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. It's based on the Mach microkernel, not GNU Linux, and has its own method for booting a system. The Macintosh operating system, which itself finds its roots in NeXTSTEP system developed by Steve Jobs' other computer company, NeXT. 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. According to Corellium, those implementation differences are what made it a bit more difficult to get running Ubuntu. Being an architecture licensee, Apple is beholden to nobody in the way that its chips implement the ISA and boot an operating system. 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.
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.
Apple even included a Windows preparation tool, Boot Camp, on all of its systems with Intel Core processors.
One of the more pragmatic aspects of Intel-powered Macs was their ability to run alternative operating systems, including Windows and Linux, without much effort at all.
