You've probably been seeing alerts like this one:

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.


Go64 makes it easier to go 64-bit by helping you…

  • 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.
Which apps will stop working after Mojave and why?

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."


How do I find the 32-bit apps on my system?

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!
