The Get Info window lets you fix permissions so you can read and write files and folders. (I sometimes use Terminal and have to mess with file permissions behind the scenes for command-line apps.) In fact, honest to goodness, I can’t recall the last time I had to modify permissions on files created through Mac apps or by macOS. (It was removed in later releases of the app because it was no longer necessary.) Disk Utility even had a Repair Disk Permissions options to fix system settings that might have gotten out of whack. In the old days, we had to muck about with permissions all the time. Permissions are a Unix-level property attached to files (including apps) and folder that control the rights a given user or system agent has to read, write, execute, or act in other ways upon a file or folder.
MacOS says she needs to change permissions on Desktop, but I’d wager most Mac users haven’t had to wrangle with this. “filename” couldn’t be moved because you don’t have permission to access “folder”. She consistently receives the error (with various filenames and folder locations): Noelle Oliveira says her Mac isn’t letting her save files from several different programs.
