Apple has announced that macOS 10.14 will be the last version capable of running 32-bit applications.
As Apple finalizes its transition to all-64-bit code, Mojave and High Sierra present an alert like this when you launch a 32-bit application. While it's not a crisis at present, you'll need to update or upgrade those applications before you update to macOS 10.15 later this year.
- Take an inventory of the apps on your Mac and see which ones are still 32-bit.
- Go to a developer's website or search the web for update or upgrade information.
- Keep track of upgrade costs so you can plan your spending to get all the upgrades you need.
Any app that's built with Apple's 32-bit software libraries will need to be updated so it will run in 64-bit mode. These are primarily older applications, but some newer specialty apps are also still 32-bit.
As Apple says, 'The technologies that define today's Mac experience—such as Metal graphics acceleration—work only with 64-bit apps. To ensure that the apps you purchase are as advanced as the Mac you run them on, all future Mac software will eventually be required to be 64-bit.'
Apple's support article explains how to use the built-in macOS System Report to identify 32-bit apps on your system.
However, once they've been identified, looking them up and locating the developers' contact information can be a painstaking process if you've got more than a few. In addition, the System Report doesn't account for apps that are themselves 64-bt, but that contain 32-bit plugins, frameworks or services. These apps may or may not run correctly on macOS 10.15. That's why we made Go64!
