Mac OS X: Longer Startup Time After Installing Mac OS X 10.3.2 Update

In some cases, your computer may take longer to start up after installing Mac OS X 10.3.2 Update. This can happen if you update to Mac OS X 10.3.2 incrementally (from Mac OS X 10.3.1, for example), but does not happen if installing from a Mac OS X version 10.3.2 Install disc.

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:

  1. Open the Terminal (/Applications/Utilities/).
  2. 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/".

  3. Press Return.
  4. 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"

  5. Restart your computer.


Note: The first startup after this will still be longer. Subsequent startups will be faster.
