there are times when your organization/company locks down your computer and you have to install software. Here is how to gain access to install software.
Obviously you will need to have root access. Most of the time, if you are configured as an administrator on the Mac, you will be able to gain root.
1. Open up Terminal
2. Run this command $ sudo spctl –master-disable
spctl is the Mac’s SecAssessment System Policy Security.
What we are doing is Disabling the assessment subsystem altogether. Operations that would be denied by system policy will be allowed to proceed; assessment APIs always report success. Requires root access.
