#Ipsecuritas mac system extension install
Its sole purpose is to provide end user applications a way to install and uninstall system extensions. You can read through the official documentation on it here. It’s written in Objective-C and is pretty small. This is one of the new frameworks in Catalina.
Let’s take a look at some of the different subsystems. The extensions then are what communicate with the kernel. A user program calling into system services to activate or deactivate an extension and then the system itself running the extensions. With that out of the way let’s take a look at how all the different subsystems communicate with each other.Ĭonceptually there’s really two big chunks to this. There are a lot of moving parts to System Extensions and it wouldn’t be possible to cover all the internals in one post. Additionally my goal with this article is to provide an extremely high level overview. I thought it might be interesting to look at the internals of how System Extensions work.įirst a disclaimer: everything that follows is based on the Catalina betas so these details might change by the time of the final release. They have said macOS 10.15 will be the last release to fully support kexts without compromises and that in future releases of macOS Kernel Extensions with System Extension equivalents will not load at all. Apple has been attempting to wrangle in kexts for a while now and this seems to be the final nail in the coffin. It means that the code developers previously had to write in C++ can now be written in a more modern language like Swift.
From a programmers perspective I think this is even more important. It means less third party code running in kernel space which should mean more security and stability. From a security perspective I think this is a really important advancedment for macOS. One of the most exciting things announced at this years WWDC was System Extensions.
