Apple has created a hole that allows users to sideload iOS and iPad applications on the M1 Mac that were never intended to run on desktop, 9to5Mac reports. The server-side change ensures that only applications that the app developers have flagged as optimized for Mac.
At the end of last year, Apple launched its first Mac, named M1, running on its first ARM-based custom CPU, unlike the Intel chips used in Macs for many years. These new machines included the entry-level 13-inch MacBook Pro, MacBook Air, and low-end Mac Mini.
Since those machines now share an architecture with iPhones and iPads, including ARM-based chips, it became possible to natively run iOS and iPadOS apps on Macs that were equipped with the M1 chip. Apple supported this by listing an iPhone and iPad app that passed an automated test on the Mac App Store, provided the developers opted not to list the app.
However, many developers did Quit for any reason: because they didn’t feel that the app provided a good user experience on a laptop or desktop; As they provide preferred alternative ways to access services or content on a Mac; Because they do not have time to support an additional platform; Or a number of other reasons.
In those cases, apps did not appear on the Mac App Store. But a few months ago, a Reddit user shared a way of sideloading apps on M1 Macs that use an app’s IPA file from a connected iOS or iPadOS device using third-party software, such as iM iM for Mac. , Was sharing.
According to 9to5Mac, however, Apple has now “flipped the required server-side switch” to block this method. The change affects Macs already running MacOS Big Sur 11.1, and the same applies to Macs running 11.2 beta. In fact, it also gives an error message on the latter: “This application cannot be installed because the developer did not intend to run on this platform.”
Apple has introduced this change for several reasons. For one, an alternative version of the IPA file method described above can also be used to validly and sideload pirated versions of apps rather than files from versions installed on iOS or iPadOS devices. In addition, Apple and developers may find that these applications provide a poor user experience on macOS, and they can be a support or security headache.
