Root LG G3 D855 5.0 Lollipop with a Mac I have been trying to root my LG G3 (D855) with Android 5.0 using my Mac Book Pro and so far I haven't been able to find a working method. 

I followed this guide, but it seems that the combination of Android Version + Hardware Version of my phone isn't compatible with the vulnerability.

I also tried guide-root-lg-firmwares-kitkat-lollipop One Click root option, but it requires Windows...

Do you guys have any suggestions? I even tried to downgrade to Android 4.2.2, but I couldn't find a Mac guide for that either....

Any help is appreciate. Thanks!
You don't need to Downgrade the version of the phone's firmware,You just need an working method to root your device, Since all the "One-Click-Script" ways doesn't work for you, We'll go the Classic way, Just follow this guide,

Download the ROOT package from HERE


  
  Enable ADB debugging
  
  
  Go to Settings > About Phone > Software Information and tap build  number until you are presented with "You are now a developer". 
  Back to Settings screen.  
  In Developer Options, enable USB Debugging.
  
  Insert the USB cable
  Send the required files to the device using this command
  
  
  adb.exe push busybox /data/local/tmp &amp;&amp; adb.exe push
  UPDATE-SuperSU-v2.46.zip /data/local/tmp
  
  
  Go to Download Mode
  
  
  Disconnect the USB cable.
  Power off the device.
  Hold volume up and insert the USB cable.
  
  Find which COM port your device is connected
  
  
  Run ports.bat
  From the output see what ports your phone connected to
  
  
  
  
  
  Run the root installer script
  
  
  Send_Command.exe \.\COMx &lt; root
  Send_Command.exe \.\COMx &lt; reboot
  Change the COMx with the correct port number of the DIAG port.
  and the output should be like this 
  
  


I'm not a MAC guy, So i don't know for sure if you can do that on your MBP, But i know that you can use VirtualBox to install Windows inside your MBP as described HERE.
