Just last year, Apple made the transition from Intel to its own M1 chipsets. As a result, apps developed for x86 platforms like Intel’s processors cannot run natively on M1 chipsets, which means that developers will now have to start developing apps native to the M1 and future chipsets from Apple.
However, it seems that maybe Apple chose the wrong time to make the transition. This is because according to a study by AppFigures, it appears the developer interest in the Mac platform is starting to wane. Based on the figures, an average of 343 apps were submitted to the Mac App Store in 2021.
This is versus 2020 where it was around 392 apps averaged a month, which means that there are now less Mac apps being released. However, it is possible that due to the switch to the M1, developers are still working on getting their apps optimized for it which could suggest the slow down in submissions and releases.
Also, it should be pointed out that Mac apps can be downloaded outside the Mac App Store, so maybe just interest in submitting to the App Store is waning, especially in the face of Apple taking a 30% cut from developers. Apple’s macOS is far from being in any real trouble, but it’s probably something they’ll want to look into anyway.
