Linux For M1 Macs? First Alpha Release Announced for Asahi Linux

"Asahi Linux aims to bring you a polished Linux experience on Apple Silicon Macs," explains the project's web site. And now that first Asahi Linux alpha release is out - ready for testing on M1, M1 Pro, and M1 Max machines (except Mac Studio):We're really excited to finally take this step and start bringing Linux on Apple Silicon to everyone. This is only the beginning, and things will move even more quickly going forward! Keep in mind that this is still a very early, alpha release. It is intended for developers and power users; if you decide to install it, we hope you will be able to help us out by filing detailed bug reports and helping debug issues. That said, we welcome everyone to give it a try - just expect things to be a bit rough.... Asahi Linux is developed by a group of volunteers, and led by marcan as his primary job. You can support him directly via Patreon and GitHub Sponsors.... Can I dual-boot macOS and Linux? Yes! In fact, we expect you to do that, and the installer doesn't support replacing macOS at this point. This is because we have no mechanism for updating system firmware from Linux yet, and until we do it makes sense to keep a macOS install lying around for that. You can have as many macOS and Linux installs as you want, and they will all play nicely and show up in Apple's boot picker. Each Linux install acts as a self-contained OS and should not interfere with the others. Note that keeping a macOS install around does mean you lose ~70GB of disk space (in order to allow for updates, since the macOS updater is quite inefficient). In the future we expect to have a mechanism for firmware updates from Linux and better integration, at which point we'll be comfortable recommending Linux-only setups.... Is this just Arch Linux ARM? Pretty much! Most of our work is in the kernel and a few core support packages, and we rely on Linux's excellent existing ARM64 support. The Asahi Linux reference distro images are based off of Arch Linux ARM and simply add our own package repository, which only adds a few packages. You can freely convert between Arch Linux ARM and Asahi Linux by adding or removing this repository and the relevant packages, although vanilla Arch Linux ARM kernels will not boot on these machines at this time. The project's home page adds that "All contributors are welcome, of any skill level!" "Doing this requires a tremendous amount of work, as Apple Silicon is an entirely undocumented platform," the team explains. "In particular, we will be reverse engineering the Apple GPU architecture and developing an open-source driver for it." But they're already documenting the Apple Silicon platform on their GitHub wiki.We will eventually release a remix of Arch Linux ARM, packaged for installation by end-users, as a distribution of the same name. The majority of the work resides in hardware support, drivers, and tools, and it will be upstreamed to the relevant projects.... Apple allows booting unsigned/custom kernels on Apple Silicon Macs without a jailbreak! This isn't a hack or an omission, but an actual feature that Apple built into these devices. That means that, unlike iOS devices, Apple does not intend to lock down what OS you can use on Macs (though they probably won't help with the development). As long as no code is taken from macOS to build the Linux support, the result is completely legal to distribute and for end-users to use, as it would not be a derivative work of macOS. An interesting observataion from Slashdot reader mrwireless: It once again seems Apple is informally supportive of these efforts, as the recent release of OS Monterey 12.3 makes the process even simpler. As Twitter user Matthew Garrett writes: "People who hate UEFI should read https://github.com/AsahiLinux/... - Apple made deliberate design choices that allow third party OSes to run on M1 hardware without compromising security, and with much less closed code than on basically any modern x86."
