Apple late Wednesday night fixed a glitch in its recent security update that prevented Tiger users from running 64-bit applications. As reported yesterday, the initial version of the Security Update 2005-007 1.0 accidently disabled 64-bit computing under Mac OS X 10.4.2, while addressing nearly three dozen other security exploits. Security Update 2005-007 v1.1, now available for both Client and Server editions of Tiger (via the web and Software Update), replaces Security Update 2005-007 v1.0 for Tiger systems Mac OS X v10.4.2. Apple recommends that users who have already installed v1.0 on Tiger systems to install v1.1. Version 1.1 of the update "provides a combined 32- and 64-bit version of LibSystem to replace the 32-bit version that was delivered in v1.0. No other changes have been made in version 1.1," according to Apple's documentation.
