A developer training firm named Shiny Development has been tracking waiting times for the App Store review process as closely as it can, and it has bad news for would-be app developers: The waiting times for the Mac App Store are growing longer. In the last six months or so, the waiting time for getting a Mac App published has gone from under seven days to almost as high as a month, according to Shiny’s data. Apple’s process is largely closed off—there is a little bit of information for developers on the main dev Web site, but otherwise Shiny has mostly gathered this information from the various developers it tracks and corresponds with online.
It’s no wonder that Apple doesn’t report the average review time for Mac apps the way it does for iOS ones. And it’s scary as a developer to think that you could ship a bug (or have Apple ship an OS update that introduces one). You work as quickly as possible to get a fix ready, and then Apple sits on it for a month—or longer if you’re unlucky enough to have one of the above-average review times. Even after waiting, there’s no guarantee that your update will be approved. Recently, Apple has rejected apps for not conforming to new, unwritten requirements, e.g. relating to 1024×1024 icons that no user will really see.
