For the past week I have been experiencing intermittent hangs and crashes after the 10.8.3 update. I took it in store, after a few days testing they said they could not find anything wrong and that they were able to run multiple apps with no problems. Since i've had it back the problems have continued, even in safe mode and with a newly added user account. I trashed cache, java and flash which seemed to have made a difference; more responsive and any hangs didn't last long. After 30 mins of web browsing, the mechanical gear has shown up on my desktop and the cursor has disappeared. Could anyone suggest solutions to this problem?

MacBook Pro, OS X Mountain Lion (10.8.3)

    Have you tried repairing your hard drive and permissions?


    If that doesn't work, I'd reinstall 10.8.3 over your current install.

    If that doesn't work, I'd back up my documents, erase the drive, and do a clean install.

    Does it kernel panic, or just freeze and crash applications?


    If they say it ran without problems, what hardware do you connect to it that you didn't have connected when they checked it?


    How do you connect to the internet? Do you use some sort of USB aircard or other dongle?

    Yes i've tried repairing hard drive and disk permissions, using both utilities and an app called 'cocktail' to no avail.

    I'll give reinstalling 10.8.3 a go.


    The Diagnostic Report shows only Spin, Hang and Crash, no Kernel panics.

    I use no additional hardware. The problem usually occurs after using any web browser, i don't recall them mention using this. I've uninstalled and reinstalled chrome which hasn't made much of a difference. Safari equally as bad.

    If it is while using a browser, any browser, then it could be one of the other plug-ins in the /Library/Internet Plug-ins folder.

    Try dragging them all to a folder on your desktop and start Safari. If all goes well, add the plug-ins one by one and see what happens.

    If it doesn't help, you can move them all back into the folder.

    Some people who updated from 10.8.2 have had problems that were resolved by installing the 10.8.3 combo updater from the Apple Support download page. I'd suggest a complete reinstallation in Recovery mode. Back up all data first.

    Just an update, thank you all for your replies. I attempted all the suggestions but they had little effect. I did a complete reinstallation and even then the laptop was sluggish when using safari or chrome. I have found that removing the chrome file from preferences leads to better performance.

  • Linc Davis Level 10 (192,887 points)

    That file couldn't possibly affect anything but Chrome.

    If the re-installation used the original user account, the problem may just have been brought back.  Perhaps resetting Safari and clearing the cookies may help, also, disabling add-ons and updating Flash is a must, if you use it.  I would use the automation script in OnyX to clean out caches etc, but some people are averse to using third party tools like this.

  • Somajoe Level 1 (0 points)

    I am at a loss, the Onyx automation script couldn't be completed due to a crash and performance has got worse since. Why are these problems still occurring when i erased and reinstalled the hard drive?

    I'm not sure if its a related but there is no longer a humming sound when i turn the laptop on.

    It continues to crash in safe mode so i am unable to install the combo updater there, will it make a difference if i manage to install it normally? I did this before i erased the hard drive and it didn't make a difference.

  • arthur Level 5 (5,155 points)

    As putnik points out: Did you do a clean install, or transfer from a time machine or other backup?

  • Linc Davis Level 10 (192,887 points)

    If the system is crashing in safe mode after a reinstallation, then you have a hardware fault. Take the machine to an Apple Store for testing.

  • Somajoe Level 1 (0 points)

    It was a clean install. I don't use time machine, I did put some files on to a usb but i have yet to transfer them back on to the laptop so i can't see how it would be a case of problems being brought back.

  • Somajoe Level 1 (0 points)

    Would a hardware fault happen because of the 10.8.3 update? Everything was running smoothly before.

  • Linc Davis Level 10 (192,887 points)

    There are two reasons why a hardware fault might only be manifested after an update:


    1. The fault existed before, but a change in a driver or some other system component (maybe a new bug) brings it out.


    2. A hard drive that was on the verge of failing is pushed over the edge by a sudden burst of write activity during the update. This is the most common scenario.
