I have followed correctly the tutorial about flashing ubuntu on a usb stick with mac os. I can run the operating system but, obviously, nothing works. Can I install driver for trackpad and keyboard?
A Google Search for this problem revealed a kernel patch has been published for the Touchbar. However, patching the kernel used in a LiveUSB is highly problematic, and you would be better off installing Ubuntu into the USB as if you were installing to an SSD, from a different LiveUSB, then patching the kernel on the non-Live USB.
