Hi,

 

I've had my brand new MacBook Pro 13inch 2.9GHz i7 8gb ram Mid-2012 model since around Sept/October time and I have had absolutely no problems with it. I am an experienced mac user and after the issues I've had before, I have taken extra special care with this macbook and have loved using every minute of it (almost everyday every second I'm awake!).

 

Anyhow, so yesterday I noticed that the loading of applications or just openning tabs inside of safari it was causing my macbook to hang for a little while, including watching movies in VLC player.

 

I did a disk verify and nothing was wrong, then I did a verify disk permissions and got the following;

2013-01-28 10:01:58 +0800: Verifying permissions for “Macintosh HD”

2013-01-28 10:15:38 +0800:

2013-01-28 10:15:38 +0800: Permissions verification complete

 

I then click repair and it seemed to repair everything fine;

2013-01-28 10:34:15 +0800: Permissions repair complete

 

 

I then proceeded with restarting the machine just to keep the machine a little fresh, but soon enough after restart I started having the same issues again. I ran verify disk permisions and there wasn't any more errors so could proceed to look there.

 

I then ran activity monitor and everything looked fine, however everynow and then when the computer would hang I would be almost hung completely except for moving between the screens.

 

I'm really stuck on how to fix this, can anyone help please? It's unusual and is starting to get frustrating as I need to sit and wait a couple of minutes every now and then before continuing to use my MacBook.

    You're under warranty - take the machine into your local Apple Store or an AASP and have them run diagnostic tests on the machine. I'm sure that the first thing that they will recommend is reinstalling OS X. You can save some time by going ahead and doing that by holding down the Command and R keys whilst booting, and then electing to reinstall the OS anew. It won't be a clean install, but it will be a fresh install.

     

    Before you do that, however, you might want to check to see if you've any third-party kexts that may be causing problems. In Terminal, copy and paste:

     

    kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'

     

    ...and then hit Return. Post any output from Terminal in a reply here.

     

    Good luck,

    I'd try removing the Soundflower driver - as I understand it, it hasn't been supported for almost 3 years. That might be the culprit right there. Move it to a folder on your Desktop and reboot - if you're no longer having problems, you'll know that's the reason!

    No telling where the kext is stored - usually they're in your root System>Library>Extensions folder, but different applications may place them elsewhere. Download the free "EasyFind" from the App Store and search for terms such as "soundflower" or "cycling74" - that should find it.

     

    I'm about 90% certain that's your problem.

    Your friend for finding system stuff is the System Profiler, aka "System Information", found in the Utilities folder. In the Software/Extensions section you can locate the desired item. May need to double-click the Extensions label to get it to update the list. There you will find that kernel extensions are kept exclusively in /System/Library/Extensions and have a .kext suffix.  If you take such a file out of that folder and restart, it will not be loaded.

     

    Be sure to positively identify which one is the errant kext before moving anything. Else you will be shooting self in foot.

    I think that, at this point, it's worth visiting your local Apple Store or an AASP. I've no idea why you're getting an estimated 6 hours to repair a block count... and I'm wondering if the disk is actually going to be successfully repaired or not.

     

    You've wasted too much time trying to 'fix' a machine that's still under warranty - take it to the Apple techs and let them fix the underlying problem.

     

    Good luck,
