Mac: Open File/Folder in Terminal from Finder

Why bother installing an app like Mac2Shell or others that just eat up more RAM and take up space? Just enable this preference and you can right click or create a keyboard shortcut to open files and folders in a terminal right from finder:

You can enable a Service in the Keyboard Shortcuts System Preferences to let you open a terminal window directly to a selected folder. 

Go to System Preferences » Keyboard » Keyboard Shortcuts » Services » Files and Folders » New Terminal at Folder. Or New Terminal Tab at Folder, if you want. You can create a keyboard shortcut here, too, if you're in to that kind of thing. 

Right-click on any folder and the item appears in the bottom section of the contextual menu (or use your new keyboard shortcut). Works on 'package' files, too.
