    Accidental deletion of CoreWLAN
    I did something really dumb. I deleted this file.

    /System/Library/Frameworks/Core.WLAN.framework/Versions/Current/CoreWLAN

    This file is used for WiFi I believe. I know this was dumb, I did not realise this was a file I thought it was a folder...

    Anyway, I can not log back into my mac. When I start in safe mode after a half day it does not get me to the login screen.

    When I start using Ctrl-S, I can see my files on the command line but only have read access, so I cant copy it back in from another mac.

    I can't connect to online recovery because this file is missing.

    Does anyone have any help for a poor dumb soul who can get into his mac book pro. 10.8

    Thanks.

    Did you try your Recovery partition? Start up holding "Option".

    This looks helpful, I can get into the recovery partition using the Option key.

    In there I can open a command prompt, but how can I copy the missing file that exists in the recovery partition into the real partition?

    I don't believe the file is on the Recovery Partition, see this Article, OS X: About OS X Recovery.

    Do you have a Time Machine backup or clone you can move the file from?

    I don't have any backup.

    I can see the file I need when I boot into the recovery partition and I have the file also on a USB key. I just need to get it copied to here on my normal Machintosh HD partition..

    /System/Library/Frameworks/Core.WLAN.framework/Versions/Current/CoreWLAN


    I do also have the option of reinstalling the OS, but I see this as a last resort..

    Maybe I should just do the re-install. According to these instructions I will not loose my user data, the install will just re-write my system files.

    Does this seem correct?

    I found this, The Unix Command Line: Files & Folders, but I am not comfortable with Terminal that much.

    You can wait for the more experienced Mac-Forums users to come by, or just do the reinstall. Sorry and good luck.

    Yes, that does sound correct.

    The problem is not that I don't know the cp command it is that when I am using the terminal in recovery mode I cannot see the location on the main partition where I want to copy the file to. If I could get a terminal open on the main partition that is not read-only and I can mount a USB I am happy but this does not seem possible.

    Got it, your help def got me on the right track. Using terminal when booted into the recovery partition I was able to navigate to the corrupt file on the Macintosh HD partition via


    /Volumes/Machintosh Hd/.....


    Then I copied the file from the recovery partition to there.


    Back in action again, thanks for the help.
