![]() ![]() While this unlocks a lot of freedom for developers, it also creates risks: Even a minor bug could freeze or panic the system.īeyond the stability challenges that kernel extensions present developers while creating apps, the power of kexts also creates some security concerns. ![]() While kexts have given developers the freedom to build powerful, complex functions, it also presents them with challenges in terms of development, security, and stability.īecause actions taken by kernel extensions occur within the kernel, they’re prioritized over every other function in the system. Virtualization applications (such as Parallels Desktop or VMWare Fusion), virtual drive services (such as Box and Google Drive), and other software have long used kexts to integrate their code deeply into the Mac.īut that access has some downsides. By giving developers these kernel privileges, kexts can help those developers create some very powerful apps. ![]() Kernel extensions (or kexts) let developers load code directly into the macOS kernel. Here’s what admins should know about it and how they can use that knowledge to make life smoother for themselves and their users. That transition is still playing out, even now. Specifically, the company said that kernel extensions (kexts) would be deprecated in favor of system extensions. Back in 2019, at its Worldwide Developers Conference (WWDC), Apple announced some major changes to the way software developers would be able to interact with macOS. ![]()
