Hi, it's a few days that my desktop is completely black, and I cannot change it.
if I chose an image, for example, and try to set it as a wallpaper, nothing happens, it stays black.
and in the top left corner of the screen it always says that the "Finder" is open but nothing is shown on the screen, I cannot close it or even actually open it....someone can help?
thanks
DO you see anything? Dock? Rest of the Finder menu bar— this would be telling.
Did you try relaunching the Finder
From >Force Quit>Finder>Relaunch
To trouble shoot further you can:
—Try a SafeBoot https://support.apple.com/en-us/HT201262
Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and test. Reboot and test as caches get rebuilt.
In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a reboot will put it back to normal mode.
This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.
—Boot into Recovery (Command R) and from the dropdown menu: Utilities> Disk Utility> run the First Aid on your Macintosh HD (and the "Macintosh HD-Data" volume as well if Catalina) If errors are found and repaired, run again until no errors reported.
