If you edit the com.apple.dock.plist in your preferences folder, it will allow you to turn on many features (such as those which can be accessed using GUI appls like TinkerTool). But it will also let you turn on the QuitFinder boolean. This will add a quit option for the finder. I don't know who this would be of much use to, mabye those with only 128 RAM would find it useful in some processor-intense apps.
[NOTE: On my machine, editing the dock.plist file in either the terminal or the dev tools' property list editor, I do not see this boolean! I have no idea why, and reidab sent me a screenshot showing that his version does have it ... odd! I could just add it, I suppose...]
If you have a folder in your Finder toolbar, hold option and click to open that folder in a new window and close the old window. Clicking without option simply opens that folder in the existing window. Strangely, it seems to switch to icon view regardless of the view mode from which you click [editor - not on my machine; it seems random!]. If you command-click the folder, it opens in a new window without closing the old one.
Application icons that have been added to the toolbar can be used to switch to the given app, saving you a bit of time and mousing down to the dock to switch. Drag-and-drop apps (such as Stuffit Expander) can have things dropped on them on the toolbar.
If you hold down the Option (Alt) key while clicking the yellow 'minimize' button of a document window, all of that application's open document windows will minimize into the Dock, and each will have its own icon.
Holding down Shift and Option makes all of the app's windows dock, but very slowly. This is the demo slow genie effect for multiple windows.
Unfortunately, and this is a bug or an egregious oversight, when you hold down Option and click one of the app's minimized windows, all of the docked windows do not restore.
By the way, shouldn't the verb for minimizing be, not "to minimize," but "to dock"? Dock your window.... just a thought.
A hierarchical menu will not work for an alias to a folder in a Dock folder if it is created by the contextual menu 'Make alias' command. This must be done [for now] from the command line:
ln -s [path/to/linked/directory] [name of Alias]
-- creating a seamless menu to that aliased folder within a pop-up menu from the dock:)
A related tip: Find the folder you wish to alias in the finder window and drag it onto the terminal window to copy the full path.
I've placed my Apps and Home on the Dock with symbolically linked folders to my Classic Documents and Apps folders (which is much tidier than intermingling and copying over to my OS X native partitions.) One could also create a "Favorites" pop-up in the same way ...
I know credit is due somewhere else, but I can't find the reference anywhere - so I felt compelled to share. Hope this makes your navigation that much better, easier.
Saw this one somewhere today, and it's a good one. The Finder doesn't seem to remember that I prefer column view with about seven columns showing. I set my window that way, navigate around, close it, open a new one, and I get icon view again ... a little frustrating! Turns out there is a way to get it to remember the settings.
Close all your finder windows, open a new window, set it the way you like it (column view, icon view, width, height, whatever). Now close that window before you do anything in it. From now on, all your new Finder windows will open with those characteristics. I'm not sure whether this is a bug or a feature, as it sometimes seems inconsistent about remembering.
In some instances, your OS X disks may display all your applications as folders. When you double-click them, they open like folders to show the package contents, instead of launching. This usually happens after after a crash. There's a relatively simple fix, which you can see if you read the rest of this article.
The solution is courtesy of Apple's Tech Info Library (TIL), which you can find here:
This site hosts all sorts of interesting material (I've added it to the links section); just change the drop down to "Operating Systems" and type (without the quotes) "OS and X" to find relevant articles.
I put the 'Internet Connect' icon in my dock for easy access. But when I reboot its always gone and I have to put it in again. Am I doing something wrong? Do I need to do something to save the dock's state?
Editor's note: 'cashd' provides the answer in the comments:
'When you open an application, you see it's icon in the dock. When you close the window for that app, you still see it in the dock. When you quit the application, you no longer see it in the dock.
If you want an application's icon to stay in the dock, even after you have quit it, you must click and hold on the application's icon, until a menu appears. Then you just need to select, "Keep in Dock" from that menu.'
You probably know you can customize the toolbar by selecting View...Customize Toolbar..., but did you also know you can also drag applications directly onto it? I added the Terminal.app to my toolbar. Very handy.
Some people have reported left-over pieces of dock 'poofs' on their desktop. These bits remain through resolution and color changes, and seem indefeatable until you logout and login again.
There's an easier way to get rid of them -- just launch ProcessViewer (in the Utilities folder), and look for the "Dock" process. Highlight it and then select the Quit Process menu item. The dock will quit, the 'poof parts' will vanish, and the dock will then restart.
