Hi, My Macbook Pro has been freezing and running poorly for a few weeks now, so I ran Disk Utility today and a screen came up to say the disk needs to be repaired. I then reset the computer, holding down command D, etc. However, when I ran Disk Utility it said that the disk was fine and couldn't get to the repair stage. I've attached a photo of the original disk utility screen. Any help? I have also tried to run the Mac repair thing resetting and holding down D, but it couldn't find the problem. Any help would be great.
