Mac OS 10.5.7 high user account CPU usage

Every few days, my MacBook Pro, 2.16, 2 GB Ram, will run very hot at 70 degrees Celsius. Activity Monitor show high user CPU usage, usually at about 52%. I quit all non-essential services without being able to reduce user CPU usage at all. A reboot always brings usage down to normal, as well as the temperature. For the life of me, I can't figure this out. This has been going on for over a year, and none of the OS updates have changed the situation. Any ideas? What am I missing?

    Thank you, but the issue is not air flow. It is high CPU usage creating the hot temps. BTW- I use SMC Fan Controller

Hi.Maybe you don't let your notebook get the air that must take.Probably if you have it on your feet on bed the macbook cannot breathe.Check this software out if you need further information about your computer's hardware temperature.

Why Mac OS X Mavericks is so much terrible in memory management? Can anyone tell me how to optimize it?


Hi John,
Millions of users are using Mavericks edition of Mac OS X. That's perfect for most, but some users claim slower Mavericks performance.
If you are also some of them, then here are some of the helpful tips which improve the system performance.

1. Update Apps: After installing Mavericks, run the software updates. You should do this to ensure that all the Apple software is running as per the latest version.

2. Check your Apps: Not all the available application in the system comes from the Apple App store. It is also possible some 3rd party apps eating system resources and as a result, it degrades the performance of Mac Mavericks.

3. Check Activity monitor and console: If things still run slow, then launch Activity monitor and Console.
Activity Monitor will show all the apps which consume more CPU resources and you can take appropriate step against those resource consuming apps.

Even, after trying these above written steps, the performance of Mavericks doesn't improve, then use software. You can give a try to Stellar Speed Up Mac or any other.

My 2001 MacBook Pro fans run almost constantly, while my previous 2009 MacBook Pro fans seldom ran. Why is that?


I had to chuckle, because many MBP users actively seek out applications to make the fans run more often and more vigorously. It seems that early models of MBP would quietly cook themselves to an early demise.



You should follow Ted James\' advice regardless - it\'s easy to do and worth doing whether that\'s your problem or not. However, I had a similar problem with my MBP and found that it was a browser plug-in that was the CPU and running the system hot. If it\'s a software package making your mac run hot, that\'s a little more tedious to troubleshoot, but still pretty simple. First - try this simple step: While your mac is running the fans (misbehaving) start the Activity Monitor app - which is in your Utilities folder. If you prefer to use LauchPad to start applications, then you may need to look for "other" start typing "activity" in the search box, b/c the utilities are not shown by that name in some newer OS X releases. Once Activity monitor is running, select the CPU "tab" at the top or bottom of the app. Now you should be able to see how busy your system is in a moving graphic at the bottom center of the app. If your CPU is running at nearly full capacity, have a look at the column called % CPU. If the process name a the top of the list is contributing the majority of your % CPU, then that is the candidate for an errant application overheating your Mac. I\'ve attached a screen shot of Activity Monitor working on a quite system with almost no activity.



2001-macbook-pro-fans-run-almost-nmanvh0t0unvrj5oupx45jw5-5-1.png



It should be obvious, but the next thing to try is to exit or kill that application and see if that allows the fans to spin down.



Hope that helps.

I am running OS X 10.4.11 and would like to upgrade my operating system?


Please provide more information.
To what would you like to upgrade it?

Since OSX Mavericks was just announced, I'm going to assume that's what you're wanting to upgrade to.

Not all Macs can run Mavericks.

Mavericks Capable Macs

Mavericks, like its predecessor Mountain Lion, requires one of the following Macs with at least 2 GB of RAM and 8 GB of available hard drive space:
  • iMac (Mid 2007 or newer)
  • MacBook (Late 2008 Aluminum, or Early 2009 or newer)
  • MacBook Air (Late 2008 or newer)
  • MacBook Pro (Mid/Late 2007 or newer)
  • Mac mini (Early 2009 or newer)
  • Mac Pro (Early 2008 or newer)
  • Xserve (Early 2009)

If your Mac isn't one of the ones listed above, you won't be able to upgrade.

If you have an iMac, MacBook, MacBook Pro, or Mac mini model that was originally released in Early/Mid 2006, the latest version of Mac OS X your system supports is Snow Leopard.

Fan won't stop


Resetting the PRAM may do the trick:
You reset the PRAM by rebooting a Mac and then immediately hold down the Command+Option+P+R keys, you will then hear the Mac reboot sound again, signifying your PRAM has been reset. You must hit the key combination before the grey screen appears otherwise it won't work.

you've tried rebooting, you've reset the PRAM, you've done it all, but your Mac is still behaving strangely. What next? In certain circumstances, resetting your Mac's System Management Controller (SMC) can be a solution. This is sometimes necessary to restore normal lower level system functionality to your Mac.

Here's how to reset the SMC on any type of Mac (and any version of OS X) and the type of problems that it may resolve.
When & Why Reset SMC on a Mac? Some Common Hardware Reasons

Typically it's power and hardware related issues that can be helped or resolved by resetting a Mac SMC, particularly if you're having these types of problems:

* Issues with your Mac's cooling fans and fan management: fans run constantly at high speed, fans run high despite low CPU usage and adequate ventilation, fans not working at all, etc

* Power management and battery problems: Mac isn't turning on, sleep isn't working, random shutdowns and reboots, battery isn't charging, Mac won't wake from sleep etc

* Light problems and improper lighting management: battery indicator lights aren't working, display backlighting isn't adjusting to ambient light changes, keyboard backlights not working, etc

* Video and external displays not working: display brightness functionality not working properly, target video mode isn't working properly, external display isn't working, etc

* General performance and functionality problems: abnormally sluggish behavior despite no CPU or disk usage, external ports not working, airport & bluetooth aren't showing up, external devices are not being found, etc

So now that you've concluded you need to reset your SMC (Note that the SMC is on Intel Mac's only), here's how to do it on MacBook's, MacBook Pro's, iMac's, Mac Mini's, and Mac Pro's. Notice that the reset instructions are different for MacBook and MacBook Pro's if you have an internal or detachable battery.
Reset SMC of a MacBook Air, MacBook Pro Retina, or MacBook Pro's with an internal non-removable battery

This is how to reset SMC on most modern Mac laptops:

Shutdown your MacBook Air / MacBook Pro
Connect the power adapter to your Mac
On the MacBook/Pro's keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
Release all keys and the power button at the same time
Boot your Mac as usual

Here's the key sequence to hold down:

Reset the SMC of a MacBook Air or Retina MacBook Pro

Do keep in mind that by resetting the SMC you will lose power specific settings, like the time it takes to sleep a Mac and other customizations to power settings. No big deal, but if you have made many changes to your hardware behavior you will want to adjust stuff like sleep behavior again.
Reset SMC of an iMac, Mac Pro, Mac Mini

Resetting SMC is different for non-portable Macs:

Shut down your Mac
Disconnect the power cord
Press and hold the Mac's power button for 5 seconds
Release the button
Reattach the power cables and boot the Mac as usual

Reset the SMC of a MacBook or MacBook Pro's with detachable batteries

mac reset the smc Older MacBook laptops with a removable battery can reset SMC with the following approach:

Shutdown the MacBook/Pro and remove the battery
Disconnect the power adapter, hold the Power Key for 10 seconds
Release the power key and reconnect your battery and power adapter
Turn your Mac on
Let boot as usual

Hopefully that will clear up your problems, if not it might be worth a visit to the Apple Store or a certified repair center.

Happy New Year,
Kerry

Mac book air - spinning wheel shows up- slow spped.


install Istat (google it, get the one that's for the menu) to monitor your cpu temps and fan speeds...when you notice they start maxing out, open up activity monitor and see what is eating up your CPU....you must have something in the background running that is causing the CPU to max out...if that's not the case then you might have a defective logic board. ------- check for start up items. thn check with activity monitor CPU and RAM usage, if its okay then check your hard drive with 3rd party programs to see if its failing. ----- Have you tried resetting some of the low level hardware?

System Management Controller (SMC):

PRAM and NVRAM:
http://support.apple.com/kb/HT1379

Other thing to look for might be temperature (install iStat Menu and/or iStat Pro) from iSlayer.com. -----

How do I find out what my CPU usage is on my MAC laptop


hi dv4242

Here is how to do it :
  1. First open the Activity Monitor
  2. Right Click (or click and hold, or CTRL click) on the Activity Monitor icon in the dock and select ‘Keep in Dock’ (if it’s not already there)
  3. Right click on the Activity Monitor icon again and select the ‘dock icons’ menu
  4. From the ‘dock icons’ menu select the ‘Show CPU Usage’ item
  5. There you have it, a nice little visual representation of your CPU usage, it is even separated by cores (if applicable)
Hope that helps

Mac book Pro high CPU usage with nothing running


I would worry the fan is not fulty, you may want to get apple to check the pc for you but they normaly charge a diagnostic fee.
The other possibility is your sitting it to close to a wall or your sitting it on the transformer (though i doubt it)
The incriment in system resorces would be in responce to the build up in heat but i expect thats only a short lived spike.
make sure you have it in a clean well vaccumed area away from carpet or other dust collecting surfaces.
if thats unavoidable then stick a vaccume to the air vents to clean any buildup you would be surprised what i have seen in dust buld up in fans after 4 months running a laptop on car seats uni benches & other less clean surfaces.

My Macbook fan keeps running


There may be high CPU usage by some program. It would be normal for the fan to run if the CPU usage is high. Check the Activity Monitor (found in utilities) to see if something odd is going on.

I had a problem where iPhoto quit working, and somehow was using 90%+ of the CPU. I could view the photos, but some operations did not work and the only way to exit was Force Quit. I had to remove and reload iPhoto.

My MacBook Pro MB766LL/A


First of all, do a "Software Update". There may be a firmware update for the laptop since it was manufactured.
Also the macbook pro does run hot, especially if you are doing anything cpu extensive. You could launch Activity Monitor and see if some process is hogging the cpu.
I have an antec cooling pad under my macbook pro. This helps a lot.

THis is normal. It is based on the amount of CPU being used. If you are running a lot of apps or CPU intensive apps then it will run hot. If you use Cmd-space and type 'activity' you will select Activity Monitor from the list. In there you can see what is using the most CPU. (get back to me if you need more info on using this app). Playing videos uses quite a lot of cpu for decompression. Playing music doesnt. Check also howmany widgets you have open by pressing F12. Close them down by holding the alt key and clicking the x in the top left corner of each.

This should help you reduce the heat a bit. Also think of getting somthing like the iLap. I use this myself (using it right now infact) and it's pretty good.

All the best
