I'm kind of new to rooting, so for me this wasn't exactly one-click. For other people like me who are less experienced with terminal/rooting, here are some tips that might help. These might not ALL be required for this to work, but I'm just going through the exact steps I took for this to be successful. Some of these steps might be a no-brainer for some of you, but please be patient with the rest of us 
NOTE: I did this on a Mac with terminal, not a PC with command prompt.
Here's what a successful root should look like, if you follow the below steps.
1. After you connect your phone to your Mac, make sure the USB connection mode is set to Internet connection: Ethernet and you've enabled Debugging mode [Settings > Applications > Development > USB Debugging]. I wasn't able to enable debugging unless I had already set the USB connection mode to Ethernet.
2. Download the Android SDK. Unzip it and place it on your desktop and open up the platform-tools folder. Inside that folder is a file called "adb." Rename it to "adb.osx" (without the quotes) by just adding the .osx to the end (for those more familiar with Windows, don't worry, there is no hidden extension). Keep this Finder window open.
3. Open your spectrum_root_linux_osx folder that you've already downloaded and unzipped. Copy the entire contents of this folder into the platform-tools folder from step 2.
4. Open up terminal. Type chmod 755 and then drag and drop the run.sh file. Hit enter (this is just changing the permissions for the file, if I understand correctly).
5. Again, drag and drop the run.sh file into terminal. Just hit enter, and your phone should successfully root!
(A) If you get this error: ./adb.osx: No such file or directory, make sure that all the contents from your spectrum_root_linux_osx folder are within the platform-tools folder and you renamed the "adb" file to "adb.osx" (without the quotes).
