Macos Catalina 32 Bit Support
- Oct 09, 2019 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.
- Oct 15, 2019 One of the biggest issues is the removal of support for 32-bit based applications - historically a huge part of the macOS software portfolio. Many of these apps are still in active development.
When using macOS 10.15 Catalina (or higher), if you're using Harmony Hub or a hub-based remote such as; Harmony Elite, Companion/Home Control, Smart Control, Ultimate Home, or Ultimate, you can continue to use. The Harmony mobile app on iOS or Android; The current MyHarmony app on a Windows; The current MyHarmony app on a macOS 10.14 or lower.
macOS Catalina (or macOS version 10.15) is coming in October 2019, bringing with it a slew of really nice improvements and new features.
However, unlike earlier macOS releases – you need to prepare for macOS Catalina, or you could run into trouble right after the upgrade!
macOS Catalina Requirements
Before we start, make sure you have one of these systems – macOS Catalina will only run on these Mac computers.
- iMac Pro : All models
- iMac : Late 2012 or newer
- Mac Pro : Late 2013 or newer
- Mac mini : Late 2012 or newer
- MacBook Pro : Mid 2012 or newer
- MacBook : Early 2015 or newer
- MacBook Air : Mid 2012 or newer
macOS Catalina – Don’t Upgrade Until You Do This First!
Unlike earlier versions of macOS, Catalina drops support for 32-bit apps. Therefore, you must check if you are still using any 32-bit apps before you upgrade.
Here is a step-by-step guide on how to check for 32-bit apps in macOS :
- Click on the Apple icon on the top left of the task bar.
- Select About This Mac from the pull-down list.
- In the Overview screen, click on the System Report… button.
- When System Report loads, select Software > Applications from the column on the left.
- It will now take a minute or two to scan all of your apps.
- Once it loads, you can scroll through all of your apps to look for any that have their 64-Bit (Intel) status marked No.
- However, an EASIER method is to locate the 64-Bit (Intel) column, and click on it to list all those marked No at the top.As you can see, quite a number of applications, including those used to setup the actual apps, are still 32-bit apps.
- Now, you need to uninstall all those 32-bit apps and replace them with 64-bit versions. Otherwise, they will all fail to work once you upgrade to Catalina!
Why Do You Need To Run This Check Again?
You need to find out what 32-bit apps you are still running, because they will NOT work after you install macOS Catalina.
You will need to upgrade these 32-bit apps with newer 64-bit versions, BEFORE you upgrade to macOS Catalina.
Can’t I Upgrade My Apps After I Upgrade To macOS Catalina?
It is possible to remove your 32-bit apps and install their 64-bit versions after upgrading to macOS Catalina.
However, you may have trouble removing all of the older components, if the old 32-bit app used an installer.
So we highly recommend that you uninstall all 32-bit apps, and install their 64-bit versions… BEFORE you upgrade to macOS Catalina.

Apple last month started warning users of 32-bit apps that future versions of macOS would not run ‘without compromise.’
It was a vague warning, but suggests that Apple does have a plan to allow 32-bit apps to continue to run even after macOS has nominally switched to a 64-bit-only environment …
One possibility is that it will, for a time, offer a virtual machine running an older version of macOS silently in the background.
Does Macos Catalina Support 32-bit Apps
But even if Apple does eventually cease support for 32-bit apps altogether, as seems likely, a virtual machine could provide a DIY solution, as MacWorldsuggests. (Though the piece does mix up version numbers rather!)
It’s not widely known, but VMWare Fusion and Parallels Desktop can run virtual versions of macOS, too. There are a few limitations. First off, you can only emulation [sic] macOS on hardware running macOS. Second, there are some specific versions of macOS that are allowed for virtualization […]
You’re free to virtualize Mac OS X 10.7 Mavericks, Mac OS X 10.8 Yosemite, Mac OS X 10.9 El Capitan, Mac OS X 10.10 Sierra, and macOS 10.11 High Sierra. (Presumably Apple will continue allowing future versions of macOS to run in virtualization on Mac hardware.)
So if you have old software that you’re afraid isn’t going to work in a future macOS version, fear not: You should be able to install macOS in VMWare Fusion or Parallels Desktop and keep using that app. You can even set the virtualization software to open in a full-screen space on your Mac, so you can swipe on a trackpad from High Sierra to Mavericks and back.
If you’re not sure whether you’re still using any 32-bit apps, here’s how you can find out.
