Summer is over and autumn is upon us. This means the weather is changing, kids are back at school, and Apple has released a new version of its Macintosh operating system.
How to uninstall apps on macOS Catalina. When you install macOS 10.15 on your computer, the system informs you that some of the installed apps are not optimized to run on your Mac. These 32-bit apps are not compatible with macOS Catalina. Once macOS 10.15 is installed, the icons of incompatible programs are crossed out in the Applications folder. MacOS Catalina is here, and with the update comes the transition from 32-bit apps to 64-bit apps. Overall, this is a good thing because it means that apps will run faster and access more memory.

And if you need to run a 32-bit application for daily use a Virtual Machine is not recommended (even though it can be done), in that case it is probably best to either use a ‘two Mac strategy’ with one running macOS 10.14 Mojave and one running macOS 10.15 Catalina, or – if you insist on using one Mac only – to run macOS 10.14 Mojave. Note that the 64-bit (Intel) column header does not show up in the report under macOS Catalina — ostensibly because 32-bit apps are no longer valid applications and won’t show up in this report at all — so you should run this check before upgrading to macOS Catalina. Now just because an app is 32-bit right now, doesn’t mean it will not.
The latest release is version 10.15, also known as Catalina. You can upgrade if your Mac is 2012 or newer, however, as with any upgrade there are always challenges when it comes to hardware and software compatibility.
One major change in Catalina is that it only supports 64-bit apps and does allow 32-bit apps to run. This means some third party applications will not work after the upgrade.
To check the apps on your Mac, go to the Apple menu and select About This Mac. Click on the System Report, then scroll down and select Applications. Old unit 6 agendamrs. colvilles math class. The rightmost column of this report shows 64-bit (Intel) compatibility.
One more thing to remember is that there are other reasons for an app to stop working. A 64-bit app might still run on the new operating system but that doesn’t mean it will work the way it should. The best way to check software’s compatibility is to refer to the manufacturer’s website to see if it will work under Catalina.
At last year’s WWDC, Apple announced that macOS Mojave will be the last version of macOS to run 32-bit apps. With public beta of the next major version of macOS — macOS Catalina — now here, it’s no surprise then that Catalina has dropped support for 32-bit apps. While most popular apps will remain unaffected by the change, it’s possible that some of your apps will no longer run under macOS Catalina.
If any of your apps has recently given a warning that it is “not optimised for your Mac and needs to be updated” when launched, it will not work when you upgrade to macOS Catalina. If you’ve not come across this warning but are curious to see what apps on your Mac are still 32-bit, it’s pretty simple to do that.
How to find 32-bit apps on your Mac
Here’s how to check what apps on your Mac are 32-bit if you are running macOS Mojave or earlier:
- Click on the Apple icon in the top-left corner of your screen.
- Click on About this Mac.
- Click on System Report…
- In the left pane, select Applications sub-head under Software.
- Click on the 64-Bit (Intel) column header — usually the rightmost column — to sort the list of apps by this value.
- All apps with No are 32-bit apps.
Note that the 64-bit (Intel) column header does not show up in the report under macOS Catalina — ostensibly because 32-bit apps are no longer valid applications and won’t show up in this report at all — so you should run this check before upgrading to macOS Catalina.
Now just because an app is 32-bit right now, doesn’t mean it will not be 64-bit in the future. In fact, if the Obtained from value for the app in question is Mac App Store, Apple, or Identified Developer, chances are that this app will make the transition to 64-bit at some point in the future.
If, however, the value if Unknown, the app faces an uncertain future.
Why is Apple dropping support for 32-bit apps in macOS Catalina?
Here’s what Apple has to say on the subject:
All modern Macs include powerful 64-bit processors, and macOS runs advanced 64-bit apps, which can access dramatically more memory and enable faster system performance. The technologies that define today’s Mac experience—such as Metal graphics acceleration—work only with 64-bit apps. To ensure that the apps you purchase are as advanced as the Mac you run them on, all future Mac software will eventually be required to be 64-bit.
What popular apps will stop working in macOS Catalina?
Older versions of some popular apps by Adobe and Microsoft are still 32-bit and will stop working. Both Adobe and Microsoft have released modern, 64-bit versions of their apps, and if you are a Creative Cloud/ Office 365 subscriber, you won’t face any problems as you’ll be able to download the latest versions of all apps, and, in fact, are likely already running 64-bit versions of all apps.
If, however, you had purchased and are still hanging on to your Illustrator CS5 or InDesign CS5, or the Microsoft Office 2011 suite, you will need to figure out an alternative.
Android File Transfer app will also stop working unless an update is released.
My favourite app doesn’t run in macOS Catalina — what are my options?
Here are a few things you can do if your favourite app won’t run anymore in macOS Catalina:
Macos Catalina 32 Bit Support
Make sure you are running the latest version of the app. If you aren’t on Catalina yet, launch the app and go to the About screen (click on the name of the app in the top-left corner, and click on About AppName) to check the version of the app. Visit the developer’s website to see if a new version of the app is available.
Most non-App store apps will also let you check for updates from within the app either from the application menu. You can do this by clicking on the name of the app in the top-left corner and seeing if there’s a Check for Updates option. Alternatively, check within the app’s Preferences for something similar.
App Store apps are automatically updated by default, unless you’ve disabled automatic updates.
Contact the developer to see if there are plans to release an updated version of the app.
If the app is critical for your workflow, you can obviously keep running the version of macOS you are currently running and not upgrade to macOS Catalina until you’ve figured out an alternative.
