Can I back up the saved WiFi passwords on my Mac? Too frequently my Mac connects to WiFi but can’t access the Internet on cafes (my iPhone works properly). It has been tormenting me for over a year and I tried everything I found on the web but still could not resolve it. So I finally want to reset the WiFi settings.

However, if I reset the WiFi settings on my Mac, it erases all the saved WiFi passwords I connected on cafes, which have more than 500. It is not what I want to do to ask each password again whenever I enter the cafes again, so I rather want to back it up and restore whenever I want.

Is this possible?
All WiFi passwords are stored in Keychain.
So you need to make a backup of the keychain folder.
