Security Update 2005-007 1.1 fixes 64-bit support

After issuing a security update earlier this week that broke 64-bit applications on the company’s operating system, Apple on Thursday issued a new patch to deal with the problem. Security Update 2005-007 v1.1 replaces Security Update 2005-007 v1.0 for Mac OS X v10.4.2. Users who have already installed v1.0 on Tiger systems should install v1.1, according to notes accompanying the update.

The new update provides a combined 32- and 64-bit version of LibSystem to replace the 32-bit version that was delivered in v1.0. According to Apple, no other changes have been made in version 1.1.

News of the 64-bit application problems came as users installed the original update issued by Apple on Monday. Wolfram Research gave its customer a script to disable its 64-bit optimized Mathematica 5.2, so it worked in 32-bit mode until Apple released a fix for the problem.

The update is available from the Software Update control panel or Apple's Web site.
