• It's amazing to see screenshots of OSX when it launched and think 1. It looks the same as today just a slightly older GUI, but also 2. It's so completely different and has so many more features and how did they nail the framework of the GUI 20 year ago that works today.
• Mac OS was developed to run the Apple Macintosh computer system. Apple computers were introduced in 1984, and Mac OS was the first commercially successful computer to use a GUI and was likely what prompted Microsoft to develop Windows. Early versions of this operating system were known simply as ‘System’ and ‘Finder’.

Amazon EC2 Mac instances enable customers to run on-demand macOS workloads in the cloud for the first time, extending the flexibility, scalability, and cost benefits of AWS to all Apple developers. With EC2 Mac instances, developers creating apps for iPhone, iPad, Mac, Apple Watch, Apple TV, and Safari can provision and access macOS environments within minutes, dynamically scale capacity as needed, and benefit from AWS’s pay-as-you-go pricing.

Powered by AWS Nitro System, EC2 Mac instances are built on Apple Mac mini computers featuring Intel Core i7 processors, and offer customers a choice of macOS Mojave (10.14), macOS Catalina (10.15), and macOS Big Sur (11.2.1). Access the Amazon EC2 Mac User Guide here.

Benefits

Quickly provision macOS environments

Time and resources previously spent building and maintaining on-premises macOS environments can now be refocused on building creative and useful apps. Development teams can now seamlessly provision and access macOS compute environments to enjoy convenient, distributed testing and fast app builds, bringing additional choice to developers so they can use Mac as their trusted platform, on-premises or in the cloud. EC2 Mac instances offload the heavy lifting that comes with managing infrastructure to AWS, which means Apple developers can focus entirely on building great apps.

Reduce costs

EC2 Mac instances allow developers to launch macOS environments within minutes, adjust provisioned capacity as needed, and only pay for actual usage with AWS’s pay-as-you-go pricing. Developers save money since they only need to pay for the systems that are in use. For example, more capacity can be used when building an app, and less capacity when testing.

Extend your toolkits

EC2 Mac instances provide developers with seamless access to dozens of AWS services so they can more easily and efficiently collaborate with team members, and develop, build, test, analyze, and improve their apps. Similar to other EC2 instances, customers can easily use EC2 Mac instances together with AWS services and features like Amazon Virtual Private Cloud (VPC) for network security, Amazon Elastic Block Storage (EBS) for expandable storage, Amazon Elastic Load Balancer (ELB) for distributing build queues, Amazon FSx for scalable file storage, and AWS Systems Manager (SSM) for configuring, managing, and patching macOS environments.

Features

Built on Apple Mac hardware

Amazon EC2 Mac instances are built on Apple Mac mini computers, featuring 8th Generation 3.2GHz (4.6GHz turbo) Intel Core i7 processors with 6 physical/12 logical cores, and 32GiB of Memory.

Enabled by the AWS Nitro System

The AWS Nitro System is a rich collection of building blocks that offloads many of the traditional software-defined functions to dedicated hardware and software to deliver high performance, high availability, and high security. Amazon EC2 Mac instances are uniquely enabled by the AWS Nitro System, which makes it possible to offer Mac mini computers as fully integrated and managed EC2 instances to provide 10 Gbps of VPC network bandwidth and 8 Gbps of EBS storage bandwidth.

Scaled on highly reliable infrastructure

EC2 Mac instances are designed so that customers can build critical applications with confidence. AWS has the most secure, extensive, and reliable global infrastructure for running workloads that require high availability, and is recognized as an industry leader for uptime standards. EC2 Mac instances enable your macOS workloads to benefit from the scale, elasticity, reliability, and experience that AWS’s secure, on-demand infrastructure has offered to millions of customers for more than a decade.

Mac OS – Complete History of Mac OS

On January 24, 1984, Apple Computer Inc.’s chairman Steve Jobs took to the stage of the Apple’s annual shareholders meeting in Cupertino, to show off the very first Macintosh personal computer in a live demonstration. Macintosh 128 came bundled with what was later called the Mac OS, but then known simply as the System Software (or System).

The original System Software was partially based on the Lisa OS, previously released by Apple for the Lisa computer in 1983, and both OS were directly inspired by Xerox Alto. It is known, that Steve Jobs and a number of Apple engineers visited Xerox PARC (in exchange for Apple stock options) in December 1979, to see Alto’s WYSIWYG concept and the mouse-driven graphical user interface, three months after the Lisa and Macintosh projects had begun. The final Lisa and Macintosh operating systems upgraded the concepts of Xerox Alto with menubars, pop-up menus and drag and drop action.

The primary software architect of the Mac OS was Andy Hertzfeld (see the lower photo, he is standing in the middle). He coded much of the original Mac ROM, the kernel, the Macintosh Toolbox and some of the desktop accessories. The icons of the operating system were designed by Susan Kare (the only woman in the lower photo). Macintosh system utilities and Macintosh Finder were coded by Bruce Horn and Steve Capps. Bill Atkinson (the man with the moustache in the lower photo) was creator of the ground-breaking MacPaint application, as well as QuickDraw, the fundamental toolbox that the Mac used for graphics. Atkinson also designed and implemented HyperCard, the first popular hypermedia system.

Just like his direct rival, the IBM PC, Mac used a system ROM for the key OS code. However, IBM PC used only 8 kB of ROM for its power-on self-test (POST) and basic input/output system (BIOS), while the Mac ROM was significantly larger (64 kB), because it contained both low-level and high-level code. The low-level code was for hardware initialization, diagnostics, drivers, etc. The higher-level Toolbox was a collection of software routines meant for use by applications, quite like a shared library. Toolbox functionality included the following: management of dialog boxes; fonts, icons, pull-down menus, scroll bars, and windows; event handling; text entry and editing; arithmetic and logical operations.

The first version of the Mac OS (the System Software, which resided on a single 400KB floppy disk) was easily distinguished between other operating systems then because it does not use a command line interface—it was one of the first operating systems to use an entirely graphical user interface or GUI. Additional to the ROM and system kernel is the Finder, an application used for file management, which also displays the Desktop. The two files were contained in a folder labeled System Folder, which contained other resource files, like a printer driver, needed to interact with the System Software.

The first releases were single-user, single-tasking (only run one application at a time), though special application shells such could work around this to some extent. They used a flat file system called Macintosh File System (MFS), all files were stored in a single directory. The Finder provided virtual folders that could be used to organize files in a hierarchical view with nested folders, but these were not visible from any other application and did not actually exist in the file system.
