Macos high sierra 10.13.4 already shows warnings when opening 32-bit applications

After the recent release of the new update to Apple's desktop operating system, macOS High Sierra 10.13.4 (beta), the Cupertino company has started with its plan to eliminate 32-bit applications on all Mac computers, and that is that Apple has promised that macOS High Sierra will be the "latest version of macOS that can support 32-bit applications."

The goodbye to 32 bits begins

After installing macOS High Sierra 10.13.4 version 10.13.4, when users open an application that is 32-bit, the system displays a warning about its future incompatibility with the macOS operating system.

This is the first of many warnings that Apple plans to provide users, as it is part of a plan aimed at ending 32-bit Mac applications. However, this initial warning will only be shown once for each of the affected applications.

Apple's efforts to phase out 32-bit applications on Mac computers are part of the roadmap started by the company when it ended the compatibility of such apps on iOS devices. In iOS 10, Apple provided increasingly insistent warnings to let users know which apps would not work with future versions of iOS before they gradually and de facto began to be removed in iOS 11.

As of January 2018, all new applications submitted to the Mac App Store must be 64-bit, while all application updates must also be 64-bit by June 2018. The next release of macOS after High Sierra will include an "aggressive" 32-bit application warning plan before they are removed entirely.

Once 32-bit applications are progressively removed from Macs, they will no longer be able to be used at all, so users will need to find 64-bit apps with which to replace 32-bit apps, in case of that responsible developers do not update them.
