Using Target Disk Mode on this MacBook requires a cable that supports USB 3.0 or USB 3.1, with either a USB-A or USB-C connector on one end and a USB-C connector on the other end for the MacBook. [5] With the Mac transition to Apple silicon, Apple replaced Target Disk Mode with Mac Sharing Mode.
The main application processor in T2 is a variant of the Apple A10, which is a 64-bit ARMv8.1-A based CPU. [1] It is manufactured by TSMC on their 16 nm process, just as the A10. Analysis of the die reveals a nearly identical CPU macro as the A10 which reveals a four core design for its main application processor, with two large high ...
Disk II drives.

iBoot is the stage 2 bootloader for iPhones, iPads, Apple silicon-based Macs, and the T2 chip in Intel-based Macs with such a chip. [3] [4] Compared with its predecessor, iBoot improves authentication performed in the boot chain. [2] For Intel-based Macs with a T2 chip, the boot process starts by running code on the T2 chip from the boot ROM.
Apple IIs continued to be able to boot the older DOS (even the Apple IIGS can boot the older DOS floppies) but as 3.5" floppies and hard disks became more prevalent, most users spent the bulk of their time in ProDOS. The Apple IIe, also released in 1983, was the first Apple II computer to have 64 KB of memory built in. For a while, Apple ...

Those Macintoshes include a ROM chip varying in sizes up to 4 megabytes (MB), [8] which contains both the computer code to boot the computer and to run the Mac OS operating system. The ROM-resident portion of the Mac OS is the Macintosh Toolbox and the boot-ROM part of that ROM was retroactively named Old World ROM upon the release of the New ...
