The driver provides support for Human Interface Devices (HID) on Serial Peripheral Interface (SPI) buses on Apple Intel Macs produced in 2015-2018. The driver appears to work more stable after installation of Darwin OSI in acpi(4) driver. To install Darwin OSI insert following lines into /boot/loader.conf: hw.acpi.install_interface="Darwin" hw.acpi.remove_interface="Windows 2009, Windows 2012" Reviewed by: wulf Differential revision: https://reviews.freebsd.org/D39863
