The Mac App Store's future of irrelevance
Postbox's exit from the Mac App Store should sound very familiar to anyone who buys Mac software. If you read between the lines a bit, I think the real story there is one we've seen a lot since June 1: they tolerated the App Store's lack …
Context & Ripple Effects
Postbox’s departure adds to a record of Mac-software developers questioning the store model, including Rogue Amoeba’s earlier exit and the concerns collected when developers weighed the Mac App Store’s trade-offs. Apple’s 2011 move away from boxed software in education made viable digital distribution channels more important, not less.
The significance is not Postbox alone but the mismatch between a growing Mac audience and a store that some established developers did not regard as a workable primary channel.
First-order effects
- Postbox leaves the Mac App Store, reducing the store’s catalog for customers seeking desktop email software there.
- Postbox regains distribution outside the store’s rules and release process, while Apple loses a developer willing to distribute through its channel.
Second-order effects
- Other Mac developers evaluating the store gain another concrete example that direct distribution may be preferable when the store’s constraints conflict with their products.
- Apple’s push away from boxed software leaves Mac developers more dependent on either the Mac App Store or their own online sales and support infrastructure.
Third-order effects
- If developer exits continue, the Mac App Store risks becoming less representative of established Mac software, weakening its value as the default discovery and purchase channel.
- The episode points to an SDK governance gap: platform owners can standardize distribution, but restrictive rules can shift software businesses back toward direct customer relationships.
The trend: Mac software distribution is moving toward a contest between Apple-controlled storefront convenience and developers’ need for control over product capabilities, sales, and support.
