I am trying to install Dell Kace Agent for Mac and having issue for version 5.3.47657-all-dmg which I have downloaded from Dell Kace website.

Error message we get when we execute is “AMPAgent.pkg” cant be opened because it is from an unidentified developer.


I have got MacOS X 10.8

It's not officially supported until the next rev.

OS 10.8 also includes Gatekeeper which blocks installs that don't come from the AppStore or have signed publishers. You can try turning off Gatekeeper in the Security & Privacy system preferences pane and then installing the AMPAgent. Like dugullett says, however, 10.8 isn't officially supported with the current version so your results may or may not be good.

  • 10.8 will run with 5.3. It won't identify the OS and patching doesn't work. MI/scripting does.
  • Try disabling Gatekeeper. Instructions are here:
  • To disable GateKeeper from the CLI, enter this command
    spctl --master-disable

    To enable via CLI
    spctl --master-enable

    To check status via CLI
    spctl --status
