What's the big deal about operating systems in the first place? What do they actually do? An operating system is the level of programming that lets you do things with your computer. The operating system interacts with a computer's hardware on a basic level, transmitting your commands into language the hardware can interpret. The OS acts as a platform for all other applications on your machine. Without it, your computer would just be a paperweight.

Review your Mac's system information. There are several tabs at the top of the 'About This Mac' window that you can use to view different type of information: Overview - View your Mac's operating system, processor, and memory information here. Displays - View information about your Mac's screen and any attached displays.

At its heart, a computer is a number-crunching device. It takes input in the form of zeros and ones -- bits -- and channels them through various circuits and processors. The hardware behaves according to strict rules. We define these rules using things like logic gates, which take input and produce an output in a predictable way. Some simple computers have no need of an operating system because they only perform a specific task. But personal computers need to be more versatile. The operating system allows complex programs to access the capabilities of the hardware to get results. Only the hardware's physical properties and our own imaginations can limit what programs can do.

• MacOS (originally named 'Mac OS X' until 2012 and then 'OS X' until 2016) is the current Mac operating system that officially succeeded the classic Mac OS in 2001. Although the system was originally marketed as simply 'version 10' of Mac OS, it has a history that is largely independent of the classic Mac OS.
• Mac OS This is the operating system that runs on Macintosh computers. It is pronounced, 'mack-oh-es.' The Mac OS has been around since the first Macintosh was introduced in 1984.

You could design an operating system by physically programming it into a computer's circuits. This would require building electrical pathways using millions of logic gates. But such an operating system would be inflexible. That's why operating systems like Mac OS X and Windows are software. Software is more malleable than hardware -- you can make changes through software patches and version updates. To do the same with hardware would mean switching out physical chips and circuit boards.

Operating systems are like the manager for a computer. Choco v1 4 2 – design photo collages. It's the job of the OS to monitor what software needs and what the hardware can provide. As you run applications on your computer, the OS allocates the resources necessary to complete the task. That can include processing power, memory allocation and computer storage access, among other things. Ideally, the OS will make sure that your computer's hardware is never overtaxed.

The OS also allows programs to run on a computer. Without an OS, a programmer would have to design an application to run on the hardware directly. This isn't very efficient. An operating system acts as an application interface to the hardware. The OS does this through an application program interface (API). Program developers build applications for the API. Assuming the programmer has done a good job at building an application without any serious bugs, it should run just fine on the operating system.

One important part of the Mac computer is the firmware. Firmware is a level of programming that exists directly on top of a hardware layer. It's not part of the operating system itself. Mac select screen capture. The Mac firmware is the first stored program that executes when you turn on a Mac computer. Its job is to check the computer's CPU, memory, disk drives and ports for errors. Any video converter mac os x. The PC equivalent to the Mac firmware is called BIOS, which stands for basic input-output systems. A second program called a bootloader loads the Mac OS X, assuming there are no errors reported by the firmware.

Next, we'll take a closer look at what makes the Mac OS X tick.

Mac Os Operating System Info

The System Information app provides detailed specifications and other information about your Mac hardware and software, including your network and external devices. In some versions of OS X, this app is called System Profiler.

Choose Apple menu  > About This Mac. This opens an overview of your Mac, including your Mac model, processor, memory, serial number, and version of macOS. To see the greater detail provided by the System Information app, click the System Report button.

To open System Information directly, press and hold the Option key and choose Apple menu  > System Information. You can also use Spotlight to find System Information, or open it from the Utilities folder of your Applications folder.

System Information opens to a system report for your Mac:

Select items in the sidebar to see information about each item. For example:

• The Hardware section shows your Mac serial number
• The Memory section shows how much RAM is installed in each internal memory slot.
• The Software section shows which startup disk (boot volume) your Mac is using.
• The Network section shows details such as your IP address, the connections allowed by your macOS firewall, the signal strength of nearby Wi-Fi networks, and more.
