Mac: If you frequently access the same System Preferences pane on your Mac, you can add a shortcut directly to your Dock. Here’s how.
All of the default preference panes are located in /System/Library/PreferencePanes/, and you can get to that folder easily in Finder by typing Shift-Command-G to open the Go To Folder dialog and entering (or pasting) the above path into the field.
When you hit “Go”, you’ll see a list of all of the preference panes you’d otherwise find in System Preferences. Drag one to your Dock (on the right side, with files and folders), and presto! — a Preference Pane shortcut.
If you want to add shortcuts for third-party panes, those are found in your User Library folder: ~/Library/PreferencePanes, so just follow the above instructions and substitute that path in the Finder Go To Folder dialog.
If you’ve been using a Mac for a while, you probably know that there’s more than one way to do anything — including accessing System Preferences. Head over to TidBITS to see the full rundown of all the quirky ways you can pull up your system’s settings.
