TUAW reports that Apple will be scaling back on systemwide “hotkey” apps, which allow users to call up other apps and functions, in the Mac App Store as of June 1, the same date the company’s sandboxing requirements are scheduled to go into effect.
Apparently, Apple will allow hotkey apps that are already in the Mac App Store before June to offer only bug fixes after that. New sandboxed apps and any apps that add features (i.e. non-bugfix releases) will not be allowed to support hotkeys.
TUAW has been told that Apple will be rejecting all MAS apps with hotkey functionality starting June 1, regardless of whether the new features are hotkey related or not. Basically, if you’re developing one of those apps, an app that assumes you can still add hotkeys, don’t bother submitting it to the Mac App Store.
Various cross-scripting and macro apps will be affected by the change, which appears to be related to the sandboxing requirement that limits what applications can do on other parts of users’ systems.
With the sandboxing requirement set to go into effect two weeks from now after several delays, a number of developers are undoubtedly working to make sure their apps are in compliance with the new rules. Just today, Pixelmator announced that it has updated its image-editing app to meet sandboxing requirements, making it one of the first high-profile apps to make the move.
