Can I change the name of my HOME FOLDER
I have recently purchased a 21.5" iMac 2009 running OS Sierra for the express purpose as I needed access to a working copy of GarageBand for my son's school project.The previous owner {whom I know well} removed all his personal data but left genetic user admin User Account settings including his admin password to help me get around any issues that we may encounter,which hasn't happened I might add. Can I now rename his Home Folder to something more appropriate and if so also change the old password. Thank you for any assistance.
