In the UI "about this mac" on my MacBook Air (middle 2011) the model is wrong, it's appear MacBook Pro. Does anyone knows why??? It was the same with the first update of Lion (10.7.1) and now with the upgrade ML too...

MacBook Air (11-INCH, MID 2011), OS X Mountain Lion

    Did you buy your mac from an authorized retailer? I'm not implying anything nor accusing you of anything, but if you bought it through someone on craigs list, for example, it may be possible they could have loaded counterfeight software or something of the like. Then again i'm just speculating.

    I'm buy it directly from the apple store online...with Lion 10.7 the info was correct, then, with the updates (I don't remember wich one - but sure with the 10.7.4) and now with ML too the info is MacBook Pro instead MacBook Air...but if I watch in the System Infos there is MacBook Air...i don't know why!?!

    It's not a standard MBA, but a customized, BTO...

    Weird.  Your Mac Book Air doesn't have a disc drive correct?  Otherwise you do have a pre 2012 Mac Book Pro!


    Post your Mac's info.

    Apple Icon > About This Mac > System Report


    It should come up with a summary of HARDWARE.  Copy/Paste the info into your reply.

    Do you have any ideas?

    It looks like your About this Mac knows it is a MacBook Air in the details.


    Where are you seeing it say MacBook Pro? The overview screen?

    I really don't understand...

  • sinoue Level 2 Level 2 (200 points)

    Hi Lupi26,


    You're problem statement was that the UI stated you had a MacBook Pro.


    Where are you seeing the UI that tells you your Mac is a MacBook Pro and not a MacBook Air?


    If you go to the Apple Icon > About This Mac > More Info


    What does this screen show?  I posted my UI screenshot of a MacBook Air for you to compare.


    To post your screen shot you can hold the command key and the shift key and then hit the "4" key to bring up the screenshot utility.  Drag the + icon around the screenshot you want to show.  You can crop it so your serial # doesn't show. 


    Then hit reply and use the camera icon to attach the screenshot image that is on your desktop to this message.

    I just tried switching my Mac to Italian and after restarting checked my About screen to see if I could recreate your problem.  I failed.  It showed up correclty, but in my case it still showed the English string translation for the model size and year (instead of 13 pollici, Meta 2011 I got 13-inch, Mid 2011).


    This makes me think there is a string translation error somewhere else.  I'd be curious if other Italian MacBook AIr users have the same issue.  If you change your system preference, language & text, from Italian to Enlgish I'm guessing it'll still show the same problem.


    Do you also own a MacBook Pro?  Supposedly the serial number is linked to the Mac model.  Did you ever reinstall the OS?  If every default install had this issue every Italian user would be running into it.  Might check the Italian forums to see if this is a known issue, or your setup is unique.


    Sorry I couldn't be of more help.  I'm guessing the error of identifying the wrong Mac is just a cosmetic issue, but I agree it is annoying.


    You might be able to hack the string to show the correct model, but I don't the correct steps, and for stability I'd recommend not changing it.  I think you should contact Apple.  Maybe you'll get a swapped out MacBook if they can't resolve it.

    I a have an "italian" 2012 13" MBA on which I have set english as default language.I have just checked out and the About screen shows the correct model in both languages.

    I am runnning Mountain Lion but I am sure it was correct with Lion as well.

    I do think you should contact Apple.

  • Lupi26 Level 1 Level 1 (0 points)

    It's a very corious thing...i'll contact the apple to have any information...thx for your help!

    Hi sinoue,

    i create a new user and the problem is's just a problem on my own user-account! But i don't know why!?!

  • Lupi26 Level 1 Level 1 (0 points)

    So i solved my hard /Users/MyUserName/Library/Preferences/ Profiler.plist

    it was the wrong description, wich you can simply change if open the *.plist with textedit...


  • sinoue Level 2 Level 2 (200 points)

    Congrats!  I have no idea how you figured it out, but hopefully it will help the next person with an incorrect about this mac account to edit the System Profiler.plist or create a new account.
