Jun 05, 2018  Apple macOS Mojave will be the last version of the desktop operating system to support 32-bit applications, the company has confirmed at WWDC. Jun 12, 2018  In news that won’t surprise attentive TidBITS readers, Apple has announced that the upcoming macOS 10.14 Mojave will be the last to support 32-bit apps. If you rely on older 32-bit apps, you probably have at least 15 months before it becomes a problem in macOS 10.15. MacOS 10.14 Mojave, the version of the Mac operating system before the new macOS Catalina, is the last version that supports 32-bit software.With Catalina, only 64-bit software will be supported.

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. In macOS Mojave 10.14, this alert appears once every 30 days when launching the app, as macOS 10.15 will not support 32-bit applications. When Mojave is installed, it will convert solid-state drives (SSDs), hard disk drives (HDDs), and Fusion Drives, from HFS Plus to APFS. On Fusion Drives using APFS, files will be moved to the SSD based on the. When Mojave was released, it was announced to be the last macOS with 32-bit support, encouraging developers to update their software. Moving to 64-bit architecture in Catalina is definitely a good thing. While 32-bit processors and operating systems are long outdated, it makes much sense to take the apps to the new level as well.

The newest version of macOS will accelerate the phasing-out of 32-bit apps, Apple confirmed at WWDC on Monday, with Xcode 10 dropping support for the apps entirely.

At the WWDC State of the Union event, following the announcement of macOS Mojave (macOS 10.14) in the keynote earlier in the day, Apple vice president of software Sebastien Marineau revealed Mojave will be 'the last release to support 32-bit at all.'

'One of our key missions is always to push the Mac forward by extending its capabilities to take advantage of the latest technologies,' Marineau advised. 'As we push a platform forward, we sometimes have to deprecate legacy functionality to ensure that we're not holding it back.'

This means the QuickTime framework, Java 1.6 Apple framework and Carbon HLTB will be removed.

Apple also said at WWDC Monday that the new and redesigned Xcode 10 will drop support for 32-bit macOS apps. Development of 64-bit apps will remain unaffected by the change.

Apple debuted 64-bit support with Mac OS Leopard in 2007, and has slowly been phasing out 32-bit in recent years.

High Sierra had been announced as the last macOS release to support 32-bit apps 'without compromises,' and in April, macOS users began receiving alerts that 32-bit apps were not optimized for the current operating system. The move continues Apple's long phase-out of those apps.

MacOS users can use this test to find which 32-bit applications are on their desktop.

Mojave, which was introduced by Apple's Craig Federighi in the main keynote Monday in San Jose, includes such new features as Dark Mode, enhanced privacy and Desktop Stacks.
