macOS Big Sur: Apple (re)bans unauthorized iOS applications

Apple first blocked the installation of unauthorized iOS applications on Macs under Big Sur a month ago. But four days after this ban was put in place, thislast one was up. If we thought that the subject was closed since then, Apple is once again making the weather vane in this matter.

As reported by 9to5Mac, the latest version of Big Sur (11.2) which was released last week once again enables server-side blocking. Further tests showed that this ban was also effective on the current beta version of macOS 11.3.

Apple's M1 chip shares a fairly similar architecture to the Ax series chips (used in iPhones), making it relatively simple to run existing iOS apps on the desktop platform. iOS developers who do not wish to distribute their products on macOS, whether for technical or marketing reasons, can however refuse to feature their iOS software on the Mac App Store. But users could still install these unauthorized iPhone/iPad apps on macOS, until Apple made this possibility obsolete.

Solutions?

Until now, you had to use .ipa files to install iOS applications on Mac, such as Instagram for example. But these are now no longer readable. Under the latest version of macOS Big Sur, a message is displayed instead of said application: “This application cannot be installed because the developer did not intend to run it on this platform .”

The reasons which motivated this choice on the side of Cupertino are obvious, it is a question of respecting the choice of the developer who does not necessarily want his iOS app to be used on macOS. It therefore seems quite certain that Apple will no longer turn back on this subject in the future. Users will therefore have to get used to no longer using these unauthorized applications on Mac, or wait for developers to authorize their iOS application on Mac, or for them to offer a dedicated macOS application for their service.
