I downloaded the bullseye alpha 3 installer, firmware-bullseye-DI-alpha3-amd64-DVD-1.iso MD5: a1e967406869b1b0b64a1b808d39dd1a
My computer is a Macbook Air 2020 I shrank the Apple partition, disabled secure boot and I was able to boot with the Debian installer. The keyboard, mouse, wifi and sound don't work in the installer or in the installed system. I had to use a USB keyboard and mouse connected with a USB-C dock. During install, the grub install failed. I booted with the altlinux.org resuce image, entered the Debian partition with chroot and used apt to install the Debian refind boot manager package. refind is working but I have to press Option every time I turn on the machine, otherwise it always goes to Mac. Can anybody tell me how to make the builtin keyboard, trackpad, wifi and sound work again? -- Regards Himani Agarwal[image: https://s3.amazonaws.com/htmlsig-assets/spacer.gif]
