Catalina doesn’t run 32-bit applications. Worst case scenario, you can simply not update to macOS Catalina, though Mojave—the last macOS operating system that supports 32-bit apps—should stop receiving support from Apple in 2020.
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.

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. Best mac apps fro drawing. We’ll start with the manual, more complicated method.
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:

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 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 be installed, including 64-bit versions where they’re available.

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.
What else is affected by dropping support for 32-bit?
Some media file formats won’t make the transition to 64-bit. Mac daily productivity app. 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 all your apps at once 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.

The announcement of macOS Catalina at the 2019 Apple Worldwide Developer Conference marks the end of 32-bit application support in the operating system. When the new OS debuts this fall, if you install macOS Catalina on your Mac you will find that any 32-bit apps you may have on your Mac will no longer work. The move away from 32-bit architecture to 64-bit began with iOS transitioning in September 2017 with the release of iOS 11 and the warning signs of 32-Bits demise in macOS have been prevalent in macOS Mojave for the last year. Launching any 32-bit apps in Mojave results in the OS warning you that the app needs updating.
Apple’s move to a 64-bit architecture is important as it frees developers of the limitations of the 32-bit architecture, from both a software and hardware standpoint. 64-bit apps are ready to use the technologies of today and will also be ready for those of tomorrow.
