Q: After transferring library to new Mac, all songs duplicated
I got a new iMac and launched iTunes and signed into my Apple account, where all my music showed up as available in iCloud.
I then transferred the iTunes library to the iMac from my old Mac notebook. Now every song is showing up twice, once with the cloud, indicating it's not on my computer but in the cloud and the dashed-outline cloud, indicating the track on my computer is waiting transfer to the cloud.
I don't know if this is just another iTunes/iCloud bug, or if I screwed up the transfer.
iMac, OS X El Capitan (10.11.3)

I think you may have "transferred" your iTunes library to the new Mac by adding just the songs from the old Mac to the new Mac's NEW iTunes library. If you did this, what you should do instead is to transfer the complete iTunes folder (including the iTunes library database) from the old Mac to the new Mac. That way, it's the same iTunes library, not a new iTunes library with your old songs.
You can use this procedure to "back up" your iTunes folder to an external drive
Back up your iTunes library by copying it to an external drive - Apple Support
To summarize, the first step is to "consolidate" all of your iTunes media files so that they are in the iTunes Media folder in the iTunes folder. (If you use the default settings, all of your iTunes media files should already be there.) The second step is to copy that iTunes folder to an external drive. The third step (with iTunes not running) is to "restore" that backed up iTunes folder onto your new Mac, to replace its existing iTunes folder. When you run iTunes, it uses that iTunes folder from old Mac. Everything looks the same, and its relationship to your iCloud Music Library is the same.
NOTE: If you know how to set up file sharing between the two Macs, you can transfer the iTunes folder directly, instead of using an external drive. Depending on network speed (and size of your iTunes folder), using an external drive may be faster.
