Google search on “roon mac export hang beach ball” took me to this post at the top of the search.
Looks like i’m not the only one with this symptom.
For me, with Mac, latest Roon everything, Roon core running on Windows box:
What does not work: export “favorite” tracks from the Tracks list that has NOT been previously exported from the album view <<------ hangs, circling beach ball for few mins, followed by failure message,
What works: go to the album that has this “favorite” track, export from there, NO PROBLEM. Now, go back to the Trakcs list with the same favorite track, this time Exporting WORKS!
Top is export done from Album screen. Bottom is from export (successful) done from the Tracks list screen.
Seems like something about the Export from album screen causes subsequent export of the same track to succeed from the Tracks list screen.
