On Macs, a feature known as Safe Sleep saves the contents of volatile memory to the system hard disk each time the Mac enters Sleep mode. The Mac can instantaneously wake from sleep mode if power to the RAM has not been lost. However, if the power supply was interrupted, such as when removing batteries without an AC power connection, the Mac ...
Sleep mode (or suspend to RAM) is a low power mode for electronic devices such as computers, televisions, and remote controlled devices. These modes save significantly on electrical consumption compared to leaving a device fully on and, upon resume, allow the user to avoid having to reissue instructions or to wait for a machine to boot .

(The latter is always the case on single-processor systems.) [8]
Sometimes, the loop device is erroneously referred to as loopback device, but this term is reserved for a networking device in operating systems. The concept of the loop device is distinct. In BSD-derived systems, such as NetBSD and OpenBSD , the loop device is called "virtual node device" or "vnd", and generally located at /dev/vnd0 , /dev ...
The MacBook is thinner than its predecessor, the iBook G4, but it is wider than the 12-inch model, and has a widescreen display.

As part of the Mac transition to Intel processors, Apple released a 13-inch laptop simply named "MacBook", as a successor to the PowerPC-based iBook series of laptops. . During its existence, it was the most affordable Mac, serving as the entry-level laptop that was less expensive than the rest of the Mac laptop lineup (the MacBook Pro portable workstation, and later the MacBook Air ultra-port
All models use Apple-designed M series systems on a chip. The first MacBook Pro with Apple silicon, based on the Apple M1, was released in November 2020. The 14-inch and 16-inch MacBook Pros were released on October 26, 2021. Powered by either M1 Pro or M1 Max chips, they are the first to be available only with an Apple silicon system on a chip ...
