When in Finder Column view its handy to have the default set a bit larger. At the bottom of the window hold the OPTION key while dragging the || handle to the desired size. Right click || to Right Size all Columns Individually (which would be a nice default if I could figure that out).
At the bottom of the Finder window
Lightroom incorrectly reports that there is no Trash folder (or ability to restore deleted images). Believe it or not, all you have to do is within Finder, create a folder on the Root of your image library (where the images are stored, not the Catalogue if they are different) and delete it within Finder. Seems to fix problem.
