MacOS w/ M3 MacBook Air...tried Lucida, tidal-dl, streamrip, and MediaHarbor but hitting walls at every turn. Where can I download high res music files with ease??

I've tried them all. Lucida throws an error every single time. Couldn't get tidal-dl or streamrip installed with command line -- followed directions to a T. Then stumbled on MediaHarbor app and Sequoia is blocking it -- "“MediaHarbor” is damaged and can’t be opened. You should move it to the Trash." Thought this was going to be WAYYYYYY easier. Ya girl just wants to re-build her music library. Help!
