I recently switched from running Roon ROCK on a 10 yr old MacBook Pro to an Intel NUC. On the MacBook I had a few hundred CDs saved to the hard drive that I burned about 8 years ago. I was listening to these CDs and Qobuz while using Roon with the MacBook. I recently switched Roon from the MacBook to an Intel NUC. Since I’ve switched to the NUC, on the top of the Roon menu there is a curved line that is going around in a circle that seems to indicating that the software is looking for something. If I tap on the curved line, a box comes up (see screen shot above) with the following - Adding music to library: of 20401 tracks, 17675 added, 17518 identified. It has been doing this for a couple of weeks without any of the numbers changing. I also noticed that it never transferred over the CDs I had on the MacBook to the NUC. What is going on with the curved line going in a circle? Is it trying to transfer music form the MacBook? How do I transfer the music from my MacBook hard drive to the NUC? Have I used up entire 2TB SSD (I have a lot of DSD albums on the NUC)? Something else?
I am somewhat helpless with computer tech so that may be part of the problem. Any assistance would be greatly appreciated.
