Finder taking large percent of cpu

My 2012 MacBook Pro fan was running for hours. I checked activity levels of the CPU and found the finder to be the culprit. I closed the window and the fan stopped running wild in a few minutes. I turn the finder back on and the fan is now starting to run wild again.
Checked the disk, no issues.
Does anyone have any other thoughts?

this file [Right Click] and Properties. on the compatibility tab(click change setting for all users);;;
then check run this program in compatibility mode for: and select windows 7.
also check run this program as an administrator. click apply then ok
if already running syncserver, disnoted kill it. using windows task manager.
This seemed to fix the problem for me....Good luck to you!

MDNSResponder taking 100 percent CPU after upgrading to 10.5.1

Hello,
just want to know if anybody else has the same problem.
After upgrading to 10.5.1 the process mDNSResponder took up almost 100 percent of CPU power.
In the system.log following line appears (very often):
mDNSResponder[171]: KQ SSLHandshake failed: -9806
I took a look at my Linux firewall in front of my network and it drops a lot of packages:
REJECT:IN=eth0 OUT=ppp0 SRC=192.168.2.20 DST=17.250.248.161 LEN=64 TOS=0x00 PREC=0x00 TTL=63 ID=47178 DF PROTO=TCP SPT=63684 DPT=5354 WINDOW=65535 RES=0x00 SYN URGP=0
Looking who is 17.250.248.161 turn out:
bash-3.2# dig -x 17.250.248.161

Maybe this is a server something to do with .MAC (I'm a member and some sync are turned on)?
I opened the 5354 port and mDNSReponder is now running normal.
But hey Apple, I don't want computers be registered by Bonjour or something else at your servers.
Can you please check this out?
Thanks for your answers.

Hi
I think I found the cause to my problem and also solved it?
When I investigated my "Console Log" the next message was repeated :
... mDNSResponder[202] Failed to obtain NAT port mapping from router 10.0.1.1 external address xxx.xxx.xxx.xxx internal port 9999
This gave me an idea and pointed in the NAT configurations.
What have I done (which solved my problem) :
• opened "Airport Utility"
• selected my Airport Base Station
• choose "manual Setup"
• choose "internet connection"
• after that i selected the tab "NAT"
• where I deactivated "Enable NAT port mapping protocol"
• and then I updated my Airport Base station
=> since then, no more the problem and de message disappeared from the "Console Log"
Greetings

Running 100 percent of cpu

My Itunes is taking 100 percent of the CPU. Any help ?

I am having the same problem as well! I have just got m y iPad 2 and rushed to get it updated and was forced to update my iTunes to 10.5.0.142 and since then I have not been able to do anything!
I have noticed that iTunes takes about 50% of my CPU, AppleMobileDeviceService takes the other 50% and the AppleBackupService gets a huge ZERO% which is great if you don't want to actually do any backups - but then again it won't let you update without doing a backup.
I have tried the uninstall and reinstall routine, done the tweaking to make iTunes as lean as possible but nothing helps. I am not at a point that I wish I had not spent what I have on apples new money spinner - I could have used it on something that works!
Going by the complete lack of response from Apple on these forums, it is clear that they don't even monitor them at all and don't care about their users at all and it's just their bank balance they are interested in.

Fontd using 97 to 98 percent of CPU

Suddenly fontd is consuming 97 to 98 percent of CPU and therefore other applications are not responding. I was not aware of any changes to the fonts on my system, there are 247. I have checked for duplicates, none, and restored Standard Fonts still no change that 247 fonts.

I am having same problem. Many say reload iTunes in a particular way. Some say that works, others say it doesn't. You can run "netsh winsock reset" and it will temporarily free up the memory once you reboot, but it impacted my IE from finding the server. Still looking. Apple must know this is a problem. As one use said, have they heard of regression testing?

Firefox is using large amounts of CPU time and disk access, and I need to know how to shut down most of this so I can actually use the browser.

Firefox is a very busy piece of software. It's using large amounts of CPU time and disk access. It puts my usage at low priority, so I have to wait for some time to be able to use my pointer or keyboard. I don't know what it uses all that CPU and disk access time for, but it's of no use to me. It often takes off with massive use of resources when I'm not doing anything, and I may not have use of my pointer for several minutes. How can I shut down most of this so I can use the browser to get my work done. I just want to use the web site access part of the software, and drop all the extra. I don't want Firefox to be able to recover after a crash. I just want to browse with a minimum of interference from Firefox. I would think that this is the most commonly asked question.

Firefox consumes a lot of CPU resources

Check and tell if its working.

New take on the old "Finder using a lot of CPU"

Been searching a lot and found next to nothing but "reinstall OS X" advice around.
My situation:
I run a 1 CPU, 4 core 2008 Mac Pro with all updates.
My Finder constantly uses 65 - 80 % CPU on one of the cores. It also has 16 - 18 threads open. It does not matter how many (or few) windows or applications I open. It will do this constantly.
I have done a little nosing about but found very little. The weird thing is that if i rightclick on the desktop, the CPU will immediately drop to normal usage.
What on earth is going on here?!?
-KJ

And out of the blue, my problem returns. Exactly the same symptoms as last time, save for the CPU usage now being 40 - 60 % of one core.
Right clicking the desktop drops the usage down to normal levels in a split second.
I tried killing the process now, and it seems to have worked, but there has to be a better way... Did not remember the advice about safe mode before I killed it, but my guess is that doing that will be like killing the process and probably would fix it for some time.
When I sample the process, I find the statistics:
Sort by top of stack, same collapsed (when >= 5):
_semwaitsignal 7945
semaphoretimedwait_signaltrap 4765
machmsgtrap 3871
kevent 1589

0x51e53 6
0xe365e 6
0x51e35 5
0x51e48 5
Sample analysis of process 370 written to file /dev/stdout
There has to be a logical explanation for this.
I have upgraded to 10.5.7 since the last time I saw this problem.

Plugin container is eating 90 percent of cpu

plugin-container is eating 90 percent of cpu when we usually look videos in youtube. Earlier this was not happening. It started in last two days. Kindly request you to solve this problem
== This happened ==
Not sure how often
== running flash movies

My computer nearly stops since updating Firefox (and gaining this Plugin-container.exe abomination). Come on Firefox, I have changed from IE because it is rubbish don't make me think the same about you.

Why execution of jar is taking larger time

Hi,
     I have the signed applet code in JDK1.1, and for the same code base size of jar file is larger then cab file, this is because of insertion of Manifest files in the jar.
     Now I am executing the same code using both JRE(jar file) and MVM(cab file). But I am observing time difference between the two executions.
     Using JRE 1.5.0_07, times comes out to be approximately 2 times of the time taken by execution using MVM.
     Can anyone tell me the reason , why execution of jar is taking larger time then that of cab.
     Thanks in advance.

Finder taking up CPU after system restore!

I recently had to restore my computer from a previous image in time machine...
Now, I am finding that the CPU is working over time and the laptop is hot. When I check in Activity Monitor it says Finder is using 103.1 of the CPU! It seems to be when I have Word open etc. Word in Activity is not using much CPU at all, but Finder's use is high. When I close Word or Powerpoint etc, suddenly Finder's CPU usage drops to 3 or something similar.
What's going on? I've restarted, and relaunched finder etc... nothing seems to stop it when a program is open.

Finder and loginwindow use 100% cpu with 10.6.8

I recently installed the patch to OS X 10.6.8 and now the finder is very unstable and uses 100% cpu and the loginwindow uses 100% cpu also. Yes I have Parallels 6 on this machine but I already "un-checked" the "show windows applications in doc" option which is the recommended solution. However, this did not fix the problem. I do not know how to determine what actual process is causing this finder / loginwindow issue. I very much appreciate if anyone has suggestion how to fix this problem.
This is on a mid-2011 MacBookPro.
thank you.

TBauer, I had the same problem with 10.6.8 using 100% of the CPU with Parallels 6 installed. The following steps solved this problem for me:
0. Take a screen shot of your Dock if you wish to remember it as currently set
1. Launch Activity Monitor and click on the CPU column so you can see Dock using the CPU
2. Move ///Users/ ... /Library/Preferences/com.apple.dock.plist to the trash
3. Click on Dock and click on Quit Process to stop the Dock
OS X will then rebuild the default Dock
4. Put the items back in the Dock that you want
That solved the problem for me yesterday morning. I've launched Parallels 6 several times now and moved the machine from my work network to home and the 100% CPU problem hasn't returned.
Hope that works for you, too!
I don't think using the combo updater will solve the problem. The problem appears to be a .plist that is generated with OS X 10.6.7 and earlier that contains icons of a larger than Apple documented size causes the CPU looping. Rebuilding the dock.plist under OS X 10.6.8 appears to solve the problem.
Parallels has issued a knowledge bulletin saying they are looking into the problem. On their web site they have another approach involving moving the offending icon out of the dock to solve the problem. I like my solution better but theirs works, too.

Finder using a lot of CPU?

Why would the Finder be using 80-100% of the CPU when I'm doing things in Safari? i'm considering taking my mac into apple to get diagnosed, but I'm wondering what would cause this to happen...

..Step by Step to fix your Mac
They will just say it's a software problem you need to fix most likely.
However if you have exhausted your software fixes and/or Hardware Test gives something, it could be a hardware problem, but likely it's software for what your mentioning.

Program taking up all of CPU Speed

Hello,
I have been lucky not to have to use the forum, until now. I recently installed a program called Garage Sale. I decided not to use it and deleted it (drug it over to trash from the finder window). Well,(now at least a week later) I turned on my computer this morning and it was running really really slow. I was finally able to get into the activity monitor and was able to find the problem. A piece of Garage Sale was still running (Garagesalehelper) and it was taking up to 65 - 80% of my CPU Speed. How to do I get rid of this thing? Thanks for any and all help.
Imac G5 Isight 512MB 180GB HD 10.4.9 Mac OS X (10.4.9)

Welcome to Apple Discussions, JoeCat24
To stop the offending process immediately, you can highlight "Garagesalehelper" in the main Activity Monitor window and then click the red "Stop Process" button. However, this fix is only effective until you restart your Mac or the application.
To get permanent relief, you must properly uninstall Garage Sale.. I do not use Garage Sale, so I cannot give you specific, step-by-step instructions. You will need to find the proper uninstall instructions. Some applications come with an uninstaller. Others list all the files that must be removed along with their locations
If you still have the Garage Sale installer or Readme files, check there to see how to properly uninstall. If you do not have this information, you may need to download the installer again to see if uninstall instructions are available there. Sometimes it is simpler to reinstall the application and then use the Help files to find out how to properly uninstall.
If none of those things work, I suggest that you contact the software developer and ask him for instructions on how to uninstall his app.
If this GarageSale is the app causing your problems, the developer offers email support via his "Contact & Support" link.

How can I find out if the current CPU is 32-bit or 64-bit?

I am developing a program that calls an external c++ executable with a certain parameter. With certain parameters, the executable often takes up large amounts of memory (<4GB). This is bad as I am often running this program on a 32-bit machine.
I am compiling this program on a 32-bit machine and running it (sometimes) on a 64-bit machine.
I need a way to find out if I have a 32 or 64 bit CPU. I can't solve the problem of it crashing with these parameters, however I can avoid calling the executable for these specific parameters when I am on a 32 bit machine.
As far as I know, System.getProperty("sun.arch.data.model") will return the size of your java Virtual Machine, but I need to know the size of the CPU
So basically, to sum it up:
I need a way of finding out what the size of the runtime machine is. (32-bit or 64-bit)
Thank you in advance!

DCexport.exe process taking a lot of cpu's power

Hi everyone!
Does anyone know where DCexport.exe comes from? I believe its used by dynamic converter is this right?
we use dynamic converter to get the html conversion from word documents to present the results on our intranet solution.
have anyone experienced problems whit DCexport taking up a lot of cpu power?

Hi,
I came across tip for speeding up OpenLdap a while ago, I have never tested it as I have never found the need to but here it is :-
Stop the OpenLdap service
Open slapd.conf which is under SharedServices\openLDAP\
Locate
*# Indices to maintain*
index objectClass eq
index cn,ou,cssIdentity,member,cssRoleDN,cssProductCode,cssVersion eq
index cssDisplayNameDefault eq,sub
and add
index uniqueMember eq
Save/Close
run slapindex.exe -f c:\<location to slapd.conf>\slapd.conf
Start up OpenLdap service again.
Though this doesn't explain the reason why you are suddenly getting performance issues, do you have a large amount of native users/groups ?
If you are on 9.3.1 have you tried Sync Native Directory from Shared Services.
Cheers
