Apple Updates Platform Security Guide, Says Kernel Extensions Won't Be Supported on Future Apple Silicon Macs Thursday February 18, 2021 12:00 pm PST by Joe Rossignol Apple today shared an updated version of its Platform Security Guide [PDF], providing a comprehensive overview of the latest security advancements across iOS 14, iPadOS 14, macOS Big Sur, tvOS 14, watchOS 7, and more. apple devices mac iphone ipad watch collageapple devices mac iphone ipad watch collage For example, the guide provides security details about Safari's optional Password Monitoring feature on iOS 14 and macOS Big Sur, which automatically keeps an eye out for any saved passwords that may have been involved in a data breach. Apple also outlines the security of its new digital car keys feature on the iPhone and Apple Watch. Apple updated its "commitment to security" preamble, touting the security advantages of Apple-designed chips across the iPhone, iPad, Apple Watch, and Mac: Apple continues to push the boundaries of what's possible in security and privacy. This year Apple devices with Apple SoC's across the product lineup from Apple Watch to iPhone and iPad, and now Mac, utilize custom silicon to power not only efficient computation, but also security. Apple silicon forms the foundation for secure boot, Touch ID and Face ID, and Data Protection, as well as system integrity features never before featured on the Mac including Kernel Integrity Protection, Pointer Authentication Codes, and Fast Permission Restrictions. These integrity features help prevent common attack techniques that target memory, manipulate instructions, and use javascript on the web. They combine to help make sure that even if attacker code somehow executes, the damage it can do is dramatically reduced. New sections have been added for Macs with Apple silicon, outlining the security of the boot process, boot modes, startup disk, Rosetta 2 translation process for running Intel-based Mac apps, FileVault, Activation Lock, and more. As expected, the guide confirms that kernel extensions will not be supported on future Macs with Apple silicon (emphasis ours): In addition to enabling users to run older versions of macOS, Reduced Security is required for other actions that can put a user's system security at risk, such as introducing third-party kernel extensions (kexts). Kexts have the same privileges as the kernel, and thus any vulnerabilities in third-party kexts can lead to full operating system compromise. This is why developers are being strongly encouraged to adopt system extensions before kext support is removed from macOS for future Mac computers with Apple silicon. macOS Catalina was the last version of macOS to fully support kernel extensions. Apple says kernel extensions are no longer recommended for macOS, noting that they pose a risk to the integrity and reliability of the operating system. Starting with macOS Catalina, developers have been able to use system extensions that run in user space rather than at the kernel level. System extensions running in user space are granted only the privileges necessary to perform their specified function, which increases the stability and security of macOS, according to Apple. Apple includes a document revision history section in the Platform Security Guide with a list of all new and updated information. Apple also has a new Security Certifications and Compliance Center.

I've already been avoiding kext-based apps where possible for years.

Apple is transforming Macs into Apple Service Appliances, and allowing you to customize your OS and install stuff from other places than the App store or developer signed Apps doesn't make them any money.

Kernel extensions are out, userland drivers are in. I mean, sure, yes. But also: "Apple continues to reduce the ceiling of what's possible in macOS." If DriverKit supports enough relevant use cases, I don't see a problem. Apple is inching MacOS to full Mach, which would be awesome... killing kernel extensions before having third-party GPU support will be interesting. What is old is new again https://en.wikipedia.org/ wiki/MkLinux There won't be any third party GPU support on Apple Silicon. Why would Apple sabotage the developer and user experience ecosystem they have been painstakingly bulding? VirtualBox Made irrelevant by the new virtualization framework. Parallels Preview runs on M1 without any kernel extensions.

Before Big Sur, I used the globalSan one. With Big Sur, the writing has been clearly put on the wall and you have to jump through hoops to get it to work (plus it will kernel panic your machine if you shut down without ejecting the targets first) As this is the only third party kext I use, I reluctantly decided to migrate to using SMB shares where I could and increased my local disk space rather than continue to invest in something that clearly has limited life left. I continue to keep the somewhat forlorn hope that Apple will step in with a native solution (although I suspect it's too niche for them) That hope faded many years back for me personally. It's not going to happen. There are only prosumers in the macOS space now. Many of my contemporaries have moved to Windows/WSL and/or have Hackintoshes (including myself with an 2017 XPS.)
