speed things up? when i restart my pb 15" 1.25, it takes about 2 1/2 minutes to get from the first tone to my desktop image. i understand that some settings will affect boot times, but this seems a bit excessive. it takes about 2 min just to get to the first dialog box with "initializing internet connections", etc. so is this normal for the pb or can i do something to help it out? i've got 512 ram installed on the 80 gig 4200 rpm drive. thanks for any help.

yeah Mine is pretty much the same. I would love some help on this..
I have a 1.25ghz 15" Powerbook with 80mb 5400 HD and 768mb of Ram.
It takes mine 2 1/2 minutes to boot up..

It slowed down after I installed the 10.3.2 update.

1. Launch Terminal

2. Type
sudo cp -p /System/Library/Extensions/BootCache.kext/Contents/Resources/BootCacheControl /usr/sbin/

You can copy and paste.

3. Key in your user password and hit enter.

4. Exit Terminal

5. You need two reboots to see the difference.

I pulled this off of the apple forum, I haven't tried so use it at your own risk but it seems to work for most poeple.

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

I don't know if that will come through but it's:

sudo<space>cp<space>-p<space>/System/Library/Extensions/BootCache.kext/Contents/Resources/BootCacheControl<space>/usr/sbin/<enter>

It asks you for your admin password.

Edit you beat me to the punch

the command is safe but you should use is

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

this makes a symbolic link to the BootCacheControl program that is called twice during startup... you will have to restart twice

typoon · Feb 9, 2004, 02:17 PM

There is a little script that you can download. It IS safe. Called speedstart you can get it from macupdate.com

wy4tt · Feb 9, 2004, 02:36 PM

awesome. thanks all! i'm not with my pb right now to try it, but if it cuts down on boot time, i'm happy. btw, is there an advantage to using the command vs the script?

i imagine they do the same thing... i like the command i posted because it doesnt actually move any files unlike the cp

ryanhugh · Feb 9, 2004, 06:34 PM

wow....I just did this and its made a huge difference in start up time! I would say it doubled it at least....thanx!

wy4tt · Feb 9, 2004, 08:49 PM

wow. thank you all once more. my boot times are now a minute and a half shorter! great stuff. makes me wonder what other little tricks can enhance an already incredible little machine...

jorgem4 · Feb 10, 2004, 07:40 AM

I did it too and it works great! Thanks....

How offten should one apply this command? Just every time the startup is slow? Are there any other commands that would help improve the health of my Mac?

Thanks

You shouldn't need to do it more than once.

I have ordered from Apple online store two Macs: one pb 15" and one iMac 17" (yep, big investment and switching my whole household to Mac)

I wonder if this little script will work on any models (like my case, the iMac desktop).

May I also know what it actually does to speed up bootup time, like eliminate some unnecessary steps or what?

Thanks for helping out this new switcher.

jorgem4 · Feb 11, 2004, 07:55 AM

Good job on switching!....I really don't know **** about the script...just wanted to say congratulations on the switch.

You will see....one you go Mac, you never go back.

Well, you could try using sleep instead of booting.

A PowerBook wakes from sleep in about the time it takes to open the lid. No more long boot time.

And battery use is very low when in sleep. Just close the lid and it will go to sleep. Open the lid again and you're back to work.

Yes this will work for all your machines running 10.3.2. I used it on my upgraded G4450 and have recommended it to other with different machines with no ill effects

BootCacheControl gets called twice during startup, this just makes the call faster since it looks in /usr/sbin first

dagaz · Feb 13, 2004, 05:11 AM

This symbolic link was apparently taken out by the 10.3.2 update but has since been replaced by the Security Update 2004-01-26.

yep. sleep is great with the pb. i rarely restart mine, but when i did...it seemed a little long. but no more.

I've seen this before, but how exactly does copying the BootCacheControl to /usr/sbin help speed up boot times? Just out of curiousity.

chabig · Feb 16, 2004, 09:55 AM

I haven't shut down a Mac in over two years. Sleep is the way to go.

webb3201 · Feb 16, 2004, 11:17 AM

I never shut mine down either. Other than reboots due to updates, my machines are up 24x7. The sleep mode allows for little to no battery loss and 5 second or less startup times. I can pull my machine out of my bag and grab a phone number as quickly as I can with my PDA (almost)
