proper way to change admin accounts to standard
I'm looking for the proper way to change some of the administrative accounts on macs I support from Administrative to Standard.
the systems in question have at least two adminsitive accounts and I will only be performing this on one of those accounts.
currently there is data for the users (images, music, etc.) in their home accounts.
Is this simply a question of going in as an admin on one account, selecting the other account and turning off the "allow user to administrate this computer" checkbox or is there more to it, like creating entirely new accounts?
this is also predominantly a 10.9 question but I have a system running 10.10 that also needs to be addressed.
Mac Pro, OS X El Capitan (10.11.2), Dual Xeon 2.4, 64 GB RAM
