Impossible to create a new folder
Hello,
I tried to create a new folder but then finder ask me by surprise for my password,
when completed,
finder refuse to create "a new empty folder" because "I do not have the necessary permission", I am the only user of this Mac, I am admin.
How can I create a new folder again ?
Thank you so much if you know how deal with this it would be very helpful :)
