    You have to do the following below.

    For El Capitan and newer, the procedure is as follows:

    Disable SIP (System Integrity Protection):
    Boot into recovery mode (cmd+R)
    Select Utilities -> Terminal from the Menu Bar.
    In Terminal, input the following command: csrutil disable
    Reboot
    Boot into Safe Mode:
    Shut down the computer.
    Hold the shift key down and turn the computer on. Keep shift held until you see the login/bootloader screen.
    Input the password for a local account with administrative privileges and press Enter
    Eventually you'll be prompted for a username and password. Input the username and password of the local account to login.
    Remove the expired certificate:
    Navigate to Applications -> Utilities in finder.
    Open Keychain Access
    In the menubar, click View -> Show Expired Certificates.
    In the search box, type Entrust.
    Select the expired certificate, then right-click it and select Delete.
    Reboot the computer and boot back into Recovery mode.
    Enable SIP.
    Boot into recovery mode (cmd+R)
    Select Utilities -> Terminal from the Menu Bar.
    In Terminal, input the following command: csrutil enable
    Reboot
    After this most recent reboot, the BlueCoat agent will work again.
