I'm still stuck I installed MC on my macbook which has never seen hdtracks and it worked just as expected. I could see albums and artists when I did an import from Music that matched what itunes shows. I tried completely uninstalling MC18 with Mr C's kind help, but upon reinstall and import from Music, I only saw the HDtracks sampler artists and albums. So I moved those files and folders, completely uninstalled MC 18, and reinstalled MC 18 and no joy. All the same files under Music that were ripped via itunes still show up in MC 18 Albums and Artists as unassigned. They play fine, but I have no covers or groupings there. I can see album names as folders if I drill down into Files. The HDtrack sampler files, folders, albums and artists are gone, as expected.
I know little of computer audio, Mac OS, or files systems, and nothing about tagging. Please help, any direction on what to try or research next would be very appreciated. I also see I'm burning through my annual restore limit. Should I be concerned? I'm using MC 18.0.216, tia.
