OS X Mountain Lion 10.8.1 Update

OS X Mountain Lion has been updated to 10.8.1, the update is a general maintenance and bug fix release which includes assorted improvements.

The OS X 10.8.1 update can be downloaded through the Mac App Store, either launch the App Store directly or access it through the  Apple menu by selecting “Software Update”. The download is fairly small, ranging from 8MB to 30MB depending on the Mac, and you will need to restart the Mac for the Mountain Lion update to finish installing.

The official change and improvements list is as follow:

  • Resolve an issue that may cause Migration Assistant to unexpectedly quit
  • Improve compatibility when connecting to a Microsoft Exchange server in Mail
  • Address an issue playing audio through a Thunderbolt display
  • Resolve an issue that could prevent iMessages from being sent
  • Address an issue that could cause the system to become unresponsive when using Pinyin input
  • Resolve an issue when connecting to SMB servers with long names
  • Address a issue that may prevent Safari from launching when using a Proxy Automatic Configuration (PAC) file
  • Improve 802.1X authentication with Active Directory credentials

Though some individuals have reported improvements, there is no direct mention of the wireless dropping issues that some Mountain Lion users have encountered, and there is also no mention of the reported battery life drain that effects some Macs with 10.8.

All OS X Mountain Lion users are recommended to install the update.

Update: The popular “purge” command to clear inactive memory is broken in OS X 10.8.1 update, developers and users who use the command frequently may want to put off updating to 10.8.1 until a fix is available. Running the command issues the following error:
Used “purge” command in terminal and received the following error:
[ERROR] The device-file for this operating system, ‘osx-12.1.0.xml’, was not found. An attempt to revert to a previous revision of the OS devise-file: ‘osx-12.0.0.xml’ has been made. Please file a Radar report with Apple, on the ‘CoreProfile’ component, version ‘X’.

    As of update 10.8.2 purge no loger throws an error!!

    As for Yevgen’s comment: I don’t mind typing purge into the terminal every once in a while. (I pretty much always use sleep mode and never turn my mac off).

    I switched to mac from windows about 1 1/2 years ago and i’m never looking back. Windows memory management is the worst!!

  2. Stark says:

    I got this problem.Putting “purge” in Terminal appearing the Error.

  3. Yevgen says:

    Well, purge works yet throw the message but I’ve another rhetorical question — WTH do we have to use purge at all?! Isn’t there suppose to be Memory Manager like in any other OS? What about that fabulous Grand Dispatch or whatever they call it? I’m finding this ridiculous being forced to run purge from time to time just making OS X working just normal instead of sluggish crawling through.

  4. Rick says:

    I have a number of problems in 10.8.1. Right after the update, my mac went into a safeboot and froze.

    Another small but annoying thing is that my notification icons have become broken and pixelated. I put a link to a screenshot of it below.

    I have a much bigger need for 10.7.5 on my wife’s computer (which is a year older than mine and won’t take Mountain Lion). 10.7.4 broke her resolution to only extremely large and extremely small, and it’s a real pain to use. Testers say that’s been fixed in 10.7.5 for a month or more, but Apple won’t tell us when it will be available for customers.

  6. Nevin says:

    To those of you who are _not_ getting the error: do you have a file:

    /System/Library/PrivateFrameworks/CoreProfile.framework/Versions/A/Resources/Devices/osx-12.1.0.xml

    as well as osx-12.0.0.xml in the same directory?

    If so, how do they differ?

    I too get the level 3 syslog error. Since level 3 errors are not critical, I helped the ‘purge’ command along by doing, in the above directory:

    sudo ln -s osx-12.0.0.xml osx-12.1.0.xml

    The soft symbolic link the above command creates stops the error. I think this is _probably_ safe to do and forget about for the following reasons:

    the purge program falls back to the linked file anyhow, though complains on screen and in syslog(Console)

    the symbolic link is non-destructive, and should a real 12.1 file be installed with proper credentials, it will overwrite the link

    if one were to have a 12.1 file in place already, the ‘ln’ command would simply say ‘file exists’ and exit non-destructively.

    I’m not sure why purge references a file that may or may not exist, nor why it treats its absence as an error, when that may or may not be the case. I don’t think it’s reason to put updating ML on-hold, in any case… it is _not_ a critical error.

  7. Domenikus says:

    Same problem here.

  8. Helene says:

    I have the same issue. It’s not really a big problem. The “purge” do free up memory when invoked. Working and verified. The error message states that it uses an older version of the configuration file. This is an xcode-cmd-tools issue i think.

  9. eshria says:

    Hi guys,

    Since I installed 10.8.1, i’ve got the same problem.

    When i use the command “purge”

    [ERROR] The device-file for this operating system, ‘osx-12.1.0.xml’, was not found. An attempt to revert to a previous revision of the OS device-file: ‘osx-12.0.0.xml’ has been made. Please file a Radar report with Apple, on the ‘CoreProfile’ component, version ‘X’.

    But the command “purge” works. Just this message…

    I have not idea for fix it

    thanks
    xoxo,

    • John says:

      Yeah, I’ve an automator which work properly on OSX 10.8.1 without error message; it use purge…

      If u want, i can send it to u…

      John

      • Eshria says:

        Hey ;)

        Thank you John.

        But I erased everything, i mean, there were too many things that bother me with 10.8

        So go back 10.6.8 :) it’s my love, my dream 10.6.8 forever :P

        Sorry ^^ i’m losing my mind xDD

        It was nice, thank you ;)

        • John says:

          Not at all…

          OK, U know, but 10.8 is very fantastic OS, just this update is not cool…
          Which Mac have U? -if possible to ask this…

          My experience:
          the little “old” ie before 2010’s Mac dont like the 10.8 OS.

          …but U like Snow Leopard, then OK.

          Good Snow Leoing!

  10. sault says:

    No error message here.

  11. Aberto I says:

    Two months for an update that solve almost nothing…
    Bravo Apple!

  12. Winski says:

    10.8.1 DID NOT ADDRESS the MBP battery utilization issue. The battery still drains at an amazingly rapid rate.

  13. Michael says:

    This update did NOT fix my wi-fi issues. Just a FYI.

  14. H says:

    @B
    I can confirm that is not the case, and I am so very disappointed. I have never had any wifi issues before, but after the ML upgrade it sucks. I am able to use the wifi connection for a couple of minutes, then it slows down and then it stops.

    And I have tried everything that you can imagine even upgrading the router’s firmware though it was a problem that came when upgrading.

    • steven says:

      Did you try the MTU solution? I dropped mine to 1400 and it stopped my wi-fi problems with my home router. Never had an issue with work routers or friends though, seems dependent on connection and maybe even band.

      • H says:

        @steven
        No I hadn’t tried that but now I have and no success. It’s like it first slows down and then it stops.

        Thx anyway.

        • Don says:

          I have the same issue and disappointed to hear it is not resolved by Apple, very disappointed.

          I tried all the suggestions of MTU and new location and even router firmware update but in the end the issue appears to be 802.11n 5ghz band. I disabled it on my router and have not had any dropping. This to me is not fix but a bandaid and stinks.

  15. smrt says:

    Before this patch I saw gaps in screen switching animation. 10.8.1 seems at least improved the animation.

  16. Isrefel says:

    Have just confirmed that purge does still work, despite the egregious error message.

  17. Timur says:

    After update, I have no longer left with inactive memory, so I guess purge is no longer needed

  18. Isrefel says:

    @B I actually never had wifi issues personally, but I am now noticing that wifi consistently fails to connect to my network properly at login. I have to shut it off and turn it back on to get a connection

  19. B says:

    Can anyone confirm if this fixes the wifi issue?

    • Tieteense says:

      I was able to re-enable my wifi b/g/n; whereas before the update I had to downgrade it to g only. Custom MTU no longer required, although I had to run the diagnostics tool twice and restart for it to pick up my network properly.

    • Tieteense says:

      Wifi upgraded back to b/g/n at 300Mbps, whereas I had to put it into g only mode for this Macbook to work. Customized MTU no longer required here. Took a restart and a couple of diagnostics for it to pick up my network information properly.

    Parental Controls are still effed up. :( >:-|

  21. Isrefel says:

    @AG I am also having this issue post 10.8.1 update. I started a thread over on MacRumors — http://forums.macrumors.com/showthread.php?t=1427706

  22. Greg says:

    Also, my mac has been going to sleep really often in 10.8 sometimes it tries to sleep when it’s copying data or other things. I think victor cajiao also said he has the same issue as me. Victor has been on a podcast recently on maccast three amigos.

    Updated to OS X Mountain Lion 10.8.1

    • zoly says:

      @AG: I also used the “purge” command and received NO error message on OS X Mountain Lion 10.8.1

    • Paul says:

      I have confirmed the error using the purge command, updated post to reflect this. Hopefully a fix will be found soon.

    • steven says:

      The command still works, it just throws out that ridiculous error message. Watch Activity Monitor while you run purge though and you will see Inactive Memory clear out.

      • Dean says:

        I just tried using Purge and watched Activity Monitor. I had just over 2gb of inactive memory. Entered Purge and it dropped to 1.41gb of inactive memory (and got the error message in Terminal). Ran Purge a second time and had no drop in Inactive Memory (and got the error message again).

        I hope this is fixed, I Purge several times a week or more.

        • hellrotbill says:

          I ran purge on my 10.8.1 and it did go from 2.10 GB free to 4.08GB free. I did see the error though:

          The device-file for this operating system, ‘osx-12.1.0.xml’, was not found. An attempt to revert to a previous revision of the OS device-file: ‘osx-12.0.0.xml’ has been made. Please file a Radar report with Apple, on the ‘CoreProfile’ component, version ‘X’.
