@support,
Copied a HIREZ file from mac desktop and it appears to be hung up in a loop and I do not see a command in ROON to abort the copy process. Appears to be hung up on the 14th file (track) out of 18.
One good free integrity checker for the Mac is Audio Health Check. It’s from the makers of the excellent audio metadata editor Yate. I have no affiliation with them but use both pieces of software.
