I am frequently seeing processes not repsonding in the Activity Monitor. This will happen numerous times a day, mostly with Safari & iPhoto. Less often Mail & Finder are included in the list. I have recently installed Firefox and the 'not respsonding' is less frequent than with Safari. I also had similar improvements with Chrome. I don't have to have both Safari/Firefox & iPhoto open, either will do. Also, playing music in iTunes, after a few tracks the music will pause of its own accord for quite a few seconds.

 

So, mostly in iPhoto or Safari, the spinning wheel will appear and the activity monitor will show iPhoto/Safari as Not Responing. This may continue for several minutes or more. I am able to swipe left & right to other desktops, but can't do anything in any program. For this reason I'm not able to Force Quit anything. The activity monitor will show cpu at 95% idle and plenty of free memory.  After several minutes the programs usually 'wake up' and the force quit option confirmation will appear  (if I have tried to initiate it from the Activity Monitor). Programs may then respond normally again, or go back to Not Responding.

 

If the hang goes on for too long and I power off using the on/off button the machine will more often than not take 10+ minutes to reboot. The apple logo will be on the screen for 5+ minutes and may take a further 5-10 minutes once the Desktop screen appears. Occasionally the apple logo as remained for about 30 minutes.

 

I have found the situation usually recovers itself better if I don't power off & restart, though sometimes it appears to be the only option.

 

I have installed more memory (4gb x2). Verified/repaired permissions. The iMac has had a couple of overnight stays in the Genius bar where the hard drive has been stress tested and hardware generally found to be working fine. They guided me through a clean install of OS X.

 

I don't recall having problems prior to the release of iPhoto '11.

 

I don't have any diagnostic information from before the OS X install (sorry, didn't realise it existed). Since the install I have:

User Diagnostic Reports

iPhoto - iMac.crash

PluginProcess - iMac.crash

System Daignostic Reports

Kernel - iMac.panic - pasted below

Pages - iMac.hang

Safari - iMac.hang

Safari - iMac.spin x2

 

I am not sure what to look for in the system log around the time of the hangs.

 

A kernel panic is very rare for me. I think it's pointing to the graphics card - NVIDAI GeForce 9400 256 MB. But could it also be the cause of the hangs?

  • Linc Davis Level 10 Level 10 (159,945 points)

    Uninstall the memory you added and restore the original memory. Any change?

  • croftcrew Level 1 Level 1 (0 points)

    Yes, sorry, in one of my visits to the Genius bar this was mentioned. I have tried with 1. The original memory only & 2. the Crucial memory only. Problems were repeated in both configurations. Originally I installed the extra memory in a bid to stop the programs hanging.

    Similaly the problem persists whether or not the firewire cable is connected (used for backup to external drive).

  • Nanthon_o Level 1 Level 1 (0 points)

    Quit any applications it is running than press hold down Option button and open iPhoto on dock menu .May be help..

  • Eric Root Level 7 Level 7 (32,885 points)

    Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.

     

    Isolating an issue by using another user account

     

    If the problem is still there, try booting into the Safe Mode.  Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application uninstaller. For each disable/delete, you will need to restart if you don't do them all at once.

  • croftcrew Level 1 Level 1 (0 points)

    A Genius did set-up another admin account and the conclusion was that it's a system wide. After the clean install the spinning ball etc was back before reloading 3rd party apps. As I'm seeing v. slow system starts after programs hanging, is it still possible it could be down to a 3rd party app?

    Thanks.

  • Linc Davis Level 10 Level 10 (159,945 points)

    Remove the Sophos product by following the instructions on this page. If you have a different version, the procedure may be different.

    Back up all data before making any changes.

  • croftcrew Level 1 Level 1 (0 points)

    Hi. I've removed antivirus. Will let you know if it makes a difference, though it was a reasonably recent addition to my mac and the 'not responding' problems were pre Sophos.

  • croftcrew Level 1 Level 1 (0 points)

    No change without Sophos. When booting into Safe mode, is it normal for Wired to be using over 75% of system memory?

  • Linc Davis Level 10 Level 10 (159,945 points)

    No change without Sophos.

     

    I assume that means you got another panic after removing Sophos and rebooting. Does the latest panic report include these lines:

     

    loaded kexts:

    com.sophos.kext.sav    8.0.14

     

    There's no need to post the whole report.

  • croftcrew Level 1 Level 1 (0 points)

    No, no panic. Still only had the one. The machine just continues to hang with 'Not Responding' processes in the Activity Monitor. Very frustrating as it comes & goes.

  • Linc Davis Level 10 Level 10 (159,945 points)

    Back up all data immediately as your boot drive may be failing.

        

    If you have more than one user account, these instructions must be carried out as an administrator.

     

    Triple-click anywhere in the line below on this page to select it:

    syslog -k Sender kernel -k Message CReq 'Chann|GPU D|I/O|Prev' | open -ef

      

    Copy the selected text to the Clipboard (command-C).

     

    Launch the Terminal application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.

     

    Paste into the Terminal window (command-V).

     

    The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.

     

    A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. The title of the window doesn't matter, and you don't need to post that.
