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. Meanwhile, some long-term macOS developers will have to scramble to update their old 32-bit apps before that 2019 version arrives, since Mojave is the last macOS version that will run 32-bit apps at all.

Another noteworthy mention regarding compatibility and macOS Mojave pertains to 32-bit apps, as macOS Mojave is apparently set to be the last version of Mac OS system software to support them. You can read here to learn how to find 32-bit apps on a Mac if you are not sure which apps may fall into that category.
At last year's Worlwide Developer's Conference (WWDC), Apple announced to Mac app developers that macOS High Sierra 'will be the last macOS release to support 32-bit apps without compromise.' Now, in the macOS High Sierra 10.13.4 beta, Apple is notifying users of the impending change, too.
In the beta release notes, Apple says:
To prepare for a future release of macOS in which 32-bit software will no longer run without compromise, starting in macOS High Sierra 10.13.4, a user is notified on the launch of an app that depends on 32-bit software. Age of empires 3 mac maps download. The alert appears only once per app.
When users attempt to launch a 32-bit app in 10.13.4, it will still launch, but it will do so with a warning message notifying the user that the app will eventually not be compatible with the operating system unless it is updated. This follows the same approach that Apple took with iOS, which completed its sunset of 32-bit app support with iOS 11 last fall.
Developers and users curious about how this will play out will be able to look at the similar process in iOS for context. On January 1 of this year, Apple stopped accepting 32-bit app submissions in the Mac App Store. Rocket league mac download free no survey. This June, the company will also stop accepting updates for existing 32-bit applications.

And before you say, 'Well, that's just the Mac App Store,' note that Apple also said the following this week:
If you distribute your apps outside the Mac App Store, we highly recommend distributing 64-bit binaries to make sure your users can continue to run your apps on future versions of macOS.

First off, there is now a Terminal command which will force an app to run in 64-bit mode, allowing its developer to see if it encounters any issues in what will eventually be a 64-bit-only environment. Apple has also made new diagnostic tools available for testing 64-bit compatibility in the newly released Xcode 9.3 beta.
These are Apple's notes on those Xcode tools:
The last macOS release to support 32-bit apps without compromise is macOS High Sierra. Make sure future releases of your app are 64-bit compatible by using new diagnostic tools in Xcode 9.3 beta and testing on macOS 10.13.4 beta. This version of Xcode also builds 64-bit apps by default. Philips hue sync app pc.
Xcode 9.3 also includes features to help developers address battery drain caused by their software. You can use the Terminal command to test which apps you currently use still need to be updated. Apple's instructions are as follows:
1. Launch Terminal
2. Execute the following command: sudo nvram boot-args='-no32exec'
64-bit test mode prevents 32-bit processes from launching. Launching an app that depends on 32-bit software results in a notification that the application can't be opened. Other types of software may fail silently, such as 32-bit versions of Dashboard and WebKit plugins, preference panes, and background processes.
Disable the test mode once the software is updated to work in 64-bit.
