Macbook Pro mid-2012 Disk Utility First Aid Results Interpretation Help My MacBook pro mid-2012 has been acting a little odd lately (freezing, losing track of files). I've run first aid in disk utility multiple times, but always get the same notes which suggests it doesn't fix them (see below). I've booted into recovery and disk utility tells me the hard disk is ok and still shows these same results. Are these results anything I should be worried about? Thanks!

If you're worried about "Volume could not be unmounted", it just means that the file system is in use while you're checking it. It does not mean that anything is wrong with the drive or the file system.
