Q: Installed Mavericks and now my system partition needs repair

Hi All,

 

I upgraded to Mavericks yesterday, but after the install my MBP's performance/responsiveness was substantially degraded.

 

Today (after reading posts from users experiencing similar issues on the forum) I ran disk utility. After verifying the disk, the utility told me there was a problem with my system partition, and that I would need to run disk utility from recovery mode (cmd + r).

 

I did so, and when I verify the disk from recovery it returns: "The partition map needs to be repaired because there's a problem with the EFI system partition's file system". When I attempt to repair the partition, I receive an alert that: "Live file system repair is not supported".

 

Now I can't even boot into the log-in page, and the only area I can access (aside from the blank grey screen with a picture of a folder on it) is the recovery mode. I would really like to avoid re-installing Lion from recovery mode and losing all my programs, settings, etc. Any advice would be much appreciated.

 

Thanks in advance.

MacBook Pro, OS X Mavericks (10.9)

    I had the same issue with the Time Capsule.  Mavericks changed its name for some reason and kept pinging it.  I think the incessant harrassment of that drive and calling it names is what killed it.  Mavericks also messed up the boot sectors of my internal drives on two different iMacs and caused Safari to stall the whole system on a regular basis.  I had a heck of a time getting back to Mountain Lion, which Apple support will tell you is no longer available through the app store (it is).  What a ridiculous mess.

    Bonjour, Hi,

     

    IN FRENCH

     

    La "Journalisation" doit être activée pour que la commande diskutil verifyVolume par exemple soit prise en charge.

    Pour activer la" journalisation" il suffit d'ouvrir une fenêtre du "Terminal" et d'y écrire:

    diskutil enableJournal /

    Ce n'est pas une solution miracle à vos problèmes mais cela pourrait résoudre des questions sans réponses.

     

    Cordialement

     

     

    IN ENGLISH

     

    Hello,

    The "Journaling be enabled for diskutil verifyVolume example is supported.

    To activate the "journaling" just open a window "Terminal" and write there:

    diskutil enableJournal /

    It is not a miracle solution to your problems but it could resolve unanswered questions.

     

    Cordially
