I have an older 2012 iMac which is currently running 10.13.4 or at least I think it is. However, whenever I run Disk Utility I get the following. ____________________ Verifying file system. Volume could not be unmounted. Using live mode. Performing fsck_hfs -fn -l -x /dev/rdisk0s2 Performing live verification. Checking Journaled HFS Plus volume. Checking extents overflow file. Checking catalog file. Checking multi-linked files. Checking catalog hierarchy. Checking extended attributes file. Checking volume bitmap. Checking volume information. The volume Macintosh HD appears to be OK. File system check exit code is 0. Restoring the original state found as mounted. Operation successful. __________________ Should I be concerned that the volume could not be unmounted. What does that mean and what is the impact on my computer. I run Disk Utility regularly and this notice that the volume could not be unmounted seems recent. Any help of info would be greatly appreciated. TIA Paul
