On Apple Mac computers using Intel x86-64 processor architecture, the EFI system partition is initially left blank and unused for booting into macOS. [13] [14]However, the EFI system partition is used as a staging area for firmware updates [15] and for the Microsoft Windows bootloader for Mac computers configured to boot into a Windows partition using Boot Camp.
The most popular PowerPC emulation tools for Mac OS/Mac OS X are Microsoft's Virtual PC, and the open-source QEMU. [8] Linux dual-booting is achieved by partitioning the boot drive, installing the Yaboot bootloader onto the Linux partition, and selecting that Linux partition as the Startup Disk. This results in users being prompted to select ...
Ventoy is a free and open-source utility used for creating bootable USB media storage devices with files such as .iso, .wim, .img, .vhd(x), and .efi. Once Ventoy is installed onto a USB drive, there is no need to reformat the USB drive to add new installation files. Instead, it is enough to copy .iso, .wim, .img, .vhd(x), or .efi file(s) to the ...
Apple M2 is a series of ARM-based system on a chip (SoC) designed by Apple Inc., launched 2022 to 2023.It is part of the Apple silicon series, as a central processing unit (CPU) and graphics processing unit (GPU) for its Mac desktops and notebooks, the iPad Pro and iPad Air tablets, and the Vision Pro mixed reality headset.
PureDarwin is a project to create a bootable operating system image from Apple's released source code for Darwin. [43] Since the halt of OpenDarwin and the release of bootable images since Darwin 8.x, it has been increasingly difficult to create a full operating system as many components became closed source.
For iPhones, iPads and Apple silicon-based Macs, the boot process starts by running the device's boot ROM. On iPhones and iPads with A9 or earlier A-series processors, the boot ROM loads the Low-Level Bootloader ( LLB ), which is the stage 1 bootloader and loads iBoot; on Macs and devices with A10 or later processors, the boot ROM loads iBoot.
The Apple T2 was first released in the iMac Pro in late 2017. [10] On July 12, 2018, Apple released an updated MacBook Pro that includes the T2 chip, which among other things enables the "Hey Siri" feature. [12] [13] On November 7, 2018, Apple released the updated Mac Mini and MacBook Air models with the T2 chip. [14] [15]
The EFI System partition holds a filesystem and files used by the UEFI, while the BIOS boot partition is used in BIOS-based systems and accessed without a filesystem by holding raw binary code. The size requirements for a BIOS boot partition are quite low so it can be as small as about 30 KiB; however, as future boot loaders might require more ...
