How to install Tor from source on OS X
Tor Browser

Have you considered using Tor Browser instead of tor?


  The Tor Browser lets you use Tor on Windows, Mac OS X, or Linux without needing to install any software. It can run off a USB flash drive, comes with a pre-configured web browser to protect your anonymity, and is self-contained (portable).


Still need tor? Use brew

You can use the homebrew project to install tor on your Mac.


Follow the instructions on homebrew to install the brew command:


Launch Terminal.app
Paste in the one line command from brew.sh: 

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"


Run the following command to install tor and any dependencies:

brew install tor



Easy Removal

If you decide later to remove tor, you can use the command:

brew uninstall tor


Alternatively, you can probably use MacPorts.
