    Thanks for confirming this is a software issue.  Now we need to find a way to get Apple to deliver a proper fix; not sure how that's normally done, but I'm going to visit my Genius at the bar and see if he has any ideas.


    I know these errors happen, but I'm hoping Apple will step up and fix it for us.

    Well after the 10.8.5 updates my Macbook Pro developed the black band on the external monitor problem and has now died completely. No power even though the PSU is outputting the correct voltages. Conincidence? It could be.


    Anyone any ideas of what tests I can do inside the Mac to establish if the problem is hardware related? I have as mentioned tested the power supply it is ok.

    I have an early 2008 15" MBP 4.1 which froze after upgrading to 10.8.5 (from 10.8.4). I couldn't do anything, it froze as soon as I tried to start a program. I didn't have a backup for 10.8.4 so I decided to reinstall 10.8.5 (not clean) and that fixed my problem. So it is possible to run 10.8.5 on an old MBP.


    I rebooted with alt pressed and chose the "Recover from" alternative. I chose reinstall OS (I had to enable WiFi) and after aprox. 30 min of installation it rebooted and has now been running for 3 days without problems.

    Macbook pro i7 17" mid 2009 8gb memory hibread Hard drive


    I installed the update yesterday, ive been running 10.8.4 no issues, laziness took over and i didnt back up 1st, my last backup was 3rd sept


    Today my internet connection kept failing, on checking on my other mac which ive left on snow leopard ... ! internet connection was fine.


    rebooted my router and mac and all seemed well for around 3 mins, then the internet went off again, so I rebooted, a few mins later, pointer froze, rebooted, then the startup froze, rebooted then the chime repeated over and over and over ...


    I restored the time machine to one i did this morning, formatted the drive and re installed the backup from today, so far so good, but if it freezes again I will copy over all the files from 3rd sept onwards (work) and restore back to 10.8.4


    I moved away from PC's in 2009 for this very reason ....snow leopard update I couldnt connect to my wireless drive,  on the lion update I lost battery life, now this ... COME ON APPLE, I PAID £2500 for a Mac not a PC !!!

    I'm experiencing major trouble after 10.8.5


    I'm running an early 2009 20" iMac (MB417LL/A). 8Gb Ram, 320 Gb HD. Originally had 10.6, skipped 10.7, installed 10.8 when it was released and updated each time all the way to 10.8.4.


    Since 10.8.5 was installed the machine is close to going out the window. If I have an external drive attached (NTFS format as I only use it RO on the iMac) it will refuse to boot to the GUI but I can still log in via an SSH session from another machine. System will also occasionally fail to boot to GUI with a network cable attached. Beach-ball of death is a regular occurrence. Sometimes have the spinning thing from the boot screen (propellor/windmill type thing) on screen permanently when it's booted to the GUI.


    Just backed up all the stuff I need and trying to do a clean install of 10.8 from USB key. However, when trying to create the USB key in Disk Utility it comes back with "Could not restore - Invalid Argument" even though I used this same image a week ago on a MacPro.


    Seriously fed up with this at the moment.

    Hello All,


    I have a late 2011 MBP 13" and I have excatly the same freeze issues. mostly when attempting to log in after closing the machine or after machine goes into sleep. However, the error is not exclusive to that condition in that the machine will freeze sometimes while im browsing on the internet or working in mail. This started after I upgraded to 10.8.5 from 10.8.4.


    So - not "old" MBP


    I have also reset the SCM and PRAM. without success


    for those interested - since I agree that I should not, as a consumer, have to wonder about the stability of my computer or its supplier provided updates being suspect - these are my machine specs:


    Model Name:MacBook Pro
      Model Identifier:MacBookPro8,1
      Processor Name:Intel Core i7
      Processor Speed:2,8 GHz
      Number of Processors:1
      Total Number of Cores:2
      L2 Cache (per Core):256 KB
      L3 Cache:4 MB
      Memory:8 GB

    Ok well after re intalling 10.8.5 BACKUP all has been well, until 10 mins ago, wifi started going off again, then the machine started to freeze again, after several restarts, i got a mesage when clciking wifi which said no wifi hardware installed ... I believe part of the 10.8.5 was a wifi update ?


    I restarted and held apple r went into the menu did a disk check all fine, restarted and im on it now all seems ok


    later today I will backup all my files from 3rd sept then reinstall 10.8.4 my last backup point for this version ...


    Apple is now costing me time and money ... im not a gamer my mac is for my design business...

    Im beginning to re look at the PC market. at least when you spend a 1/3rd the price of a mac, you can accept issues like this ... pffft !

    Fixed the problem - I'm not technical so bare with me


    After a lot of internet research and forcing the macbook to freeze consistantly i figured it was something to do with waking up the HDD / SSD after pause or sleep - so energy saving.


    Anyway I learned from the SSD manufacturer that a stability issue in certain cases for memory or SSD devices does occur and in my case the issue could be resolved with a firmware update.


    I followed the instructions which included creating a boot USB disk and runinng a piece  of software at boot time thus updating the SSD firmware.


    Result is that The machine has run for 24 hours without fail even after me trying to force the freeze situation as I did consistantly previous to the update.


    Dont know if this helps

    Late '11 15" Pro here. Installed the .5 update on Saturday - but didn't use it much after that until this morning. Woke it up to weird video glitches and after hard freezes, reboots, kernel panics and SCM, PRAM reset it it's DOA. I can get to bootmanger and the FileVault preboot loging screen but they have horizontal blue lines across and won't boot OS X (locks at a grey screen now) and my Win7 bootcamp on a separate drive (where the DVD used to be) has thick vertical blue bars and BSODs entering the desktop saying it was unable to reset the video driver - timeout.


    So I think the update fried my video chip.  I started a thread here


    Really bummed

    I have an early 2009 MacBook Pro (5,1).   I recently upgraded from 10.6.8 to 10.8.5.  I have been getting system freezes at least once a day.  Appears to be when in a full sleep or display sleep mode. 

    I cannot go back to 10.8.4, as some have reported, because I was on a much older version before the move to Mountain Lion.    I may have to go back to the Snow Leopard.


    couldn't really find anything useful in the console logs.

    in the last couple of days, I have noticed the freezes seem to occur only when on external power.  It's still fairly random, and I'll keep an eye on the power thing.



  • philbert830 Level 1 (0 points)

    had the daily freeze again.  power source is not a factor -- happens when on battery or external power.  and today it was not associated with any sleep state; I was actively using the computer, and it simply became unresponsive.  Never had this issue in 4 years of using Leopard and Snow Leopard on this device.

    I have tried zapping the PRAM/SMC a couple of times, so I guess doing that has not solved the freezing issue.

    This is awful.  Even my Windows systems are more stable than this.

  • wrlck Level 1 (0 points)

    I had that once while working on a doc - the machine just froze and I had to power down. Does your machine have an SSD drive? I fixed my freeze issue by updating the SSD firmware. my drive is an OCZ-Vector in case this helps.. been running since 3 October without a freeze.

  • philbert830 Level 1 (0 points)

    Thanks for the info.  I have a Seagate Momentus XT 750GB Hybrid drive [2nd gen, ST750LX003] that I've been running for about 2 years.  I've been checking the Seagate site every few months to look for firmware updates, but they don't have any for my specific drive.  I don't think there's been an update since I put the drive in 2 years ago.  The product is now discontinued [they have a new line of hybrid drives], so I don't expect any miracle updates from Seagate for this.

    Perhaps now I should move to a full SSD; I had been playing with the idea even before this episode.


    Note: I rolled back to my 10.6.8 backup earlier today, and everything has been working great.  Just cannot have daily freezes on my primary system.  Perhaps I'll try 10.8.5 again if I get an SSD [or wait for 10.9].

    I think I have solution after a long way...


    In 10.8.5 and 10.9 when I turn off wifi my mac freezes immediatly.


    to solve it

    I boot on my "secours" disk with OS 10.8.4 and i delete this file from the frozen system :




    reboot on 10.8.5 or 10.9 and don't turn wifi off again


    and it works


    I hope Apple can fix it
