Apple Releases Mac OS X 10.4.6 Update — Just as we were finalizing this issue, Apple released Mac OS X 10.4.6 Update, which appears to be a massive, miscellaneous bug-fix update. Numerous bugs and inconveniences that we’ve experienced are said to be eliminated, including a Mail crash, the mysterious "we are using special permissions" reports when repairing permissions with Disk Utility, the misbehavior of the Calculator percentage button, the Help Viewer blank window, problems saving Microsoft Word 2004 documents across a network, and many others. The update also includes iSync 2.2, which provides synchronization support for additional mobile phone handsets; however, iSync users should perform a full synchronization of all devices before installing Mac OS X 10.4.6.
As usual, you can use Software Update or download the update installer and run it manually; and in the latter case, you can download a delta updater (updates 10.4.5 to 10.4.6) or a combo updater (updates any Tiger installation). The updates are massive, with versions available via Software Update clocking in at near 46 MB, and standalone and Combo installers ranging from 65 to 191 MB. Apple also warns that (for reasons not revealed, but likely revolving around the login-related fixes) PowerPC-based Macs will automatically restart twice after the installation. The 10.4.6 update is available for both client and server versions of Mac OS X. [ACE]
