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)
