How do I install Dji asssitant on my mac?

Download it from the DJI website. Open it from your downloads folder on your Mac. It should come up with a box on screen. Select and hold the left icon and slide it across to apps ( I think ). It should then be available in your finder and there you go. Not the exact DS solution but that's roughly what I did on my Mac mini and it works fine. Failing this just go to YouTube and there's tutorials galore to search through.

Really? You need to ask this? You install it like you would any other program.

If you can't find it after installing,  search for "assistant" or look in mission  control for it

Here's the web for download DJI Assistant 2. Hope you can install it finally. https://www.dji.com/mavic/info#downloads
