On June 6, 2022, at WWDC 2022, Apple announced an updated MacBook Air based on the M2 system on a chip. [20] It incorporates several design elements from the M1 Pro and M1 Max MacBook Pro models, such as a flat, slab-shaped design, full-sized function keys, and a Liquid Retina display with rounded corners and a notch for a 1080p webcam.
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.
A MacBook Air (15-inch, M2, 2023) running macOS Ventura. On June 6, 2022, during the 2022 Worldwide Developers Conference (WWDC), Apple announced their second-generation processor, called M2, with an improved performance versus the previous M1 processor. The first computer to receive this new chip was a radically redesigned MacBook Air.
The Apple MagSafe power adapter's 1-Wire communication chip is located inside the MagSafe connector itself; the cable does not carry the data line to the power adapter enclosure. [18] The maximum voltage supplied is as follows: 14.5 V DC for the 45 W units supplied with MacBook Air; 16.5 V DC for the 60 W units supplied with MacBook and 13 ...
Some computer designs have used non-button cell batteries, such as the cylindrical "1/2 AA" used in the Power Mac G4 as well as some older IBM PC compatibles, or a 3-cell nickel–cadmium (Ni–Cd) CMOS battery that looks like a "barrel" (common in Amiga and older IBM PC compatibles), which serves the same purpose. These motherboards often have ...
CMOS inverter (a NOT logic gate). Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss ", / s iː m ɑː s /, /-ɒ s /) is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions.

The M4 Pro features an up to 14-core CPU, with 10 performance cores and 4 efficiency cores, along with up to a 20-core GPU that Apple claims is twice as powerful as that in the M4 when used in the corresponding MacBook Pro. The M4 Pro is available with up to 64GB unified memory (Mac Mini) with a theoretical maximum bandwidth of 273GB/sec. [11]
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]
