$ cp pywal/pywal/sequences.py ~/Library/Python/3.9/lib/python/site-packages/pywal/sequences.py Library/Python/3.9/lib/python/site-packages/pywal/sequences.py

$ find $HOME -type f -name 'sequences.py' $ find /usr/local -type f -name 'sequences.py' My full installation went something like this: $ pip3 install -user pywal If you think it would be easier to install it from PyPI and patch the file, that is also an option - just run pip3 install pywal, and then find the location of sequences.py in your site-packages/pywal directory (mine happened to be at ~/Library/Python/3.9/lib/python/site-packages/pywal/sequences.py), and then just copy sequences.py from the master branch to your site-packages, and you are good to go. I would suggest cloning it from the git repo and building it from source, as there is an issue with the current version on PyPI that does not include a fix to show the cursor location in iTerm2. Not only will it change the desktop image for all desktops with a single command, but it also has the ability to set your Terminal colors to a theme to match your desktop background (as long as you are using iTerm2 and not Terminal.app). I have always used pywal on all of my Linux machines, and I just wanted to see if it would also work on MacOS, and indeed it does.

This might not be the answer you are looking for, but it is by far my favorite (requires Python3): This is a lot easier than closing and reopening the desktop preferences on each desktop, and way easier than deleting and recreating all desktops (for me, at least). (If you have multiple monitors, then each monitor will have it's own Desktop window, named something like 'Secondary Desktop'.) The window will update to reflect the new desktop in focus and I can switch that desktop's image to whatever I want it to be. Then, open Mission Control (on my machine, I launch Mission Control with the 'Swipe up with three fingers' gesture) and drag & drop the Desktop & Screen Saver window onto the next desktop. > Desktop & Screen Saver ), then change the wallpaper on the current desktop. Instead, you can open up your Desktop preferences ( > System Preferences. If, like me, you have your additional desktops arranged just how you like them, then the thought of deleting and recreating them just to change the wallpaper would be like recommending that I demolish my house so that I can repaint the walls. Another option until Apple gives us a better one:
