During yesterday, an important certificate of OS X has expired, users being unable to make updates for the official applications Apple Lossless Audio CODEC (ALAC),, but also to upgrade the operating system. It seems that Apple Lossless Audio CODEC (ALAC), neglected to change the certificate that expired yesterday and despite an expected silence from those in Cupertino, the problem could be solved extremely quickly during tomorrow.
The certificate that expired in OS X yesterday is responsible for authenticating connections made to Apple's Mac App Store, and in its absence, only updates for some third-party applications can still be made. Considering that we are talking about an important problem that affects all Mac owners who have the Mac App store, it is quite unusual for Apple not to update the respective SSL certificate on time, so if you encounter errors during updates, you know where comes the problem.
