How do I update my TD-H3 using a MacBook. 

Do I use Chirp, OdMaster or the Tidradio Website? 

What's the steps/process?

Any links/download links & tips would be appreciated. 

Thanks!!

If you’re familiar with the command line, this one worked for me TDH3Flash. You can get the original firmware from TIDradio’s website and use this tool to load it into the radio.
