Access Issues for macOS Sierra Users on the Mac App Store
Apple introduced its macOS Sierra in 2016
Recent backend adjustments to the Mac App Store seem to have inadvertently cut off access for those using macOS Sierra and earlier versions. This disruption not only impacts new purchases but also affects users trying to re-download previously acquired software.
While the latest users of macOS Sequoia have experienced enhancements in their interaction with the Mac App Store, it has been reported that those on the older 2016 macOS Sierra can no longer utilize its features at all.
As brought to attention by tech blogger Michael Tsai, individuals running version 10.12.6 of Sierra are encountering error messages when attempting to log into their accounts. It remains unclear whether this issue is affecting all or just a subset of users, but increasing reports are being shared on Apple support forums and various social media platforms.
This problem seems to correlate with Apple’s developer announcement made in mid-January regarding modifications they would implement for app storereceipt certificates. These certificates serve as proof of purchase for applications available through the store.
In a statement aimed at developers, Apple warned that “your app might fail validation against its receipt,” which raises concerns about potential content accessibility disruptions for customers. The advisory provides instructions on how specific apps can be updated to circumvent such problems.
Currently, there is no similar advisory related specifically to issues concerning overall access within the App Store itself; thus, it may be reasonable to conclude that this malfunction might soon be rectified by Apple through an update.
The Legacy of macOS Sierra
However, it’s important to note that macOS Sierra has nearly reached its tenth anniversary since launch. This particular version was especially notable as it marked Apple’s transition from calling its operating system OS X to significantly branding it as macOS.
The Shift Towards 64-Bit Applications
With subsequent releases like High Sierra in 2018, Apple enforced a clear policy shift towards supporting exclusively 64-bit applications. This means any older software designed for a 32-bit architecture became obsolete following this update.
Accordingly, current trends show an ongoing migration toward newer systems and technologies as users adapt their workflows and applications accordingly—aligning with statistics indicating over half (54%) of Mac users now employ devices running versions beyond High Sierra or later according to recent surveys conducted among tech enthusiasts.
