Permissions Issue/Can't move files to trash without entering password
My computer suddenly started requiring I type in my password whenever I want to move a folder or file to the Trash. It didn't ask that previously. Also, when I try to change permissions in the "Get Info" window for my external SSD I just installed, I am told I don't have the "necessary permissions." How do I correct this? Here are the warnings I get . . .
