1. MacOS is Apple's proprietary desktop and laptop operating system (OS).
2. Every Mac is run by a proprietary graphical operating system.
3. The operating system (OS) works with the hardware of a computer to assign resources such as memory, processing power, and file storage to carry out tasks.
4. MacOS performs quickly and responsively since it is tailored for certain Apple hardware.
5. About once per year, Apple releases a new version of macOS.
6. It was released to power Macintosh personal computers (PCs) in 1984.
7. Graphical user interfaces (GUIs) gained tremendous popularity thanks in large part to MacOS.
8. Microsoft abandoned its prior user input methods in favour of GUIs for Windows OSes as a result of its GUIs' popularity.
There are a few privacy issues with macOS that deserve your attention. These don't apply to Apple's other programmes and services, just the operating system itself.
It is possible to set up brand-new Apple silicon devices without an internet connection. The Activation Lock database of lost or stolen devices must be accessed via an internet connection for your Mac to be recovered or reset.
It will appear here each time an application asks for a permission. You can choose which programmes receive a specific authorization and which ones do not.
Numerous tools and functionalities that MacOS offers let users perform a variety of tasks. They consist of the following:
•Features in Media. Utilising applications like Music, TV, Podcasts, Books, and Photos, users may view, hear, and read material.
•Qualities that foster creativity. Users may view, edit, and produce media with the use of programmes like iMovie, Photos, and GarageBand.
•Attributes of productivity. People can work with graphics tools using programmes like Pages, Numbers, and Keynote.
•Communication capabilities. Applications like Mail, Messages, and FaceTime are examples of text, visual, and audio communication channels that users can use.
•Organising principles. Utilising programmes like Notes, Reminders, Calendar, Voice Memos, and Contacts, they assist users in finding notes and other content.
•iCloud. Different devices can be used by users to access and share their materials.
•Features for accessibility. Users with impairments can benefit from a number of helpful technologies, including Text to Speech, VoiceOver, and the Accessibility Keyboard.
•Compatible characteristics. From a Windows PC to a Mac, users can move files and other data that are Windows-based. Additionally, they can run Windows or Microsoft Office on a Mac.
Each programme is pre-installed on macOS and functions natively with it. As a result of the apps' special Mac OS X optimisation, the resource allocation is quite effective.
Other new additions to the OS include Live Text, which enables users to copy text that appears in photographs, and focus modes, which let users customise what notifications they receive and when. Universal control, which enables users to use a single keyboard, mouse, or trackpad between Mac and iPad devices, is one of the additional features. The additional security feature known as Recording Indicator allows users to identify which applications have access to the microphone on their Mac.
Security Protections
Defence in depth is a strategy used by macOS, which employs a number of distinct layers of hardware- and software-based security measures. This guarantees that the security of the system as a whole is not jeopardised by a breakdown in one layer.
Secure Enclave
The Secure Enclave is a security chip integrated into Apple silicon-powered devices that is in charge of creating and storing encryption keys for data at rest as well as data from Face ID and Touch ID. It has a unique boot ROM that is separate.
The Secure Enclave can be thought of as the security hub of your device because it is isolated from the rest of the system, includes an AES encryption engine, and a way for safely storing your encryption keys. Even if the main CPU is compromised, it should still be safe.
Touch Id
You can use biometrics to securely unlock your devices with Apple's Touch ID function.
Your biometric information is solely kept in the Secure Enclave and never leaves your device.
Direct Access Memory Protections
Each component on Apple silicon that needs direct memory access is separated. For instance, a Thunderbolt port is unable to access kernel-related memory.
It is written on the basis of research and user experience.
