Hi All, I bought a used Macbook Pro and noticed that there is an extra icon in "System Preferences" called "Profiles". Looks like some Enterprise IT Management settings (SSL certificate, VPN connections, energy saver settings, etc.). Do you know how to get rid of these? The '-' button is greyed out. I tried to create an El Capitan USB disk, then booted into it, then formatted the SSD (repartition), then re-installed OS X El Capitan and to my surprise, one of the options in the "new Mac startup wizard" was "Configuration Available: This Mac will be configured automatically by ______ Inc.". Do I have to create a new El Capitan USB install disk using another non-managed Mac? Maybe my El Capitan USB drive is "tainted" since I used this managed Mac to make it? Please help! Thank you.
