I once took my personal iMac to work and enterprise policy settings have been downloaded unto it. I am trying to download the OS X EL Capitan beta and I keep getting the software update policy on the mac will not allow it. I would like to disable this setting as it is my private mac, but I have no idea how to or where to do it.
Administrators use Configuration Profiles in Mac OS X to standardize settings & behaviour.
A configuration profile can contain settings for configuring a user’s Mail account, Wi-Fi settings, VPN settings, and more.
To view installed configuration profiles
- Choose Apple menu > System Preferences, and then click Profiles.
- View the list of profiles installed & their details as shown
- To remove the profiles, select the it & click (-)
As you said this is your personal computer. Assuming you didn't do anything of this sort, you should be good to remove all the profiles listed & restart the computer to bring the changes in effect
