Changing iMac wallpaper
I have the 2021 iMac M1 chip I have changed my wallpaper to my logo multiple times and it will stay for the day but as soon as I shut my iMac down for the night and turn it back on the next day it changes my wallpaper back to the default. Does anyone know why it keeps doing this or how to prevent it??
