Kernel_task ... what's that?
Something called kernel_task is running, and Activity Monitor shows its taking up 7 - 12% of my small cpu in my Yikes! G4/450 (ocd).
What's this? Running 10.4.11 on my oc'd Yikes!.
Machine Name: Power Mac G3 (PCI graphics)
Machine Model: PowerMac1,2
CPU Type: PowerPC G4 (2.6)
Number Of CPUs: 1
CPU Speed: 450 MHz
L2 Cache (per CPU): 1 MB
Memory: 1 GB
Bus Speed: 100 MHz
Boot ROM Version: 1.1.2f2
Some information bits about 'Kernel' can be read in the book review:
"A practical guide to Unix for Mac OS..." - google book search:
http://books.google.com/books?id=o9K8KEQic5sC
As a casual user of the computer and its OS, you may never need
to know much about the computer's system core elements; but
there are Developer pages accessible directly in Support, if one
asks the correct search question to get there - - among others.
Technical Note TN2063: Understanding and Debugging Kernel Panics:
http://developer.apple.com/technotes/tn2002/tn2063.html
If you have a real issue with a kernel (short of booting into OS 9
and throwing away a then-visible part of OS X) you can generally
expect it may be a panic. Between the above link to understand
what is going on, and another site with more troubleshooting in it,
the situation as you describe it, is one of curiosity and not urgency.
More about user-level kernel issues (the kernel panic)
"Resolving kernel panics" http://www.thexlab.com/faqs/kernelpanics.html
{Outside of issues known by this ^ name, and several symptoms,
the average user experience with the kernel is an invisible one.}
In any event...
Good luck & happy computing!

I'm note a firefox geek, but ever since my friend told me to install NoScript I can not access my msn and hotmail page. It tells me that Java Script is required, what ever that is. What do I do next. Do I uninstall the No Script. Thanks Ed edit
DetailsYou are on Windows 2000, you do not have a "Firefox" button, and should consider yourself to be fortunate in that you still have menus and don't have to do anything to get the menus back instead of the "Firefox" button. (The same applies to Windows XP users).
Use the "File" menu to get to Import. You are not on Windows 7 or Vista, and don't have to put up with the nonsense added for Aero.
If you want the "Firefox" button you can get it with View -> toolbars -> (uncheck) Menu Bar. The menu bar and the "Firefox" button were supposed to be mutually exclusive (which is impossible in some cases without being incompatible).
Once you are using the "Firefox" button ...
Use the "Alt" key to view the menu bar (temporarily) containing File, Edit, View, History, Bookmarks, Tools, and Help. On Windows 7 and Vista, the menu bar was hidden by default in Firefox 4 and above. These menu items are more or less available under the "Firefox" button which has the most used of the built-in Firefox menu items available in a different format.
To get back to having menus again. "Firefox" button -> Options (second column) -> (check) Menu Bar
You can make '''Firefox 7.0.1''' look like Firefox 3.6.*, see numbered '''items 1-10''' in the following topic [http://dmcritchie.mvps.org/firefox/firefox-problems.htm#fx4interface Fix Firefox 4.0 toolbar user interface, problems (Make Firefox 4.0 thru 8.0, look like 3.6)]. ''Whether or not you make changes, you should be aware of what has changed and what you have to do to use changed or missing features.''

When I click to pay my songs in the library they will not play and it shows a circle with an exclamation point within it. What does that mean, how do I fix it, and how will it play my songs again? They used to play before on my Iphone4 with no problem, but since I upgraded to the Iphone4s there is an issue.
I am having the same problem. I have just tried this. Unplug iphone > open itunes > delete all music from itunes library > close itunes > re-open itunes > add music from original folder > plug in iphone > select songs > press sync > unplug iphone using eject button onscreen > checked phone .... still nothing in music folder on phone. On itunes the "On this iphone" tab the songs remain there but greyed out.

I just downloaded itunes onto my new laptop and I am trying to burn songs onto a cd that I had purchased previously and I am getting an error message that states I must authorize this computer. What does that mean?
If the computer's running Mac OS X, move the cursor to the very top of the computer's screen, click on Store, and choose Authorize this Computer.
If the computer's running Windows, press the Alt and S keys and choose Authorize this Computer, or click here, follow the instructions, click on Store in the menu bar, and choose Authorize this Computer.

I have a ipod classic 160GB and it's not showing any music anymore, but there is still showing 7GB of memory being used, and I don't have it backed up on my itunes, since I had to put a new hard drive on my computer. Any suggestion to find out whats on that memory or to get it the music back, there is approximately over 1400 songs on it?
What is the memory being used by, is it Other? If it is, that means the iPod can no longer read the music, so it has put it all in "Other".
The usual fix for this is to allow the iPod to Sync with its iTunes Library. If that doesn't work, the next option is to Restore the iPod using the Restore command in iTunes, on the Device/Summary pane.
Unless you are very (very) lucky, I suspect that you are going to have to Restore your iPod. Restoring will remove everything form the iPod and put back onto it only what it finds in your iTunes Library, which you say is currently empty.
If you have to rebuild your Library after this issue, by adding all the music back again, this is going to be hard to hear, but for the future, you may want to consider always having a backup of your library. The easiset way to back the Library up is;
if the Library is small enough, burn it to a DVD, as digital files, not a "music CD".
If your Library is too large for a DVD, buy yourself an external hard drive and copy the Library onto the drive. Remember to update the backup every so often. -

my computer crashed and I had to re load my operation system. now, when I try to open my itunes all I get is a message that says "can not be read because itunes was created by a newer version" what does that mean and how do I correct it. I need my music back!
As iTunes is uopgraded the newer versions require that the iTunes database be upgraded to match. It sounds like you now have an older version of the sftware attempting to load an upgraded library which it can't do.
What version of OS X are you running?
What version of iTunes are you currently running?
What versions were you running when your system crashed?
