I have an odd password thing that has recently started. I use time machine as a backup, but I also have a second external drive that I use to dump a copy of my home folder. It's also handy for when I want to copy files onto my PC. One of the folders, inside my main document folder, has started saying I must enter my password to copy it. I get a warning at the start of copying that it will be needed, then when the copying reaches that folder it waits for me to enter my password. Other than being a bit of a pain as I can't simply leave it to finish. I don't know why it does this now, or how to stop it. I've been doing the same backup on this macbook for 3 years, now the last 6 months it wants my password. I'm logged in ok, the folder in question is mine with all rights. Or could there be a folder or file inside that's not listed as mine. How do I find why it need the password when bulk copying?
