No more need to deal with the patronizing choices by Apple, or at least one less patronizing Apple design choice to deal with. Whichever procedure you decided to use, the customization of your own Mac is back in your hands. No big deal, I proceeded with the advanced procedure shown above. I managed to change the login screen wallpaper with the above procedure twice, first in macOS 10.15.2 and then in macOS 10.15.3, but after restoring a Time Machine backup this method stopped working for me. Step 16: Call it a day and restart the Mac. Step 15: Close the Library folder you opened at Step 7. Step 14: Close the Desktop & Screen Saver window. Step 13: Select once again the folder with your own wallpapers (Step 10). Step 12: Play with the images in Dynamic Desktops and Desktop Pictures, clicking on a few of them as you please. Step 10: Then, repeat Step 2 and Step 3 to select once again the newly-renamed folder.

Step 9: Since the name of the folder you selected at Step 3 has changed, the path you selected to display that folder in Desktop & Screen Saver doesn’t work anymore. Step 8: Go back to Documents or wherever you put the folder created at Step 1, and rename it with the name of your preference (this will be the final name, not going to change again). Step 7: Enter the following path /Library/Desktop Pictures and click Go. Step 6: Hit Command + Shift + G to bring up the “Go to the folder:” window.

It worked for me twice, when I first upgraded to Catalina 10.15.2 and then after installing 10.15.3, but then stopped working after I restored a Time Machine backup to go back from 10.15.2 (the.
