ARS Technica: There's a reason many of us here at Ars wait a few days (or in some cases, weeks) after an OS update before installing it: reports of problems after upgrading to Mac OS X 10.7.3 have begun multiplying since its release on Wednesday afternoon. But don't worry—you don't have to wait for Apple to issue a fix, as reinstalling with the 10.7.3 Combo updater seems to take care of the various upgrade issues.
