For those that are confused...
The 10.10.2 version isn't an "official" update, it's the Beta release of what will be the update at some point in the future. There are no critical updates or fixes inside this version of Yosemite. That was all done with the official 10.10.1 version, which is the one that myself and many others have reverted to.
If ANYONE has downloaded 10.10.2 it means you are part of the volunteer Beta test team that we all all signed up for prior to the release of Yosemite. You can opt out of receiving these Beta releases if you want. If you do consent to using the Beta version they warn you that you may experience system issue since we are all part of a team that has agreed to test an operating system that has been unused by more than a few hundred people.
We are here to expose flaws and issues with the software. This issue with the iPods is one of but a dozen I have come across until I reverted back to 10.10.1 since it was behaving too erratic. I use my computer for work and there were too many glitches for me to work effectively. I have done my duty and provided feedback in regards to these problems. Then I reinstalled the last official release from the App Store.
All we can do is wait for another Beta version to come around or an official 10.10.2 update that fixes the issue.
Hopefully sooner than later.
