Apple has announced that its upcoming macOS Mojave release for Macs will officially be the last to support 32-bit apps.
The Final Version to Support 32-Bit Apps. During the State of the Union presentation, Apple confirmed that Mojave will be the last version of macOS to support 32-bit apps. When a user tries to open a 32-bit app, Mojave currently displays a one-time warning that the app will not work in future versions of macOS.
The company made the announcement after unveiling macOS Mojave at WWDC earlier this week, sharing the news on 32-bit apps with developers following the keynote event.
Apple first introduced support for 64-bit apps way back in 2007 with the release of OS X Leopard, and last year’s macOS High Sierra release was the last to support 32-bit apps “without compromise”, according to Apple.
Jul 16, 2018 Almost all previous 3rd-party apps work on Mojave. Some 32-bit ones will launch but quit (WhatRoute and TextEditPlus). When I do run a 32-bit app, I get the warning that it won't be supported in future OS's. Little Snitch runs but takes up a lot of system resources, so I had to uninstall it. Aside from that, the Mojave beta works reasonably well. Download the latest version of Krita for FREE on your device. Available on Windows, Linux, OSX, and Android tablets. Oct 11, 2019 How to Run 32-Bit Apps in macOS Catalina. Apple's latest version of macOS, Catalina, officially ditches 32-bit app support, but you can still run the software you need by following these steps.
Back in April, Apple started pushing a notification to users on macOS 10.13.4 when opening 32-bit apps, warning that the app would need to be updated and optimized by the developer:
Apple didn’t elaborate on exactly what the compromises might be with 32-bit apps running on Mojave, but it confirmed that it would indeed remove support entirely starting with next year’s macOS release.
As Apple officially removes 32-bit support next year, it will also remove related 32-bit only frameworks including the QuickTime framework, Java 1.6 Apple framework, and Carbon HLTB.
Apple gave us our first look at macOS Mojave to kick off WWDC on Monday, with features including a new dark mode, Home app, and a redesigned App Store. It also gave us a sneak peek at its plans to make it easier for devs to bring iOS apps to Mac, noting that it used the in-testing tech to bring the Home app, Stocks, and Apple News to Mojave.

Apple began transitioning to 64-bit hardware and software technology for Mac over a decade ago, and all modern Macs now include powerful 64-bit processors that can run advanced 64-bit apps. These apps can access dramatically more memory, enable faster system performance, and take advantage of technologies that define today's Mac experience, such as Metal graphics acceleration.
Apple has been working with developers to transition their apps, and in 2018 Apple informed them that macOS Mojave would be the last version of macOS to run 32-bit apps.
Apple's transition to 64-bit technology is now complete. Starting with macOS Catalina, 32-bit apps are no longer compatible with macOS. If you have a 32-bit app, please check with the app developer for a 64-bit version.
Opening 32-bit apps
When you attempt to open a 32-bit app, you will see an alert that the app needs to be updated to work with this version of macOS, or that the app is not optimized for your Mac and needs to be updated.

How to find 32-bit apps on your Mac
System Information can find 32-bit apps that are installed on your Mac:
- Choose Apple menu > About This Mac, then click the System Report button.
- Select Legacy Software in the sidebar. All legacy software is 32-bit.
- If you don't see Legacy Software in the sidebar, select Applications in the sidebar, then check the list of apps on the right. The column labeled ”64-Bit (Intel)” shows ”No” for apps that are 32-bit.
When upgrading to macOS Catalina, the installer shows a list of recently used apps that are 32-bit. You can review this list before choosing whether to cancel or continue the installation:
macOS Catalina also shows a prohibitory symbol over the icon of each 32-bit app in the Finder, letting you know that the app will not open.
