Mac OS X Speed Up Command Works

, at least it did for our PowerBook 2000 (Pismo) but YMMV. Posted by Donna Armsworthy over the weekend on MacFixIt's Forum,

    1. Close all running applications.

    2. Open the Terminal application in the Utilities folder of OS X's Applications folder.

    3. After the login text, type "sudo update_prebinding -root /" without the "s but don't forget the spaces after "sudo" and before and after "-root".

    4. Hit the Return key. You should see a warning and a Password request. Enter your Password and hit the Return key. You should see lines of text being generated as the number of files to be bound are counted (we had 1055), then more lines of text as the files are bound 10 at a time. It takes about 5-10 minutes.

    5. When it's done. Close the Terminal application and restart. You may have to reset some preferences. We had to reset which Mac OS 9.1 system folder to use for Classic Mode.

Many subsequent posts claimed it sped up application launches but some stated that they could see no difference. There were no negative posts so we tried it and are happy with the results.

Do NOT do this if you do not like to experiment and are not willing to assume all the risks associated with doing so. We are not certain what all the ramifications are nor why or when this command works. While our Pismo is running Mac OS X faster (mainly application launches and window resizing and minimizing) we guarantee nothing. However, if you do it, let us know your computer specs and how it worked for you.
