Several people have reported that folders that they’ve put in the Favorites section of the sidebar in Finder windows just disappear, and have thought that either Default Folder X or Jettison was at fault. I’ve confirmed with Apple that this is a known bug in Mac OS 10.9.2. It’s not caused by Default Folder X, Jettison or any other 3rd party application. It’s an issue that Apple needs to fix in OS X.
Here’s a more complete description of the problem:
If I drag a folder to the Finder sidebar to add it as a Favorite, then later eject the disk containing the folder, the Finder deletes the folder from the sidebar. It doesn’t return when I remount the disk.
Steps to Reproduce:
- Plug in an external drive (I used a FW800 drive, but apparently any old disk will do).
- Open a Finder window, navigate to the external drive and then drag a folder from the drive to the Favorites list in the Finder window’s sidebar.
- Eject the external drive.
- Run Disk Utility and remount the external drive.
I would expect the folder to stay in the Favorites list in the sidebar, regardless of the availability of the disk. If I click on it it should ask for the disk or try to remount it automatically. Failing this, if the folder is going to be hidden in the sidebar because the disk is unavailable, it should reappear when the disk is available again.
The folder is removed from the Favorites list in the sidebar, never to return.
