How do I do this. I had a disc that did this on my old imac.
My iBook is taking forever to open or close Safari or shut down. Sounds like it's grinding to a halt. It's almost 3 years old and I have never done anything to it.

Any help would be appreciated

iBook G4, Mac OS X (10.4.11)

    Hi and welcome. Have you done some basics like running repair permissions from Disk Utility and then running verify disk from there also? If verify disk reports any problems, you then will need to startup from your install disc and run repair disk from Disk Utility to try to fix the problem.

    Is your Mac's internal HD very full? It is said you need at least 20% or so of free space to have things run well.

    I'm not very up on defragmentation on the Mac. It is a little controversial about whether it is needed or not. Maybe someone else will chime in or you can do a search of the discussions to find previous comments about it.

    thnx for reply
    I finally found Disk Utility and did verify & repair disk permissions and verify disk - the following is what it gave me
    "Volume Header needs minor repair
    The volume Macintosh HD needs to be repaired.
    Error: The underlying task reported failure on exit
    1 HFS volume checked
    Volume needs repair
    Disk Utility stopped verifying “Macintosh HD” because the following error was encountered:
    The underlying task reported failure on exit"

    I guess, I need a disk (of which, I can't find right now.)
    Thanks for your help

    Yes, you'll need to find your install CD/DVD and start up using that and then run disk repair in Disk Utility. That's the best next step.

    Until you find that disc, you might try using fsck according to this Apple article:


    The standard recommendation in this situation and all the time, is to make sure you have all valuable data backed up.

    P.S. When you say that your Mac sounds like it's grinding to a halt, do you mean you actually hear grinding noises from within? If so, you might be nearing a hard drive failure.

    Maybe someone else will chime in

    I'll chime!

    Apple KBase article [About disk optimization with Mac OS X|http://docs.info.apple.com/article.html?artnum=25668]

    Two different views about defragmentation:

    [Optimizing Disks Is a Waste of Time|http://db.tidbits.com/article/7254]

    [Macintosh OS X Routine Maintenance|http://www.macattorney.com/ts.html#Anchor-31774]

    There is a difference between defragmentation and optimizing. Defrag. makes files occupy contiguous space, optimizing puts things in a specific order. Techtool has a defragmentation feature. idefrag mentioned by another poster also does optimizing.

    I'm wondering if Safari is taking a long time because it has a bunch of caches and cookies and logs it is trying to read and store. Under the Safari menu there is an empty cache option. Under the security preferences you can show cookies and delete some (note, in doing so you may find some password protected sites will require you to log in again).

    alternatively try booting into safe mode (restart and hold down the "shift" key until you see the apple and spinning gear). I believe that too will run a disk check and fix any issues. and it can give you some more info if you are able to boot into safe mode and the OS / applications run smoother

    In the meantime you could try running Applejack.



    After installing, reboot holding down CMD+s, then when the prompt shows, type in one of the following commands:

    applejack auto restart
applejack AUTO restart

    Note the spaces between the three words!

    the difference between the two "sequences" are that in the second case (auto is typed in UPPERCASE) the caches are deep-cleaned. Not in the first sequence.

    Then let it do all 5 of it's things.

    At least it will eliminate some questions if it doesn't fix it.
    The 5 things it does are...

    Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.

    Of course, you can always interrupt the process or skip one or more of the five steps.

    Yes, I really must rephrase that and claim it as my own!
