System Events startup problem

Recently I noticed my Macbooks fans where spinning all the time for no apparent reason.
Upon further investigation I found out every single time I reboot my Macbook an application titled "System Events" will use up 50-60% of my CPU (continuously) until I force quit it from within the Activity Monitor and after this it will happily idle at around 3% presumably doing what ever task it does.
I didn’t want to outright delete the application as I have no idea what it does and its also inside a folder labeled "Core Services", seemed like an area to tread carefully within.
At least I have found a relatively simple work around but I was wondering if there is anyway to stop this happening all together?
So far I've tried to disable each application that is being loaded on startup one at time to see if its any of them, Ive also tried adding and deleting the offending System Events application from the startup applications.
Ive had no luck so far so any help will be much appreciated, if you need any further information on my Macbook I will be more than happy to provide it.
Thanks for reading.
EDIT: Ive also tried leaving the Macbook running while I was at work for around 6 hours, when I came home System Events was still at 60%, the logic behind doing this was to see if it was doing some sort of task system wide and I wasn’t giving it enough time to execute.
Also these are the current applications running on startup.

Welcome to the forums!
"System Events" is widely used by AppleScript and by apps using AppleScript. Do NOT touch the app itself. You can certainly remove it from Login Items without making a scrap of difference - it will simply take a fraction of a second longer for the calling app to use it.
IMO, you are going about things the right way. I am, in fact, surprised that one of those items you list is not the culprit. The culprit is most likely to be something in your Login Items or in /Library/StartupItems. You can ascertain which by logging into another, clean, account - create a temporary one if you don't have one. That will immediately tell you if the problem is limited to your account or is global.
Tell us whether the problem is global or not, and that there is no doubt that you have exonerated the above items, and one of us will tell you where to look next.

Windows 8 system doesn't get internet, says system event log on service has some problem of STOP 0xC000021A error which system restarts very slowly

Hi, my system runs on windows 8 on hp laptop envy series. All of a sudden, system event log on service stopped, errors which prevented the system to log on services. It displayed error of STOP 0xC000021A when i use system restore to roll back to previous
configuration. Also when I tried to refresh my pc, it says i can't do changes as log in was switched to prevent the changes by notification.I don't know what to do next, I tried to put recovery dvds which I made when system was bought, now not at all working.
Internet is not active, not able to resolve by trouble shooting and system taking lot of time to get dsktop. Previously I used to get my desktop in 10 seconds. Now its 10 min. May be I m infected with virus. My files, they are there. I tried to transfer some
files by pendrive to another system, now the new system(where i put my files in another system) crashed, windows 7 system which does not display desktop, icons etc and not at all workable.
Also in my hp system, i m unable to open control panel. if its opened, it will not go off, when i use task manager, it says explorer and shuts down. I had to force restart the system. Please resolve something to get my hp laptop workable. I m waiting for
my MS thesis to be working on that. My files are locked and no way to transfer, I fear of infected by virus to another computer also.
Pls give instructions to hw to set my hp laptop at the earliest without losing any of the files. Idon't want to reinstall and lose all the data for timebeing. Else, inform me the option for copying data safely. I tried to change the adv startup and recovery
by changing the boot sequence by DVD but this also shows error 0xC000021A and asks us to see the details. I didn't understand all this. Pls help asap.
Thanks

If you can boot either from the win 8 dvd or in safe mode we need the DMP files
We do need the actual DMP file as it contains the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.
WE NEED AT LEAST TWO DMP FILES TO SPOT TRENDS AND CONFIRM THE DIAGNOSIS.
Please follow our instructions for finding and uploading the files we need to help you fix your computer. They can be found here
If you have any questions about the procedure please ask

System Events and Coreservicesd takes up all CPU at startup

Every time I boot up my laptop System Events and coreservicesd take up to 85% of my CPU. It takes about 10 minutes for it to finally go away and it makes my fans blare. If I'm in a public place I force quit system events which makes them both go away. What in the world causes this and how can I fix it?

I'm having this same problem. It is related to Growl, and perhaps a recent update of Growl to 1.1.3. I'm trying to figure out a way to fix this without uninstalling Growl, since I find this app very useful.

Start-Up Problem: "Where is System Events?"

My MacBook Pro recently had leopard unexpectedly quit. It happened about two days ago, and I reset the computer as the notification instructed. No problems once that was done, it was back to business as usual. However, leopard just crashed again today, and now, when I start up the computer I receive a prompt that asks "Where is System Events?" and waits for me to choose an application. The items on my desktop seem to be partially loading, with some looking fine, others seemingly unrecognized. What can I do to fix this, and how should that prompt be handled?
Thanks in advance for all your help!

Well, with a tip off from another help post, I searched around my Mac for an app of the system events name. Spotlight showed nothing, but under Mac HD > System > Library > CoreServices I found one. So, I pointed the prompt to this file, System Events.app. It did nothing immediate, but upon restarting, everything seems to be back to normal. I suppose the crash somehow disturbed the system's set path for using this file, but after my manual redirection of it, the prompt has not returned, and no further problems have occurred. Sorry to have taken up space on the board when I solved it myself. Hopefully anyone with similar problems might find this note helpful.

Startup error message:System Events got an error: NSInternalScriptError (8)

I just upgraded from Panther to Tiger on my mac Mini and I can't seem to get rid of this message everytime I boot up:
System Events got an error: NSInternalScriptError (8)
Any idea how I can "fix" this?
Much thanks.

Do you have any login items listed in the Accounts pane of your System Preferences? If so, disable them and restart to see if that clears the message. If so, then re-enable them one by one and restart to see which one it is.
In doing a Google search, that message appears to come from an AppleScript. So perhaps you have an AppleScript running at login that needs to be modified to be compatible with Tiger...

System Events keeps crashing

First of all, forgive me if there is a more appropriate category for this to be posted in. I couldn't think of anything better suited to this exact issue.
On every boot, OS X brings up a standard "Application quit unexpectedly" dialogue for System Events. I can simply close this and disregard it, and it does not affect operation in any way.
However, just recently I have found that when I attempt to launch Adium, the open-source IM client, it hangs for a good deal of time and then brings up the same dialogue. Adium, in the end, is unable to start and must be forcefully terminated.
I was wondering if there might be any relation between the two occurrences. I do not know exactly what System Events is responsible for, and if someone could enlighten me, perhaps I could go about fixing the annoyance at startup, and possibly the problem with Adium at the same time.
Thanks in advance.
Oh, another note: both problems started very recently, at least one of them around the time I updated to 10.4.11.

You can certainly remove System Events from Login Items, and I suggest you do. It serves no useful purpose by being launched independently in that way. It will be 'called' (transparently) by an AppleScript (or something similar) as and when needed. The time penalty for it not already running will be indiscernible.
However, sorry to tell you, but removing it as a login item is unlikely to make a scrap of difference to anything. Having System Events made to run in that way is unnecessary but should not be harmful in any way: it just runs consuming no CPU, only being used when 'called' by an app, and it is the app that is doing the calling that I would suspect. Did you also check /Library/StartupItems?
There is the remote (very remote) possibility that System Events.app itself is corrupted. You can easily check that. Launch Script Editor (in /Applications/AppleScript), paste this line:
tell app "System Events" to say "Hello Benjamin"
Hit <Enter>. The line should format (the text will change its appearance) without error; then hit the 'Run' button. If, as I expect, that causes no error, you are condemned to carry on playing "hunt the app".
Does the error message appear when you log into another account? (Create a temporary account if needed, and then delete it).

Windows 8.1 - Windows Couldn't connect to the System Event Notification Service service

I have an issue that has been bothering me for a while on new 8.1 computers. Standard users are not able to log into the computer on the first try consistently. They receive the error message: Group Policy client service failed the sign-in access is
denied. They are stuck at the logon screen.
If an administrator logs in (local or domain), they can log in but get a black desktop with two error messages. The first is Location is Not available - C:\Windows\system32\config\systemprofile\Desktop is unavailable. The second error message is a popup
balloon. It states "Failed to Connect to a Windows service. Windows couldn't connect to the System Event Notification Service service."
When a standard user attempts to log in, event viewer records three warnings. They are listed in order from oldest to newest
The winlogon notification subscriber <Profiles> was unavailable to handle a critical notification event. -Logged 9:14:44
The winlogon notification subscriber <GPClient> failed a critical notification event. - Logged 9:14:44
The winlogon notification subscriber <Profiles> was unavailable to handle a notification event. - Logged 9:14:49
After a reboot, users still have the issue. I noticed that the user profile services and system event notification service are not running though their startup type is automatic. They start after a minute or two.

Hi Joseph__Moody,
Based on your description ,I assume it is a domain environment .First of all ,I would suggest you to try to update all the machine .
"I have an issue that has been bothering me for a while on new 8.1 computers"
Do you mean all the Windows 8.1 machine share the same symptom or just a specific one ?Did the machine work correctly before ?When did the issue start to occur ?Have you installed any third party software before ?Can we operate the machine when we login with
an administrator account ?
If the issue occurred with the specific machine :
"The first is Location is Not available - C:\Windows\system32\config\systemprofile\Desktop is unavailable."
Please try the following suggestions if we can operate the machine when we login with the administrator account :
Open Windows Explorer and navigate to: C:\Windows\system32\config\systemprofile and verify if it has the Desktop folder there.If the folder doesn`t exit, we can copy from C:\users\Default\Desktop location(This folder is hidden by default).
We also can try the following suggestions to have a troubleshoot :
1.Run "sfc /scannow"or "dism /online /cleanup-image /restorehealth" to check the health of the system files.
2.Perform a full scan with an antivirus software.
3."They start after a minute or two."
I suspect there is a third party service confilct here. Please perform a clean boot to verify whether there is a third party conflict here .
How to perform a clean boot in Windows
https://support.microsoft.com/en-us/kb/929135
If the issue occurred with multiple machines in the domian ,I would suggest you to check whether you have configured any logon scripts and logon group policy .We can remove the machine from the domain to have a troubleshoot .
If the issue occurred recently ,we can perform a system restore to recover the machine to a previous normal point.

Dual Monitor Startup Problem on MacPro - Solved

I have a model 53135LL/A = mid 2010 MacPro with 8 cores, DUAL monitor cards and monitors, 24GB memory, running Lion 10.7.3. It is important to note that I am also using the Apple bluetooth Magic Mouse and the smaller, bluetooth keyboard (no numeric keypad). This unit was supplied with Lion in December 2011 and has had a startup problem from the beginning as follows:
1 - when starting from a cold start the dual monitor positions are reversed from the correct position
2 - additionally the USB and firewire connected devices (e.g. Wacom tablet, 2 card readers) do not function properly.
The workaround for me has been to start the system, wait for the logon screen, then click restart. Upon restart everything comes up and functions correctly.
Specifics on my setup and starting problems:
1 - My main monitor (Monitor #2) is a large gamut monitor that is located to the right. This monitor is connected to card slot 1 as that is the faster card slot (pcx16). The second monitor (Monitor #1) is an ordinary unit and connected to card slot 2 (pcx4). The monitors are set up as an extended desktop.
2. The Wacom tablet (Intuous 3 wide) is connected to USB port on rear of machine. CF card reader by Delkin is connected to Firewire on rear of machine, and an SD card reader is connected to USB on the rear of the machine.
3. My dock is positioned on the left side of the left monitor. The menu bar is along the top of the left monitor, and all desktop icons are on the left monitor. The right monitor has no items on it.
On a typical cold start, as mentioned above, the apple logo appears on the right and then the logon screen appears on the right.
If I proceed to logon at that point, all the desktop items move to the right monitor and the computer thinks the positions are reversed. In other words, it behaves as though the right monitor (#2) is on the left of the desktop and left monitor (#1) is on the right.
Additionally, the Wacom tablet using either pen or mouse does not map over the full desktop range. If I use either card reader and then eject the card, no further card insertions will be recognized.
To fix this, I simply restart the machine thru the apple menu and everything comes up correctly.
I had discovered, that instead of completing the logon on a bad cold start, I could simply restart from the logon screen and all would work correctly.
On occasion, the logon screen would come up on the left monitor (as it should do) and in that case, if I log on all works correctly.
I have worked with Apple support on the phone, clearing setup ram etc. Have had the unit in to Apple store for hardware check, all OK. Next suggestion was reload OS and start over - no thanks.
SO - Here is the latest.
If I turn off my keyboard and mouse before starting the machine, then wait for the logon screen to appear - It starts correctly, with the logon screen on the left. I can then turn on my keyboard and mouse and all works as it should.
Bottom line - there appears to be a startup issue with Bluetooth devices from a cold start. Note that once the machine has been used for a bit, I can turn it off for short periods of time (e.g. 30 minutes) and it will start correctly even with the mouse and keyboard turned on.

That's how dwm behaves. I believe dwm's multihead support is rather lackluster out of the box. You might want to check out some of the patches they have, and ask around in the dwm hackers thread.
I currently have dwm simply draw status on all monitors, but I'm investigating separate status bars per monitor. We'll see where that takes me. Dwm is a tinker's WM!

System Events not working correctly with Acrobat Professional

Hey Guys, I have a script that I have written that automatically enables security settings on a PDF through Acrobat Professional. Because of Acrobats poor scriptability I am forced into doing much though System Events.
This is not a major problem... however when activating some settings in the security settings, often warning Alert dialog boxes appear when you tell System Events to enable particular settings. These Alerts do not have a title... The only way I have been able to get the script to deal with them is with the following code:
if title of front window is "" then
    tell front window
        click button "OK"
    end tell
end if
I guess this is an ok solution... bit hard to identify windows when they don't have titles...
BUT this is not my main problem. The main problem is that the script gets to one of these alert dialog boxes and just sits there... It sits there for like 10 seconds and then it performs the "click button "OK"" command.
This is a problem as there are like 3 of these instances and it really adds up. Can anybody help me... I am using Acrobat Professional 8.2.0 and the entire code is:
tell application "System Events"
    try
        tell process "Acrobat"
            -- Enable security settings
            click menu item "Properties..." of menu "File" of menu bar item "File" of menu bar 1
            tell window "Document Properties"
                tell tab group 1
                    click radio button "Security"
                    tell group "Document Security"
                        click pop up button 1
                        click menu item 2 of menu 1 of pop up button 1
                    end tell
                end tell
            end tell
            tell window "Password Security - Settings"
                click pop up button 1
                click menu item 4 of menu 1 of pop up button 1
                tell group "Permissions"

A delay does not work... its like as soon as I click the "OK" button it stalls for 10 seconds or does not know that is meant to continue... because I did this:

For the past month (since Oct 11,2012) reporting services (SSRS 2008R2) is not starting after the server is rebooted. The service is set to automatically start and starts manually without a problem. The system event log contains the following error:
Event ID 7009: A timeout was reached (30000 milliseconds) while waiting for the SQL Server Reporting Services (MSSQLSERVER) service to connect.
SQL logs :
The SQL logs has many "Event 18456 Login Failed, State 38" errors when the database engine starts. I assume clients conections are failing because the databases aren't online yet. None of these 18456 errors coorespond to the account reporting services
runs under.
The SQL logs indication Event 7009 occures before the "ReportingServer" database is online so im assuming there is a dependancy but I don't know how to avoid this.
This problem is occuring on a number of our servers running SSRS (if not all)
Any ideas?
Paul

Hi A141695,
For Event ID 7009, you can try to do the steps below to resolve it.
    1. Click Start, click Run, type regedit, and then click OK.
    2. Locate and then click the following registry subkey:
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
    3. Right-click Control, point to New, and then click DWORD Value.
    4. In the New Value #1 box, type ServicesPipeTimeout, and then press ENTER.
    5. Right-click ServicesPipeTimeout, and then click Modify.
    6. Click Decimal, type the number of milliseconds that you want to wait until the service times out, and then click OK.
For example, to wait 60 seconds before the service times out, type 60000.
Quit Registry Editor, and then restart the computer. For more information about it, please see:

Startup problem with Lion OS 10.7.3

Just recently, I've been experiencing a startup problem with Lion. I don't usually have any issues running my Mac, so I'm at a loss why this is happening now.
I have an Intel Mac Pro running 10.7.3. I usually leaving my Mac running all the time and only restart when the need arises. In addition to being my main computer, this mac alsocontrols a MacMini that serves as a music server thru screen sharing.
This past weekend, I restarted my Mac and could not get past the grey screen. The mac chimes, the apple logo appears with the spinning gear, the blue screen briefly appears, but instead of progressing to the desktop it reverts to the grey screen with a repeating cycle of the spinning gear appearing (spins for a while, stops, disappears, reppears spinning, stops, disappears, over and over) - never progressing beyond that stage.
I decided to reinstall the system and things have been fine for the past few days. Today, restarting again resulting in the same problem.
I've tried several things without success. I disconnected all peripherals, reset the PRAM/SMC, ran Disk Utility from a install volume and ran repair and permissions (no problems reported). Tried safe mode startup - a progress bar appeared but never fully progressed and could not get to the desktop.
Recent changes included updating the OS to 10.7.3 and Adobe Photoshop CS5.5 - no recent hardware changes. No bluetooth devices connected.
Any thoughts? Thanks -

Thanks -
I've reinstalled the OS today and am back up and running.
But, since this is twice this has happened within the past week, I'm worried about might be causing this issue - besides bad luck. My Mac is usually rock solid - can't remember the last time I've had to reinstall the OS in the past few generations of OS X.

Mysterious repeat log entries in System events log

I tried unsuccessfully to share internet connection with 2 iMacs without router(That doesn't matter). But after this, my iMac (24" 2.8 GHz) not networked or on internet now shows this repeated log entries every minute:
com.apple.launchd[1] (com.apple.InternetSharing): Throttling respawn: Will start in 10 seconds
This message gets repeated every minute on System events log. Daily, Monthly maintenance was not done automatically earlier today on this iMac (usually it did without any problem) which was on all-night.
I checked with Disk Utility, repaired permissions. Although no problems in working, this continuous log writings disturbs me.
Thanks for any help & Happy New Year!
Best.

Thanks, V.K. Did that (was asked password). System log showed after restart:
com.apple.launchd[1] (com.apple.InternetSharing[152]): Exited with exit code: 1
com.apple.launchd[1] (com.apple.InternetSharing): Throttling respawn: Will start in 10 seconds
com.apple.launchd[1] (com.apple.InternetSharing153): Exited with exit code: 1
com.apple.launchd[1] (com.apple.InternetSharing): Throttling respawn: Will start in 10 seconds
Then it started again the same way as above - with each aditional line each time as shown above. Thanks for sticking with me on this. Hope you will offer other suggestions.
Best.

GUI event handling problems appear in 1.4.1 vs. 1.3.1?

Hi,
Has anyone else experienced strange event handling problems when migrating from 1.3.1 to 1.4.1? My GUI applications that make use of Swing's AbstractTableModel suddenly don't track mouse and selection events quickly anymore. Formerly zippy tables are now very unresponsive to user interactions.
I've run the code through JProbe under both 1.3 and 1.4 and see no differences in the profiles, yet the 1.4.1 version is virtually unusable. I had hoped that JProbe would show me that some low-level event-handling related or drawing method was getting wailed on in 1.4, but that was not the case.
My only guess is that the existing installation of 1.3.1 is interfering with the 1.4.1 installation is some way. Any thoughts on that before I trash the 1.3.1 installation (which I'm slightly reluctant to do)?
My platform is Windows XP Pro on a 2GHz P4 with 1GB RAM.
Here's my test case:
import javax.swing.table.AbstractTableModel;
import javax.swing.*;
import java.awt.*;
public class VerySimpleTableModel extends AbstractTableModel
private int d_rows = 0;
private int d_cols = 0;
private String[][] d_data = null;
public VerySimpleTableModel(int rows,int cols)
System.err.println("Creating table of size [" + rows + "," + cols +
d_rows = rows;
d_cols = cols;
d_data = new String[d_rows][d_cols];
int r = 0;
while (r < d_rows){
int c = 0;
while (c < d_cols){
d_data[r][c] = new String("[" + r + "," + c + "]");
c++;
r++;
System.err.println("Done.");
public int getRowCount()
return d_rows;
public int getColumnCount()
return d_cols;
public Object getValueAt(int rowIndex, int columnIndex)
return d_data[rowIndex][columnIndex];
public static void main(String[] args)
System.err.println( "1.4..." );
JFrame window = new JFrame();
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
Dimension size = new Dimension(500,500);
panel.setMinimumSize(size);
panel.setMaximumSize(size);
JTable table = new JTable(new VerySimpleTableModel(40,5));
panel.add(table);
window.getContentPane().add(panel);
window.setSize(new Dimension(600,800));
window.validate();
window.setVisible(true);
Thanks in advance!!

Hi,
I've fixed the problem by upgrading to 1.4.1_02. I was on 1.4.1_01.
I did further narrow down the symptoms more. It seemed the further the distance from the previous mouse click, the longer it would take for the table row to highlight. So, clicking on row 1, then 2, was much faster than clicking on row 1, then row 40.
If no one else has seen this problem -- good! I wouldn't wish the tremendous waste of time I've had on anyone!
