Mac users faced trouble with their apps overnight after the security certificate Apple uses to prevent piracy expired late on Wednesday.
Applications downloaded from the Mac App Store were temporarily unavailable from 10pm UK time, when a security certificate expired, five years after its creation, with no replacement immediately available.
Even once Apple fixed the error, issuing a new certificate for the apps (with an expiry date of April 2035, this time), users were still faced with problems. Those who could not connect to the internet couldn’t verify the new certificate, while those who had forgotten their password or couldn’t log in to iCloud for some other reason are also unable to use the downloaded apps until they can log in to the service.
My tweet from yesterday seems apt here. Unbelievably incompetent.
