I’ve just updated my Parents Macbook Air 13.3" Early 2015 from High Sierra to Catalina and I’ve noticed that in ‘Desktop Pictures’ in ‘System Preferences’ there are duplicates of ‘Mojave Day’ and ‘Mojave Night’. These appear at the very end i.e. after ‘Abstract Shapes Neutral’. Obviously the ones that are numbers 10 & 11 are the correct ones. I’ve also noticed the duplicates are framed slightly differently in that they show slightly less to the left, but slightly more to the right. Does anyone know how to get rid of these duplicates?
Here’s are two screenshots - the first showing the correct 'Mojave Day & Mojave Night, the second showing the duplicates:
Another thing I noticed about the Desktop Pictures is that if I do a count I get 77, yet if I go to the ‘Desktop Pictures’ folder in the System Library and I do a count I only get 33! So where are the other 44?
