Hooks with mandatory access control framework
Hello, I've come across information regarding macOS endpoint protection software: It seems Apple no longer allows them to create kernel extensions. It seems that endpoint software should now function with MACF by implementing hooks from userland. Does this mean the Endpoint Security Framework will soon become deprecated? I'm currently searching for a sample source code for MACF hooks, but I haven't found anything in the Apple developer documentation. Thanks

Where does macOS store file open intent paths ? (TCC)
Hello, It is possible to restrict Documents folder access with TCC. But when an applications shows a standard "file open" dialog, it is possible to access this directory to open a file. macOS allows file access in this case because it is an intentional action from user. So i suppose there is a kind of whitelist for all files path opened through "file open" dialog. I would like to know how i can access this whitelist and how i can remove entries. Thanks

Filevault encryption key on macOS
Hello, It is possible to encrypt a mac's hard-drive with Filevault. All home user folders are encrypted with the same encryption key. (This is the same encryption key for the whole hard-drive). This encryption key is encrypted with user password. But i don't understand how it works when there are multiple user accounts. Maybe there is a table: The same encryption key is stored several times (one per user account) ? Is there a way for a user to read the filevault encryption key ? Thanks
