This link describes the process: https://null-byte.wonderhowto.com/how-to/hacking-macos-configure-backdoor-anyones-macbook-0184637/<p>What I don't understand and why I'm asking this is, why isn't this patched? Should this be patched? What possible value or reason is there for it to be so easy to hack a mac not using filevault?<p>It appears that a firmware password prevents this problem. If this is so, then why isn't a firmware password more widely known about and encouraged?
This isn't really a hack, though.<p>It's more like "How to configure standard system tools to do stuff you want."<p>Potentially any modern O.S. will allow what is described in the article, if your privileges are root/admin.
