Apr 15, 2020 Apps won't work in macOS Catalina One of the most controversial changes included with macOS Catalina is the fact that it no longer supports 32-bit apps. This means any apps that don't have a.

When macOS Mojave was announced, Apple warned that it would be the last version of macOS that would support older 32-bit apps. Apple has been phasing out 32-bit apps for the last 10 years and is now ready to take the final step, even if Mac users may not be ready to lose access to older apps. Iphone to mac transfer.

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.

32-bit vs. 64-bit

32-bit apps date back to a time when there were 32-bit processors and 32-bit operating systems, but are now outdated. Apple has long since transitioned to 64-bit processors and macOS has been 64-bit since the launch of Snow Leopard in 2009.

Compared to 32-bit apps, 64-bit apps can take advantage of more memory and offer faster system performance. Apple technologies like Metal only work with 64-bit apps, and for Apple to ensure that Mac apps include all of the latest advancements and optimizations, support for 32-bit needs to end. In the simplest terms, 32-bit apps are inefficient.

32-bit apps can run on a 64-bit system as they've been doing for years, but Apple wants to get rid of outdated apps to make sure everything that runs on the Mac is properly optimized and isn't an unnecessary drain on system resources.

Previous Warnings

Apple started warning Mac users about plans to end support for 32-bit apps back with macOS High Sierra. In High Sierra, users started getting warnings about a 32-bit app's future incompatibility with macOS.


A similar message was available in macOS Mojave, and if you opened up a 32-bit app while running Mojave, you saw an alert letting you know a specific app wouldn't work with future versions of macOS unless it was updated.

Alerts re-appeared every 30 days when launching an app, with Apple aiming to make sure customers would not be caught unaware when a 32-bit app stopped working in the future, so you should already know if one of your frequently used apps hasn't been upgraded to 64-bit.

Upon updating to ‌macOS Catalina‌, you'll be shown a list of 32-bit apps that no longer work on your system.

How to Check if an App is 32-Bit or 64-Bit in macOS Mojave

Macos

To determine whether an app is 64-bit or 32-bit and to see if there are 32-bit apps installed on your machine before upgrading to ‌macOS Catalina‌, follow these steps:

  1. Click the Apple symbol () in the menu bar on your Mac's desktop.
  2. Click on About This Mac.
  3. Choose 'System Report' at the bottom of the window.
  4. Scroll down to the Software list on the sidebar.
  5. Select Legacy Software.'

Anything in the list of Legacy Software applications is a 32-bit app and will not work when upgrading to ‌macOS Catalina‌.

If Legacy Software isn't an option in the sidebar, select the Applications option and then check the list of apps at the right. The column that's labeled 64-bit will show a 'No' listing for apps that are 32-bit.

How to Prepare to Update to ‌macOS Catalina‌

The first step is to make sure there aren't already available updates for apps that you have on your system, which you can generally do by updating through the Mac App Store for ‌Mac App Store‌ apps.

Apps outside of the ‌Mac App Store‌ use other update methods that can vary by app, but for many, you can click on the app's name in the menu bar and choose the 'Check for Updates' option. Some other apps have more hidden update methods, so if you do have a 32-bit app, make sure to Google how to update it to be sure there's not already new software available.

After ensuring you've updated everything you're able to update, you can contact developers and ask them to update their apps, but if that doesn't pan out, the only other solution is to start the search for an alternative app if you're committed to upgrading to ‌macOS Catalina‌ or have already done so.

32-Bit App Warnings When Installing Catalina

When upgrading to ‌macOS Catalina‌, the installer will show a list of recently used apps that are 32-bit so you know what to expect before installing.


After viewing this list, you can choose to either cancel or continue with the installation.

‌macOS Catalina‌ also shows a stop symbol over the icon of 32-bit apps in the Finder, so you know that the app isn't going to open.

Aperture

With the release of ‌macOS Catalina‌, Aperture is going to stop working. Apple warned Aperture users in April 2019 that the software won't run in future versions of macOS, starting with ‌macOS Catalina‌.

If you're an Aperture user, you'll have to transition to alternate photo editing and management software, such as Adobe's Lightroom. Aperture is not 32-bit, but Apple is phasing it out all the same.

Affected Media Formats

Certain media files that use older formats and codecs are also not compatible with macOS after macOS Mojave due to the 64-bit transition, and you will need to convert some iMovie and Final Cut Pro X libraries. Incompatible media files were created using codecs that rely on QuickTime 7, and while macOS Mojave has QuickTime 7 frameworks, future versions of macOS will not.

Apple has a full list of media formats that are going to be affected by the transition available in a support document.

Continuing to Use 32-Bit Apps

In macOS Mojave and earlier versions of macOS like High Sierra, you can continue to use your 32-bit apps. If you have a 32-bit app that you absolutely depend on, you're going to want to think twice before upgrading to ‌macOS Catalina‌.

Apple is ready to give you a change — the all-new macOS Catalina, available as a free download — so let’s get you all set.

There are two different options on how to upgrade. You can install Catalina over your current macOS, keeping all its data untouched. Or, you can get a fresh start with a clean install. The main benefit of clean installation is that you get rid of the system junk and leftovers which might hamper your Mac’s performance.

Get Setapp to get ready for Catalina

A complete toolkit of utilities that prepare your Mac for macOS Catalina install. Upgrade your Mac in minutes without losing any data.

One way or another, getting Catalina on your Mac is definitely worth a try. Look at the bells and whistles it brings along:

  • A renewed iTunes experience — with dedicated apps for Music, Podcasts and Apple TV.
  • Simplified porting of iOS apps to macOS.
  • Sidecar for using your iPad as an additional screen.
  • Major updates of your favorite native apps, including Photos, Reminders, and Find My.

And that’s only a small part of your new macOS experience. If you need more reasons, find a complete review of the new Catalina features here.

Prepare your Mac for the clean install

If you’ve seen the new Catalina, you must be excited to get your hands on the installer — we get it. But don’t dive right into the upgrade. Your Mac has to be ready. First thing, check device compatibility. The rules are not much different from the Mojave compatible Macs, except for a few older Mac Pro models that Catalina will no longer support. Here’s the full list:

  • MacBook Air (2012 or newer)
  • MacBook (2015 or newer)
  • MacBook Pro (2012 or newer)
  • Mac Pro (2013 or newer)
  • Mac mini (2012 or newer)
  • iMac (2012 or newer)
  • iMac Pro (all models)

Found your Mac on the list? Congrats, you’re on the Catalina team. Just a few more things and you’re ready to install:

How To Install Catalina On Macbook

  1. Get a USB drive with minimum 16GB of free space if you plan to install Catalina on a startup disk.
  2. Backup your data and clean away all the clutter.
  3. Note that it will take your Mac an hour or two to run the upgrade.

Choose your way to clean install Catalina

As we’ve said before, the healthiest method of clean installing the new macOS is by putting it on your startup drive. It’s your perfect choice if your Mac has a single non-partitioned drive where all the files are stored. Simply backup an entire drive and go ahead with the installation.

Another choice would be to test Catalina on a non-startup drive. If you have a spare drive or your startup drive is divided into volumes, this might be a good option to explore. Especially if you don’t want any files to go away.

Let’s dive into the details of clean installation.

Clean install macOS 10.15 on a startup disk drive

Again, this is the recommended option that will leave you with a high-performing Mac. It involves lots of cleaning and securing your files, though. You can take care of all the data stored on your old OS manually, or by using a few easy utilities. Let’s save your time and see how to do it real quick:

Remove junk from your Mac with CMM X

Download a powerful macOS cleaner to get ready for the Catalina upgrade. All the junk, leftovers and old caches will be gone in a moment.

Step 1. Get rid of the junk

Every ancient app leftover that is hiding somewhere in the depths of your Mac may potentially hinder its performance. That’s not what you want. CleanMyMac X can handle the junk before an upgrade. In one smart scan, the app will spot and remove everything — from outdated caches to file duplicates.

One more important detail, Apple will stop supporting 32-bit applications in the new macOS 10.15. So make sure you get rid of them, too. This will help you see the functionality that Catalina will be missing, and find the right alternatives in advance. In CleanMyMac X, navigate to the Uninstaller tab, filter apps by 32-bit, and click Uninstall. As easy as that. Find out what to do when scratch disks are full in photoshop.

Clean Install Macos Catalina

CleanMyMac X is a nice utility to keep on your new macOS, too. In fact, it’s the quickest way to refresh an entire system and remove potential threats before they start affecting your performance. The app is available on Setapp — and so is the backup utility for your Mac we’ll talk about in a moment.

Step 2. Backup your drive

You want the redundant files to go. But you also want the needed files to stay. That’s easy with Get Backup Pro, one of the best backup apps for Mac. Unlike Apple’s native Time Machine, Get Backup Pro has the functionality of creating bootable clones — which gives you absolute peace of mind. In case there’s a tech problem with your Catalina installation, the drive can be recovered at any time.

We encourage you not to ignore the backup process. It will help you roll back at any time with minimum loss. Plus, it’s an easy way to move your files to the new OS in batch.

Step 3. Create a bootable Catalina installer

Before you clean install Catalina, we have to warn you there might be no going back. First, because macOS 10.15 is truly great. Second, because Apple removes an old macOS installer from the App Store once the new version is out. So if you want to have an exit plan, you’ll have to download Mojave installer in advance.

Here’s how you create Catalina installer:

  1. Access the App Store and get the new macOS Catalina.
  2. Wait for the download process to finish and click File > Quit as soon as the installer launches. Your installer will be stored in the Applications folder.
  3. Connect your USB stick and go to Disk Utilities.
  4. In the Erase tab, select Mac OS Extended (Journaled) as your format.
  5. Name your USB stick and then click Erase > Done > close Disk Utility.
  6. 6. Access Terminal and type the following command (make sure you replace [XXX] with your drive name):sudo /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/[XXX] --applicationpath /Applications/Install macOS Catalina.app
  7. Hit Return and type in your admin password.
  8. When the process is finished, click Done and close Terminal.
  9. Congrats, you’re a Catalina user — now officially.

Step 4. Get Catalina on your startup drive

The final part. Your data is securely backed up, so you can go ahead and erase your startup disk drive:

  1. Access System Preferences > Startup Disk and choose your Catalina installer.
  2. Restart your Mac and hold Command-R.
  3. Connect your bootable USB.
  4. In the macOS Utilities window, click Reinstall a new copy of macOS.
  5. Click Continue and agree to the terms and conditions.
  6. Select your startup drive and click Install.

Once the new macOS gets on your Mac, it will be born anew. So yes, you will have to set it up — just like a new Mac. If you’ve used Setapp on the old macOS, you can quickly get your apps back by downloading the installer on setapp.com.

Clean install macOS 10.15 on a non-startup disk drive

If you don’t have a free, non-partitioned drive, you can install Catalina on a non-startup drive. Here are three easy steps:

Step 1. Erase your non-startup drive

If you install Catalina on a new drive, this is not for you. Otherwise, you’ll have to wipe everything away from the drive before using it. Navigate to Disk Utility, select your non-startup drive, and click Erase. If there’s any data you want to keep, use ChronoSync Express to sync it with another drive.

Step 2. Download the Catalina installer

Access your Mac App Store > Updates and grab the installer. Once the installer will launch automatically, quit — you don’t want to install it from there.

Step 3. Install Catalina to your non-startup drive

You’ll find the downloaded installer in your Applications folder and launch it. Select a drive — you’ll have to change it from “startup” to your target one. Follow the instructions and finish your installation.

Once your system is upgraded, set up your new Mac and make sure you try all the perks. And before you get frustrated that your favorite 32-bit app is missing, get Setapp — it surely has a decent alternative.
