Searching Google, it seems kerneltask is OS X's version of Windows's 'svchost.exe' - the notorious do-everything process that you can't ever truly debug, you have to just manually flip switches until one of them works. Is there any way I can more easily get to the bottom of the out-of-control kerneltask activity?
Out Of Control (greydavenport) Mac Os Catalina
Preamble: I was an active member at one time, but it's been several years, and I can't remember my username, so new one here. Apologies for not being a forum denizen and just creating an account to post this issue.
I have a Macbook Aluminum from 2008, installed OSX 10.6.3 disc last year when everyone stopped supporting 10.5. Over about the last month, it's been running significantly more slowly. Yesterday, the screen simply froze and wouldn't respond to CMD+OPTION+ESC or any input, including power button. I unplugged it and let the battery run down to zero. When I reconnected the power and started it up again, it wouldn't boot properly. It hangs at a blank gray screen for a very long time, then goes to the Apple logo/spinning 'gear' screen, where it stays indefinitely (I left it up for a few hours yesterday).
I've tried as many of the steps from Mac's support site (http://support.apple.com/kb/TS2570) as I can. It seems to have let me clear the NVRAM/PRAM, but it doesn't seem to take any other keyboard input -- it won't, for example, do a Safe Boot, no matter how long I hold the Shift key, nor move to any screen except (when it eventually loads) the Apple logo. I CANNOT BOOT FROM THE INSTALL DISC -- if I try to start the computer with the disc in the drive, it just makes a kind of periodic pulsing noise for a while, then ejects the disc.
Is this a failing/failed hard drive issue? (And, if so, can I recover any of my data?) I've never changed the hardware on this comp except for a battery replacement last year. Does anyone have any suggestions? I don't have a warranty or support plan anymore, so I'd like to try to resolve this myself if at all possible.
Additional info:
I backed up to an external HDD with Time Machine no more than a few days ago, but I'd like to retrieve the data written since then if at all possible.
Possibly unrelated, but my DVD drive's had problems. The sound of it loading and spinning a disc has gotten a lot louder -- almost sounds like crunching -- and makes loud buzzing noise when the disc ejects. A few months ago it actually cracked a DVD in half and ejected the pieces, so I've (understandably) refrained from using it.
Though Macs are compatible with AD environments, they aren't really inter-operational. From my experience with using Macs in such an environment is letting the user(s) know this fact. I could be wrong, but I was never able to find a 'fix' for these same issues you are seeing. I only had the advice to reboot or re-seat the network cable.

I know it's not much, but hopefully it's reassuring to an extent knowing it's not just you.
(I have since left that company- but on my way out I converted all the non-believers to using Windows for work.)
