I sometimes have to tether my phone, Samsung Note 3, to my MBA and it's been about a year since I set this up. I've been wanting to change the password and it's simple as pie on the phone but on the Mac, not so much. I go into Properties>Network select the network but there seems to be no way for me to change the password. I have already changed the password on the phone but can't do it on the Mac. Does anyone know how to do this?
