Can't view and access files on a NAS
1 When I go to view the files on the NAS in the finder in the new iMac, I just see the swirly thing in the finder and the folders and files never appear in the window.
2 When I view on the new MacBook, I can sometimes see the folders, but the files never appear.
3 When I try to view the files on my old MacBook, I sometimes see the files.
4 My NAS is accessed by Sonos and iTunes and generally I have no problems even if I can't see files in the finder. But sometimes I have problems accessing files (i.e. I have had occasions when entire albums or entire song inventories of a particular artist are gone, only to magically and unpredictably appear a week later).
This has been constant experience for the months so isn't a once-in-time anomaly. So net, the newer, the more expensive the machine, the less I get to access my NAS files. Obviously something is wrong.
What's going on and how do I resolve?
Thanks everyone.
