A few questions have arisen with the new browse dialog in OS X systems. The primary issues raised have been an inability to find desired folders, mounted drives and/or network drives. The new dialog has a single drop down folder at the top that generally defaults to the user’s home folder, showing the folders for things like Applications, Documents, Downloads and Pictures. To browse to USB or network drives, use the drop down list to select the hard drive, which will be the last item on the list (it may be labeled as Mac HD, boot, Hard Disk, etc.). In this example, you would select “boot”
Next, double-click on the Volumes folder at the bottom.
All the available drives/devices should all be listed, including any mounted drives or networked drives.
To get back to the desired home folder to get to Pictures, etc. from the hard drive use the top drop down list and select/open Users in the folder list, then the user name needed.
