cant seem to delete files or copy/paste any files
new mac user and Im aware the commands to copy/paste files, but I just get a gong sound and files refuse to move. Same thing when I highlight a file and press the delete key, gong sound and no action taken. Is there a restriction setting I need to disable or something? Mojave upgrade, 13" air.
Also, sometimes I get the option "move to trash" in the option list, sometimes not. Why? Why wouldnt I be able to delete or move to trash anything I want?
MacBook Air 13", 10.14
