Failed software updates on a Mac computer running the Mac OS X 10.5 operating system sometimes generate a "configuring installation" error that prevents the updates from installing correctly. One way to reinstall the update is to delete the files in the Updates folder under the Library directory. Make sure you delete the specific update files and not the actual folders themselves.
Click the Finder icon in the computer's dock, followed by the computer's hard drive listed beneath the Devices heading.
Click the Library folder icon, followed by the Updates folder icon.
Select the first item in the Updates folder, press and hold the Shift key and then also select the last item in the folder to highlight all items.
Click the highlighted items and drag them into the Trash icon in the computer's dock. Right-click the Trash icon and select the Empty Trash option from the context menu to delete the Library/Updates folder contents.
Tips & Warnings
- After deleting the partially downloaded files, run the Software Update tool again to re-download and install the missing updates.
- To avoid this issue, download and install the Mac OS X 10.5.6 update or later.
