Mountain Lion freezing

I'm so sick of this sh*t.

The computer didn't freeze now but the kernel_task process went up to 100%. WHY is it so hard to have a system that works fine?

I can't reboot/shutdown the computer when the kernel_task-thingy starts acting up. I want to do that because there is no other alternative to stop it. It seems that the computer is waiting for something to end. All I can see is a gray screen with a circle that moves around.

When I'm sick of waiting I push the power-button and turn the computer on. After that the ML default desktop-wallpaper is showed.

The kernel_task at 100% CPU and the freezing problem is two really annoying problems with my beloved computer.

I'm starting to think that I must to a fresh re-install of ML and don't upgrade to 10.8.2 until it is fix

😟 😟

Sorry to post this issue in this thread.. They're not related I think but it is so frustrating.

Wow, the computer froze up now like 10 seconds ago. It happened when I had Spotify and Safari open.

WHAT IS HAPPENING? I'm going to do a fresh install now and stay on 10.8.

If you guys want to know my plan, it is to buy an external hard drive, make a back up of my pictures, documents, and some applications, and then erase my hard drive and do a clean install of Mountain Lion. Then restore my pictures, documents, and some applications back onto my Mac.

That is my plan also! But I remembered that my internet-connection is so slow lol, so it would have taken up to 6 hours to restore the computer. I'm going to wait a while until I get a better connection, which is maybe around Christmas-time 😉

Yeah my internet connection is blazing fast 🙂. What do you mean by restoring though?

Nice.. Mine will be it eventually. By restoring I mean, go to Restarting-bottom and push the Cmd + R-button. Then you will come to a page where it says Restore from a time machine-backup or Do a fresh reinstall. I'm doing a fresh reinstall when my internet-connection is better. I can't believe the computer doesn't say anything about the freezing part.

Yeah but I'm deleting my hard drive first. Then I'm gonna reinstall OS X. Then, I'm going to restore from Time Machine Backup within my new OS X install, not Recovery. What were you planning on doing?

Yeah, ok. I'm doing a recovery. But it says Fresh install, but maybe that is a recovery. I already have a backup 🙂

Oh well if you were going to do what I want to do, you would first go to Disk Utility and erase the hard drive. Then go to Reinstall OS X. Then once that finishes restore the backup. But not from the the Recovery screen(unless you want to).

Is it better to that? Erase it and do a backup? I had a Lion-backup before and I could not use it because my Retina display-Mac had a different build number.

Maybe its better to do as you are planning to. Erase it and then do a backup. It should work with ML now. No fuzz about the build number etc.

We'll yeah but I'm not going to restore EVERYTHING back onto my Mac when I'm done reinstalling OS X. Also why is there an option to "Restore from Time Machine Backup" in the Recovery mode? I mean why couldn't you restore from it on your regular OS X partition by opening up Time Machine?

Yeah, ok 🙂 I guess you could restore it directly from the regular OS X partition. Maybe they want you to have two choices, I don't know.

I'm going to hold off a bit now and wait. But it seems ridiculous to reboot/shutdown my Mac every other day because of these to things.. I mean.. come on.

I ran the Onyx tool automation with all the tabs selected and my Mountain Lion has not freezed in two days. Worth a try: http://www.macupdate.com/app/mac/11582/onyx

I will report if the freezing starts again.

Nice to hear steelduck!

I did the Onyx-procedure myself now. The same automation with all the tabs selected. Then a reboot.

Hopefully that did the trick but you never know.. Thank you for your great tip.
I will also report back if there is any issue.

Hi there, just wondering if you gave the Macbook Pro EFI Firmware update 2.9 a whirl? (Sorry if I missed that in an earlier post). The issue it resolves; "This update resolves an issue which can cause the system to hang during heavy processor loads " sounds exactly like what is happenning to my mid 2011 Macbook Pro with SSD since ML 10.2.8 update but firmware does not work with my model! Just randomly my software freezes when doing some processing such as pixel editing in photoshop, raw conversions in DXO Optics Pro, or even when doing a 1.12 Gig Garage Band update through the app store. First the software seems to freeze, force quit also not accessible, then as I move the curser to other programs or finder the whole machine freezes and I have to physically shut it down with power switch and reboot every time. Sometimes happens every couple of minutes... Tried Onyx as well, MBP seems a bit better but crashed again today trying to burn a CD direct from GarageBand...so issue still there. Never had a problem before 10.8.2, seriously effecting productivity for work... BTW, does anyone know if a machine crashes after it has downloaded 1.12 Gigs of loops from app store but fails to intall them whether they are taking up space on hard drive somewhere..? I tried the update twice and it crashed staight after download each time... I hope there is another firmware upgrade for older Macs or that 10.8.3 is not far away and has a sure fix for this really annoying problem...
