I've been following OSX since beta and I haven't seen this tip anywhere. If you edit the com.apple.finder.plist
file in /Users/username/Library/Preferences, you can disable the preview pane in column view.
NOTE: All angle brackets are shown as square brackets in the following examples -- do not change them from angle brackets!
Open the file in TexEdit or some other text editor and scroll to the following area:
Within that [clmv] section, look for:
Change the "true" to "false" (leave the "/"!) and then relaunch (via force-quit) the Finder. Now when you open column view, you will no longer get the preview pane! I found this out simply by looking at the preferences in the terminal using the "defaults" command and testing different values.
There are a couple of other keys that do interesting things as well. Changing ColumnShowFolderArrow
to 'false' removes the right-facing arrow that lets you drill down; changing ColumnShowIcons
to 'false' removes the icons in front of the object names.
On my work machine, the entire [clmv] section was missing from finder.plist. I got a copy of the entire file from kaboom, and inserted the [clmv] key into my finder.plist file. If you're missing this section, too, read the rest of the article for a how-to on what you need to insert.
