I used to use version 2.3 which didn't have any problems changing id3 tags on a network drive. I now have a new computer, so I installed the latest version, 3.2.0 under OS X (latest version Yosemite) and editing id3 tags on a network drive is very problematic. I either don't see the tags at all (Tag 1 and Tag 2 empty) or I see the Tags of the files previously loaded. The old version was working without problems, I just tried it again on the same network.
Sorry, I know about this problem, and I fixed it, I just wanted to wait with a bug fix release 3.2.1 for other bugs to get discovered (or a new version of TagLib being released), but I think that I will release it soon. You can find a pre-release of the coming bug fix release on
http://sourceforge.net/projects/kid3/files/kid3/development/kid3-git20150509-Darwin.dmg
Please tell me if you find any problems with this version.
This version works. Thank you for this and for all the work you have spent on this free software.
Fixed in version 3.2.1.
