The day is rapidly approaching where Apple will just disallow 32-bit apps from running on iOS, maybe as soon as iOS 11. AppleInsider shows you how to identify which apps installed on your iPhone are 32-bit — and points out some problems that Apple needs to rectify before that day comes.
Apple has included a new Settings pane in iOS 10.3 to easily check for installed 32-bit apps, and to see if there are updates available.

Feb 08, 2018 How to identify 32-bit apps on your Mac. To prepare for a future in which 32-bit software will no longer run without compromise, it may be a good idea to figure out which of the installed apps found on your computer are still 32-bit. Here’s how 1) Choose About This Mac.
Jun 05, 2018 This is the first of many warnings Apple plans to provide as it works to put an end to 32-bit apps on the Mac, as it did on iOS devices with the release of iOS 11. How to Identify 32-Bit Apps. Oct 09, 2019 32-bit apps can run on a 64-bit system as they've been doing for years, but Apple wants to get rid of outdated apps to make sure everything that runs on the Mac is properly optimized and isn't an.
To check, open Settings. Tap on General. Tap on About, and select Applications. This brings up a list of the installed apps that are 32-bit.
In our device, we've got four apps — two games and two educational titles — that are 32-bit with no updates. In our spot-checks, educational and entertainment titles are the heaviest-hit by the shift, as they have historically been.
It is unfortunate that some apps will be left behind in the shift, but every computer user has dealt with a change from on-high affecting software libraries before. The earliest releases of OS X included a Classic OS9 environment that wasn't perfect — which was killed seven years later in 2007 with the release of 10.5.
Be wary of older apps that haven't been updated in a while.
To facilitate the shift to Intel processors, Rosetta was included with 10.4.4 in 2006, and killed when 10.7 shipped five years later in 2011. These are just recent examples for Apple — Windows users have the same pain, just sometimes with less advanced notice.
This has all happened to us before — it happened with the 68K to PowerPC shift, with every big OS migration, and with the shift from PowerPC to Intel. As with any architecture shift, some users get left behind.
Apple is responsible for the safety and speed of iOS and the iPhone. It has told developers for three years, since a note in December 2014, that updates to software needed to include 64-bit support. Apple is clearly not responsible for ensuring that all iOS software works forever, on every combination of iOS and hardware.
Apple has been enforcing the requirements since June 2015. When iOS 9 rolled out, it warned that 32-bit apps could cause slowdowns, with iOS 10.3 now more forceful and straight-out says that 32-bit app support would be discontinued in a future iOS revision — which is probably iOS 11.
If you have an app that won't make it past the end of the 32-bit compatibility era, blame the developer — there's been ample warning. If the app is mission-critical, then don't upgrade your hardware's OS revision, and don't plan on moving the app to new hardware.
Apple can still make this less painful, if it chooses
What Apple will not do, is retain 32-bit compatibility forever. Older 32-bit software has been on life support since the A7 processor in the iPhone 5S in 2013.
However, there are a few things it can, and should, do to ease the transition.
At this time, there does not appear to be a way to check apps in iTunes to see if they are 32- or 64-bit — but that would be helpful. So, for now, the only way to know for sure is to check on your iOS 10.3 device.
The identification tool now in Settings in iOS 10.3 is a good start. However, Apple needs to be more forthcoming about this in the App Store, as well as giving users a clear identification of which apps are 32-bit in iTunes before the support is fully dropped.
For now, before you install new-to-you, be wary of older apps that haven't been updated in a while. This extends even to apps from larger vendors, like 'Civilization Revolution 2' in our screen captures.

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.
Check 32 Bit Apps On Mac
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
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:
- Click the Apple symbol () in the menu bar on your Mac's desktop.
- Click on About This Mac.
- Choose 'System Report' at the bottom of the window.
- Scroll down to the Software list on the sidebar.
- 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
Check 32 Bit Apps Mac
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.
