Download and install Mac OS X 10.3.3 Update or later to address this issue.
If you're not ready to update, these tips can help:
If the computer's startup time is longer, follow these steps:
- Open the Terminal (/Applications/Utilities/).
- Type the following (on a single line). Alternatively, copy the text below and paste it into Terminal.
sudo cp -p /System/Library/Extensions/BootCache.kext/Contents/Resources/BootCacheControl /usr/sbin/
Note: There is a space before "/usr/sbin/".
- Press Return.
- When prompted, enter your admin password.
Important: If the following message appears in Terminal, verify that step 2 was performed correctly. If so, you do not need to use these steps because your computer is not affected by this issue.
Message: "cp: /System/Library/Extensions/BootCache.kext/Contents/Resources/BootCacheControl: No such file or directory"
- Restart your computer.
Note: The first startup after this will still be longer. Subsequent startups will be faster.
