We've had our Macbook Pro for 6-7 mos now with no problems at all until about a month ago when we started seeing the little spinning color wheel showing up anytime we were running Safari. When this happens it basically locks up the system and doesn't let us access any other applications or functions. I've been able to get activity monitor up once or twice and it shows Safari using 99% of the CPU and it says "system not responding." This seems to happen regardless of whether or not we're on a web page that uses Flash from what i can tell.

I've been reading these threads and so far i've installed clicktoflash, repaired the disk permissions and also re-downloaded Safari 4.0.5. None of this has helped the problem at all. So, I'm wondering why it is that we've had no problems with Safari until 3-4 weeks ago when this issue surfaced and what else i need to do to get it fixed. Right now it's basically impossible to use our computer if we want to access the web...the color wheel comes up every few minutes and freezes everything for 2-3 minutes before it frees up again. Super frustrating...

    We've had our Macbook Pro for 6-7 mos now

    Are you running Snow Leopard???

    First, if you are running 10.5.7, you need to update your system software. Minimum requirements for Safari 4 is Leopard v10.5.8. *Click your Apple Menu/Software Updates.* If you have already updated to 10.5.8, please click My Settings on the right side of this window and update your forum profile. See requirements here: http://support.apple.com/kb/DL877' If you updated to v10.5.8 and Safari still freezes ...

    Uninstall then reinstall the most recent version of the Flash Player plugin.

    Uninstall Flash

    Install Flash

    *Now repair disk permissions...* Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and restart your Mac. Launch Safari. If it still freezes...

    Try uninstalling ClicktoFlash and see if that makes a difference. Go to ~/Library/Internet Plugins. Move ClickToFlash the Trash. Relaunch Safari. If it still freezes the system, try logging into another user account, launch Safari and see if the same thing happens. *If it crashes in another user account....*

    Right now it's basically impossible to use our computer if we want to access the web...the color wheel comes up every few minutes and freezes everything for 2-3 minutes before it frees up again. Super frustrating...

    Might be a good idea to check the start up disk for errors just in case.

    Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
    Go to Installer menu and launch Disk Utility.
    Select your HDD (manufacturer ID) in the left panel.
    Select First Aid in the Main panel.
    (Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
    Click Repair Disk on the bottom right.
    If DU reports disk does not need repairs quit DU and restart.
    If DU reports errors Repair again and again until DU reports disk is repaired.
    When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
    Select your start up disk and click Restart

    While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. Make sure there is always 10% to 15% free disk space

    If the startup disk appears to be ok and there's enough free disk space and Safari still freezes, then it's possible there's a font problem. Go here for help for Font Problems & Management

    Thanks Carolyn. We are not running snow leopard, we are running OS X Leopard 10.5.8 currently. I just went through and did everything you recommended except for the font stuff. There were no issues with the hard disk. I will let you know later today if the same safari issue is still occurring.
  • Bnuts Level 1 (0 points)
    Yep, same issue still occurring with Safari taking up 99% of CPU and saying "system not responding." Will look at the font stuff now, but if that doesn't solve it what is our next move?
  • Bnuts Level 1 (0 points)
    i also just did step 1 of that Cnet article by validating the font book and there were no issues. To be honest, step 2 sounds somewhat advanced (emptying font cache) and I'm not sure I want to do that unless you really recommend it.
  • Carolyn Samit Level 10 (102,825 points)

    Another way to empty font caches is to boot in Safe Mode

    It's takes a little longer to boot into Safe Mode then a normal boot but once you are in Safe Mode just click your Apple Menu and click Restart. Your Mac will reboot normally.

    Launch Safari. If it still freezes....

    Login to your Mac using a different user account. Launch Safari. If the same behavior exists, go here for trouble shooting 3rd party plugins or input managers which might be causing the problem. Safari: Add-ons may cause Safari to unexpectedly quit or have performance issues

    Bnuts -- If you've checked for duplicates, I think you're fine.
    If you had a font cache problem, you would be showing up with very weird characters for copy.
    And Safe Boot only clears the user's font cache, none of the others.

    Just curious --
    Have you cleared your Safari cache and History?
    They would be the first things be sure of, I would think.

    Still no luck guys...this is so frustrating! I've now noticed that Safari isn't even eating up the CPU on activity monitor but just says "system not responding" in red.

    I had cleared the history and cache previously and that hasn't helped. My wife has a different user profile and says she hasn't had the issue in the last few days but mine is unchanged. Every few minutes i get the little spinning color wheel and cant do anything for a few minutes. What else can i do here? Uninstall Safari and reinstall? should i just switch to firefox?

    oh and now the address bar is gone from safari as well and i can't seem to get it back....ugh!

    In case it helps others:

    After a recent "Archive and Install," Safari would frequently freeze. Not Responding, or CPU spike.

    I uninstalled Delicious Safari and that took care of it. The things you forget sometimes....
