Apple no longer allows unofficial installation of iOS apps on ARM Macs






We expected it and it is now done: Apple has decided to lift the possibility of unofficially installing iOS or iPadOS applications on Mac ARMs.

Since the new Macs are now based on an ARM architecture with the M1 chip, they can theoretically accommodate applications designed for iPhones and iPads. In practice, however, it is the publisher of the application who must authorize this installation or not.



The end of sideloading on Mac ARM

In unveiling its new Macs, Apple explained that developers could allow users to install their mobile applications on macOS. By default, these are immediately available and the publisher refusing this new possibility must manually go to the App Store Connect to remove it from macOS.

However, for a while it was possible to recover the IPA installer file of the iOS or iPad OS application and then run it on macOS without the consent of its editor. This practice of sideloading could in particular be carried out via tools like iMazing.




 According to 9to5Mac, Apple made changes on the server side to remove this possibility, if the application in question is not available within the Mac App Store. This is valid for ARM Macs running macOS Big Sur 11.1 or 11.2 beta. In the latter case a new message appears explaining the reason for the change.

Editors still cautious

Note, however, that applications already installed or downloaded still work today. Still, several reasons can push a publisher not to want to allow the installation of its iOS or iPadOS application on macOS.

While it may be convenient to run an application in a small form factor, the developer may wish to encourage downloads of their software specifically designed for macOS. Some publishers also prefer to wait until they design an application that is truly compatible with macOS in order to provide a better user experience.

It is also worth pointing out that some features have been strictly intended for mobile use on iPhone and iPad. Netflix, for example, offers caching of movies and series. At present this is not yet the case with the web application.

Some publishers marketing their apps on iOS and iPadOS are also dependent on an advertising model for their web app on MacOS. There would therefore be a shortfall on the Mac. Publishers can also choose to separate mobile and desktop advertising metrics to optimize the latter.

We imagine that at the next WWDC conference Apple will highlight these multiplatform applications and share testimonials from publishers who have found the right balance to put in place.
