I just set it up on my Mac to see how difficult it is, and it's not too bad. I'm gonna write a little short guide here that you should be able to follow, and hopefully it works. Keep in mind this assumes that you download deemix to the folder Downloads in your user folder.

• Download deemix from here

• Download Python from here (don't worry about versions or anything, just click the yellow "Download Python" button near the top)

• Go into your downloads folder and unzip the folder with Archive Utility. It should be a folder named deemix.

• Open up a terminal and enter the following

  cd downloads/deemix

• and then

  python3 -m pip install -r requirements.txt --user

• you should see a bunch of text and progress bars scrolling past, wait until all of that stops. Once it stops and lets you type again, put in

  python3 server.py

• Minimize the terminal, open up a browser, and navigate to http://127.0.0.1:9666

And you should have deemix! You'll have to do the stuff like adding your arl just like in deezloader remix. To open it again, you can open a terminal and type cd /downloads/deemix then python3 server.py

I'm going to try a script too for running it after install without commands, but I'm not great with macs, lol
