Kappy in Safe Mode now. It still seems slow. Although the CPU is not showing Kernel tasks so I cannot get a read on whether that is high.
It just took 30 seconds to open Safari and this text I just wrote showed up in a delayed way...after I wrote it. Everything seems delayed.
Fans are reved up and the computer is hot.....
What do you see in Activity Monitor:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Another thing you can try is to create a new admin user account. Log out of your account and into the new account. Does this help any?
Some part of your hardware is either sending bad temperature data or your computer is so full of dust that its actually having to use Kernel task as a cooling solution.. (ouch..)
Either way I can say with confidence that problem is hardware related, not software..
Step 1, Clean out the fans and heat-sinks,
IF: not fixed-
Find a temperature monitoring application that can show all the realtime censer data in the laptop.. (Like Istat menus) This should be obvious what’s broken (the censer should be stuck on a high reading)..
THE FIX: Replace the hardware thats broken (In my case a battery sensor).. Warranty it or buy the part on Amazon..
IF: Your unable to replace hardware because of out of warranty, or not enough money, (my case, just lazy)
Step 3, (quick and dirty as they say)
Remove the Model Identifier PLIST file for your model mac.. (my case MacBookPro8_2.plist)
read how to at:
Whats this do?
Well I’ll tell you, The kernel_task0 has a base configuration that can manage all Apple hardware.. This is the state that your kernel boots in when you push the power button, eventually this task is given to a higher level operating system task called kernel_task0. But when kernel_task0 is given this it checks a Model Identifier file(yourmac.Plist) to get statistics about what it should expect that models censer data to look like and the Ratio it should use fans over cpu choking… Without that file the system defaults to a linear system method (if Avg. temperature goes up, then turn fan-speed up).. which is what the bootcamp windows side uses also.
All of these temperature controllars have many redundant hardware safegardes. so you really can’t do wrong with this method..
And your computer will feel like new, out of the box again.. mine did..
Best of luck!
On with Apple Support this morning. He had me unplug the LCD monitor I had connected to my MBP. Viola! Kernel_Task went from 650% to 1%
He said that LCD monitors can make the computer pull a lot of power.
Time to look for a good 24" LED. Any suggestions?
PS... thanks for all of your support here and trying to help me...
I have played with the monoprice monitors and have been very satisfyed:
Question: Did you have any problems with Wifi when your monitor was plugged in to your laptop? I've had this strange issues with the apple cinema displays shorting out the Wifi on MacBook Air's.
No WiFi probs at all.
Drag, I have a 20" Apple monitor, but it is 8 years old and LCD as well :/
I have been looking at ViewSonics
I will look at yours, but any thoughts on these anyone?
The VX2770SMH-LED 27-Inch IPS LED is the better of the Two… BUT that being said both these low resolution “monitors/Tvs” are in my opinion mediocre at best. I’m not a fan of ViewSonic either, most of there products I’ve tested feel like there designers only half cooked them..
Anything under 2560x1440 is just not worth the money anymore. Korean off brand Monitors with the same LG IPS panel that apple puts in the 27” iMac are the latest biggest trend.
When I buy a display here are my key point’s:
1- Under $400,
2- Always IPS, (or newer/latest technology)
3- Must be greater then or equal to 2560x1440, (or newer/latest technology)
4- After all of the above are met base my purchase on reviews…
The irony is that the only monitor that didn’t follow these rules was my apple 23” Cinema display (was not Under $400). It was the first to start acting up and died only after a couple years.. My cheaper 30”, off brand, 2560 × 1600.. Out lived it by a long shot. So Brand does not matter if you find a quality product!
Hope this helps..
Ok, here's something odd. I looked around the web a bit more regarding my problem and someone said if you close the lid on the MBP things calm down...well, they did. I can run cool, with no Kernel_Task insanity with the lid closed. Drag is, I sometimes run 2 monitors if I am using PS or Dreamweaver and Skype is a problem since the camera is in the lid and if i open the lid, well you know the rest lol...
No bootcamp here.
I just do not get why this monitor would have worked fine for so long and then all of the sudden made it hard for my MBP???
Also, why is an LED better? Less system power needed to run it?
Again, I can run the LCD for some hours, but then at one point it skyrockets the Kernel_task back up to 600% :/
