Time Machine and AirPort Update 1.0 prevents Mac OS X 10.5.2 combo installation; fix
A trusty solution blocked; and a workaround.
It appears that installation of Time Machine and AirPort Update 1.0 -- which instates the ability to use Time Machine for AirPort-connected USB disks ("AirDisks") -- changes the build number of Mac OS X 10.5.2, disallowing reinstallation of the Mac OS X 10.5.2 combo updater. Reinstallation of combo updaters is a highly effective workaround for a variety of problems after significant system updates.
The updated system build causes the error message:
- "This volume does not meet the requirements for this update."
when attempting to re-apply the combo updater.
The fix is to trick the Mac OS X installer into thinking you are using an older build by launching the Terminal (located in /Applications/Utilities) and entering the following command:
- sudo defaults write /System/Library/CoreServices/SystemVersion ProductBuildVersion 9C31
You should then be able to properly re-apply the Mac OS X 10.5.2 combo updater. NOTE: After re-installing the combo updater, you must also re-apply the Time Machine and AirPort Update 1.0 and Security Update 2008-002 (v. 1.1 if applicable). Otherwise you may encounter build number mismatch issues in various applications.
You should only enact this fix if there is a high probability that re-applying the Mac OS X 10.5.2 combo updater will resolve an issue manifested by Security Update 2008-002 or Time Machine and AirPort Update 1.0.
