You might want to check out the thread here:

Apple Discussion Thread

It looks like a good fix to the slow boot problem.

[jocker]

hey cheers - worked like a charm!

[mcsjgs]

It turns out that all might not be roses with the fix. There is another discussion thread with a possibly safer command and an undo command for the first post here:

Apple Discussion Thread 2

The problem seems to be that the additional file generated by the first fix might conflict with future OS X updates. Hence the remove command. You'll have to read the thread fully to get the back and forth.

[mcsjgs]

Here is a summary and all commands are on a single unbroken line (no returns, no line breaks in Terminal regardless of how they appear here). You will need to enter your administrative password in Terminal followed by a return after the command:


1. Command creates extra file, speeds up boot times, but might screw up future updates:

sudo cp /System/Library/Extensions/BootCache.kext/Contents/Resources/BootCacheControl /usr/sbin

2. Remove this command before installing any future OS X updates:

sudo rm /usr/sbin/BootCacheControl

3. Possibly safer command that uses link (but apparently not recommended by Apple Technical Support):

sudo ln -s /System/Library/Extensions/BootCache.kext/Contents/Resources/BootCacheControl /usr/sbin

Edited: Used BBEdit Lite to save, and I cannot see any underscore characters. If you see an underscore character, change it to a space.

Edited again: I looked at this in Safari, Mozilla Firebird and Camino. I can't see any underscore chracters. I don't use IE or Netscape, so can't help you there.

mcsjgs: Those are NOT underscores in those commands. They should be spaces!

I'm not seeing underscores. I'm looking at the post with Safari. Let me check with another program.

I'm looking at the post with safari and see underscores right before /usr/sbin too.

[mcsjgs]

Crap, you're right. I'll change and repost. Sorry.

Edited: Done.

[mcsjgs]

I apologize for that error. Somehow, in copying and pasting the post between my computer and MacNN's board, two characters were changed from spaces to underline characters. In the original, I did a search and there are no underline characters. Don't know how it happened (an HTML thing?), but I apologize for the error.

im sure apple technicians knew what they said. i don't think you'd have to to the undo command

sudo rm /usr/sbin/BootCacheControl

before installing 10.3.3 as the technicians will probably fix that in the update (but possibly not the boot time). anyway, im about to go and try the cp command and ill try to post boot time before the command, the first boot, and the second boot.

[spitty27]

3:21 before patch
3:20 on first restart
2:45 on second restart

One Way:

sudo� cp� /System/Library/Extensions/BootCache.kext/Contents/Resources/BootCacheControl� /usr/sbin

To Remove:

sudo rm /usr/sbin/BootCacheControl

Another Way:

sudo ln -s /System/Library/Extensions/BootCache.kext/Contents/Resources/BootCacheControl /usr/sbin

not that bad...considering the setup (look at sig)

I just tried to remove command and it came back with no such file or directory.

Before;

Dual 1.8 G5 Approx 1:15
1.25 G4 Powerbook Approx 1:45


After;
Both at about 45 secs!!! Woohoo

I can't get to the apple discussion board to get full details but the tip seems to be a bunch of BS. Look in /etc/rc to find

--snip--
BootCacheControl=/System/Library/Extensions/BootCache.kext/Contents/Resources/BootCacheControl
if [ ! -f $BootCacheControl ]; then
BootCacheControl=/usr/sbin/BootCacheControl
fi
if [ "${SafeBoot}" != "-x" -a -x "${BootCacheControl}" ]; then
${BootCacheControl} start
fi
-- end snip--

It's already checking for BootCacheControl inside BootCache.kext. If it exists it'll execute from there otherwise fallback and use /usr/sbin/BootCacheControl if it exists and is executable.

Look at my answer in the other thread. You really shouldn't cross-post, especially wrong information.

[mcsjgs]

My boot times decreased dramatically from over a minute to less than 15 seconds.

I used the cp command then got nervous because of the extra file. Removed it.

Then ran the ln command. Same fast boot times. Literally from "checking disks" straight to login. Great improvement.

These commands solve half the equation. Boot times are now back to fast. But from login to full desktop is still slow. On my machine, every startup item is undergoing a prebinding routine which slows things down. Don't know why. Forced prebinding does not solve the problem.

[jgcan]

Wow! Back to pre-10.3.2 boot times with that fix (16-17 turns of the spinning thingy instead of 30). But still get the beachball after the menubar, which I did not before 10.3.2.

Anyway, boot times are quite slow with the PB 17" 1.33 compared to some other machines. I always got no less than 16 turns of the spinning thingy (on Apple gray boot screen) since I got the machine, pre-installed with Panther.

Now, I am confused, do I have to remove anything I did before the next upgrade (10.3.3)?

Thanks all (new switcher here).

If you used the "cp" command, you should do the "sudo rm /usr/sbin/BootCacheControl" before installing the next OS upgrade.
If you used the "ln -s" command, then you don't have to remove anything.

[Fonzie]

Is doing this perfectly safe ?

even if doing the "sudo In -s .... " thingy ?

Ok, I did the cp one, now I want to change it now, so I just do:

sudo rm /usr/sbin/BootCacheControl

and then the ln -s one? Need a reboot between the two?

Thanks

I've tried all of the following:

1. Command creates extra file, speeds up boot times, but might screw up future updates:

sudo cp /System/Library/Extensions/BootCache.kext/Contents/Resources/BootCacheControl /usr/sbin

2. Remove this command before installing any future OS X updates:

sudo rm /usr/sbin/BootCacheControl

3. Possibly safer command that uses link (but apparently not recommended by Apple Technical Support):

sudo ln -s /System/Library/Extensions/BootCache.kext/Contents/Resources/BootCacheControl /usr/sbin

The first command worked just fine and I decided to remove it and try the second command. So far I am unable to make the sudo ln -s command work. Any suggestions?

Apple's Software Update doesn't respect symbolic links. (It'll most likely just delete the symbolic link if it finds it and needs to replace it)
