Apple apologizes to developers for recent ‘damaged’ Mac App Store apps bug, says OS X update coming with fix
Apple has emailed developers about the recent damaged apps bug affecting a sizeable proportion of the OS X user base with some getting repeated errors on app launch. Whilst a reboot should be enough to invalidate and reload the certificate cache for most people, there are some weird edge cases. Apple says that a permanent fix for the caching issue will be included in a future OS X software update.
The email is effectively Apple apologising to developers for the store platform problems, which caused many customers to understandably, but incorrectly, point blame at the app developers, not Apple.
