With the advent of Apple Silicon Macs (such as the recent Mac mini) that have the company's M1 SoC under the hood, Apple discontinued Boot Camp.

Those systems had been locked into macOS 11 Big Sur, but thanks to Arm-based virtual cloud device maker Corellium, Ubuntu Linux is now "completely usable."Īrm offers an array of licenses to its architecture that range from processor licenses, in which a chip vendor can whole hog plug modules of Arm CPU cores into a chip, to the more abstracted architecture license, which is what Apple uses to develop custom Arm64 CPUs for its own devices. Being an architecture licensee, Apple is beholden to nobody in the way that its chips implement the ISA and boot an operating system. According to Corellium, those implementation differences are what made it a bit more difficult to get running Ubuntu.

In a series of tweets, Corellium's Chief Technical Officer Chris Wade recently showed off Ubuntu running on an Apple M1-powered Mac mini, so we felt compelled to explore it a little ourselves as well. The Macintosh operating system, which itself finds its roots in NeXTSTEP system developed by Steve Jobs' other computer company, NeXT. It's based on the Mach microkernel, not GNU Linux, and has its own method for booting a system. NeXTSTEP and macOS both use Mach-O executable files, which is just a different format of executable from a WinPE executable that Windows uses on UEFI platforms, or the binary files that Arm-based Linux tends to use.

#UBUNTU ON MAC MINI INSTALL#Īnybody who's ever built a Hackintosh and had a boot problem probably had nightmares about "mach-o has a bad magic number" while trying to install the OS.Ĭorellium says that Arm-based Linux distributions have more or less settled on a format to get the system running which is nothing like Apple's Mach-O boot loader on macOS. On Intel-based Macs, the UEFI BIOS and Boot Camp worked together to form a wrapper to get other operating systems running. On Apple Silicon, that wrapper layer is gone. Mach-O is a published and open format, though, so as Corellium notes in its blog post, it was possible to get the port going.

The development team started with a Raspberry Pi 4 image and made the changes required to get the system to boot from an external drive.Īpple, being free to implement various Arm features any way it sees fit, also deviated from the de facto standards set out by other Arm PC vendors in the way additional CPU cores are brought online. Most Arm PCs rely on the firmware to make a PSCI call using additional data tables stored within the firmware itself. On M1 silicon, this is done through a memory-mapped IO register. Apple documents its behavior by publishing the Darwin source on GitHub so it was all discoverable. In newer SoCs like the M1, Apple has registers to store inter-processor interrupts, so once the OS could deal with them, all eight cores of the M1 CPU could come online.Įnabling Ubuntu's Human Interface On The M1 Still, Corellium had to get CPU cores to talk to one another, which required diving into Apple's proprietary interrupt controller.

Just getting Ubuntu to boot isn't enough to make for a usable system. Apple provides a pretty limited set of options: the Thunderbolt 4 controller, Apple's own USB 3.0 interface and Bluetooth. Apple's USB controller serves the Type-A ports on the Apple M1 Mac mini along with providing USB connectivity to the Type-C ports on all M1 systems.

On Windows PCs, Bluetooth is typically implemented over USB, even when it's built into a laptop (which can be seen by viewing Devices By Connection in Device Manager on Windows 10).
