The first time you use the Software Update control panel, it creates an installation log file named "Software Update Logs." This log resides in the Preferences folder. Use Sherlock 2 to find the log file. The name of each software update installed, as well as the date and time of its installation, is recorded in the log file.
To read the log file, download Automatic Update Software 1.2 from Apple Software Updates (
http://www.apple.com/swupdates/). Automatic Update Software is an alternate name for the Software Update control panel and its associated files.
Once your software has been updated, you may read the log by following these steps:
1. Open the Software Update control panel.
2. Choose Display Log from the Update menu.
Note: Some installers also place an Installation Log or Read Me file on the computer's hard disk.
