Breaks the every-two-weeks pattern
Just ten days after the previous release of build 11E46, Apple has posted a later version of the upcoming 10.7.4 update for developers, listing no known issues. The developer-only 11E52 breaks the pattern of around two full weeks between updates, and features a version number smaller in difference than the previous release, which suggests that final release may be nearing. This is the fourth version of OS X 10.7.4 to be offered to developers for testing.
As with previous updates, Apple warns that testers cannot revert to any previous version once the new build has been installed, and expects developers to use the OS only on machines that can be erased if a serious flaw is discovered. The combo update requires 10.7 or higher (including any of the previous seed builds), and the delta (in-place) update requires either 10.7.3 or one of the previous seed builds.
Testers are asked to focus on graphics, iCal, Mail, Time Machine and printing when looking for issues. Full bug reports, including crash logs, backtraces or Activity Monitor samples depending on the severity of any problems found. A Mac OS X developer account is required to gain access to the unreleased betas.
