I've been dealing with an issue for a very long time, I feel like it used to be a problem randomly, but at least for the last few months it's persistent. The Finder no longer lists mounted Disk Images (
.dmg files) in the sidebar. Not for DMGs, nor external hard drives / external media.
The volumes are listed in Disk Utility, and I have resorted to using that to gracefully unmount the disk image. When a volume is mounted, it is possible to access it by it's
/Volumes/<Volume Name> path.
In this screenshot you see Finder's Sidebar preferences. You can see that I have a DMG for Clementine open, and Disk Utility confirms that. But the volume isn't showing up on the sidebar. You can also see that the Devices list is expanded, listing my built in volume.
I've done some light searching of options to see if it could be controlled by a plist
defaults setting, but I haven't found anything yet.
Why aren't mounted volumes showing up on the sidebar? How can I restore them in the list?
This problem began under Mavericks, and has persisted in Yosemite.
