How to Add a Dock Shortcut to Any MacOS Preference Pane
If you frequently access the same System Preferences pane on your Mac, you can add a shortcut right to the dock. Here’s how:
All preference panes are located by default in / System / Library / PreferencePanes / and you can easily reach that folder in Finder by typing Shift-Command-G to open the Go To Folder dialog and typing (or pasting) the above path into field. When you click Go, you will see a list of all the preference panels that you might otherwise find in System Preferences. Drag one into your Dock (on the right, with files and folders) and you ‘re done! – shortcut on the settings panel.
If you want to add shortcuts to third-party panels, they are located in your custom library folder: ~ / Library / PreferencePanes , so just follow the instructions above and replace that path in the Finder Go To Folder dialog.
If you’ve been using a Mac for a while, you probably know that there are several ways to do anything, including accessing your system preferences. Go to the TidBITS, to see the full details of all the bizarre ways in which you can pick up your system settings.
