Mac profile installation failed - unexpected error MDMResponseStatus:500

When trying to enroll a Mac into Securly MDM, you may receive the following error message when installing your profile:

Mac profile installation failed.  The profile...could not be installed due to an unexpected error. <MDMResponseStatus:500> 

This can be caused if the device can't reach the enrollment server.  This is usually caused by a web filter agent or some other type of Internet security agent or app on the computer.  By temporarily removing the filter agent, the MDM profile should be installed. The filter can then be installed or enabled again.
