Systempal extension mac5/19/2023 The alert may inform you that it will damage your computer and has been blocked.The alert may ask you to contact the developer for support because the extension needs to be updated or will be incompatible with a future version of macOS.The alert may ask you to open Security & Privacy preferences to allow the extension.*Kernel extension deprecation policies are not enforced when SIP is disabled or if a kernel extension is approved through a MDM profile.You may see an alert on your Mac that says that a program loaded or tried to load a system extension signed by the developer of that extension.Send us your API enhancement requests or bug reports through Feedback Assistant. Your feedback is valuable and helps inform the direction of our system extension development. To deploy drivers built with DriverKit or use the EndpointSecurity API, you’ll need an entitlement from Apple. Clients should use SCISControllerDriverKit instead. IOSCSIParallelFamilyĪll KPIs in IOSCSIParallelFamily are deprecated in macOS Monterey 12.3. Bluetooth "Classic" is no longer supported. Bluetooth LE clients should use CoreBluetooth instead. IOBluetoothHIDDriverĪll KPIs in IOBluetoothHIDDriver are deprecated in macOS Monterey 12.3. Clients should use AudioDriverKit instead. IOAudioFamilyĪll KPIs in IOAudioFamily are deprecated in macOS Monterey 12.3. Clients of IONetworkingFamily KPIs should use NetworkingDriverKit instead. PCI KPIs have alternatives in PCIDriverKit. The combination of using IONetworkingFamily KPIs as well as IOPCIFamily KPIs is deprecated. DriverKit also has mechanisms for communication channels. USB KPIs have alternatives in USBDriverKit or consider IOUSBHost framework. USB vendor-specific IPCĪny kernel extension using USB KPI (IOUSBHostFamily or IOUSBFamily) that doesn't tie into the IO Family subsystem and uses IOUserClient, or subclasses, for IPC is unsupported in macOS Big Sur. Clients of IOSerialFamily KPIs should use SerialDriverKit or USBSerialDriverKit instead. USB KPIs have alternatives in USBDriverKit. The combination of using any IOSerialFamily KPI as well as any USB KPI (IOUSBHostFamily or IOUSBFamily) is unsupported in macOS Big Sur. The combination of using IONetworkingFamily KPIs as well as any USB KPI (IOUSBHostFamily or IOUSBFamily) is unsupported in macOS Big Sur. Clients should move to IOUSBHostFamily or USBDriverKit, where appropriate and as outlined below. IOUSBFamilyĪll KPIs in IOUSBFamily are unsupported in macOS Big Sur. The following Network Filter KPIs are unsupported in macOS Big Sur:Īll KPIs in IOHIDFamily are unsupported in macOS Big Sur. Clients should use NetworkExtension instead. The following Socket KPIs continue to be deprecated in macOS Big Sur. Clients should use EndpointSecurity instead. The following KPIs are unsupported in macOS Big Sur. Any kernel extension using an unsupported KPI will not load.* KAUTH Software that supports a broad range of macOS versions should continue to use kernel extensions for older versions and run system extensions where supported.īelow is a list of unsupported KPIs as of macOS Big Sur. If your software uses new system extensions and legacy kernel extensions, you can distribute to supported operating systems. If your software uses deprecated and supported KPIs for older versions of macOS, you’ll need to factor out deprecated components into a stand-alone system extension. Transitioning your kernel extensionsĬertain kernel extensions are unsupported on macOS Big Sur. Starting with macOS Big Sur, macOS releases no longer load kernel extensions that use deprecated kernel programming interfaces (KPIs) by default. As part of our ongoing effort to modernize the platform, improve security and reliability, and enable more user-friendly distribution methods, kernel extensions have been deprecated. System extensions on macOS Catalina 10.15 or later allow software, such as network extensions and endpoint security solutions, to extend the functionality of macOS without requiring kernel-level access.
