How to lower the CPU usage level?

u09mi7

You can launch activity monitor to see what processes are using what amount of CPU. Also there is an application called AppTamer it is a sharware program and has gotten good reviews. It helps to reduce CPU usage on programs that are kind of in the background, one's you're not using at the moment. I would also recommend iStats Menu which monitors are the vital systems, memory, cpu, temps, disk activity etc...if you don't want to pay for the license the dashboard widget iStats Pro is free of charge and does the same thing. Do you have a lot of apps starting as login items? Hope this helps. Follow up and let us know how things are working.

mds maybe ? (spotlight and its cpu usage sometimes get crazy)

I'm looking at activity monitor now, mds seems to only be using about 1.4% CPU and 47.7MB of RAM. I don't see Spotlight using any CPU. SytemUIServer is only using about 4%. My system with just Chrome open, two tabs, iStats Menu running, and Sophos Anti-virus running in the background is at about 96% idle.

Oh, don't get me wrong, on "normal" time, mds and mdsworker (which are the spotlight indexing engine) are just fine, but there are some specific cases when it cause some problem. Still, we'll only be able to track what the problem could eventually be as we'll have a more detailed view on his specific cpu usage.

by example, right now i have about 90% idle with mail open, iTunes (not playing but open), twitter, chrome with 3 tabs open (but no flash playing), and some other background stuff.

Hi, you can lower the CPU usages by uninstalling unwanted softwares, delete files, folders, and other items on your disk that you no longer need and Clean trash. I assure this will increase your Mac Book performance.

Sorry to hear AppTamer did not do much for you. What do you have as login items? You can check by going to sys prefs,accounts,login items. try removing them one by one to see if there is a culprit there. Could be possible sth. there is eating the CPU. What programs are you normally running during a session?

I know for myself I have a few apps that run in the background but do ont eat much CPU. Look at your login items. Let us know how you did with the CPU issue.

"is there anything else i can do?"

Uninstall the anti-virus software. Most commercial AV packages for Mac do more harm than good and are not needed it you are apply reasonable prudence in your browsing habits..

Note that Spotlight does not show up in Activity Monitor under that name. The background processes that support it all start with "md," like "mds," and "mdworker."

Do you have Activity Monitor set to show "All Processes/" If not, you may not be gettiung a true picture of whats active in the background. AM defaults to "My Processes" and the typical CPU hogs tend to be owned by the system not teh user.

Uninstalling software and discarding unwanted fles will free up storage space, but it will do nothing at all to unburden a heavily-loaded CPU — unless some of the software being discarded was actually running and hogging the CPU. So don't bother trashing files and software until you've followed Allan's suggestion above and used Activity Monitor's "All Processes" listing to find out exactly what really is hogging the CPU.

One common culprit is a hung-up printer queue. With your printer turned off, select "Print" from the file menu in your web browser as if you were planning to print this web page. When the printer's icon appears in the Dock, click once on it to open the print queue window. Select each item that is queued for printing and click the Delete button at top left in the window. After deleting all items, close the window and check your CPU usage again in Activity Monitor.

is there been any alternate method that i can reduce my cpu usage and can remove error 0x80090318 except autoruns and cmd method bcz i have tried both but neither resolved my problem
