Apple has finally pulled the delta update for Mac OS X 10.7.3, a release that was supposed to fix bugs and other problems but instead caused major problems to some users, such as the CUI errors and other application issues. Instead of downloading the smaller delta update, users are now made to download the combined update, meaning a bigger download of 1.34GB, almost double the original update’s size of 730.6MB
While the issues weren’t happening to everyone, a large number of users had OS-breaking problems, including myself. If you don’t want to risk anything, you should always wait a week after an update until the all-clear is given. And while this update is probably safe, you might want to wait if you’ve got important work to do.
