iMac 27 inch Tech Notes


Choose Processor

The processor orchestrates all the tasks performed by the hardware and software that make up your iMac. So the more powerful your processor, the faster your iMac will get things done. Both the Intel Core i5 and i7 processors can easily run professional applications like Final Cut Pro and Adobe Photoshop, and handle larger-than-normal files like RAW photos and high-resolution video. They feature a dynamic performance technology called Turbo Boost that automatically boosts power when you need it, based on your workload.

The Intel Core i7 processor takes advantage of Hyper-Threading, a technology that kicks in when the processor is handling several big jobs at the same time. It lets each of the processor’s cores run two threads simultaneously, which means it can do two things at once. So it’s as if your iMac has eight cores at its disposal instead of four, allowing it to multitask more efficiently.

Choose Memory

The more memory you choose, the more apps you can run simultaneously with a higher rate of performance. More memory (RAM) increases performance and enables your iMac to perform better and at a higher speed.

The standard memory configuration is perfect for day-to-day tasks such as email, word processing, and web surfing, as well as complex tasks such as photo editing, creating illustrations, or building presentations.

If you’re working on large projects in professional applications like Logic Pro X or Final Cut Pro X, upgrading your memory will help them run at peak performance.

Choose Storage

Configure your iMac with a large Serial ATA hard drive, choose ultrafast PCIe-based flash storage for incredible performance, or get the best combination of speed and capacity by selecting Fusion Drive.

Flash Storage

Flash storage delivers significantly improved performance compared to a traditional hard drive — speed you’ll notice when you start up your iMac, launch an app, or browse your photo library. Flash storage also uses no moving parts, so it operates silently. For maximum performance, you can configure up to 512GB of flash storage on the 21.5-inch iMac or up to 1TB on the 27-inch iMac.

Fusion Drive

Fusion Drive combines speedy flash storage with a high-capacity hard drive. OS X intelligently manages what goes where, using the flash storage for files you access frequently and keeping the rest of your digital life on the roomier hard drive. Over time, the system learns how you work, so it tailors management of Fusion Drive to work best for you. You can choose a Fusion Drive of up to 2TB on the 21.5-inch iMac and up to 3TB on the 27-inch iMac.

The 1TB Fusion Drive pairs a 1TB hard drive with 24GB of fast flash — enough to store important OS X files and applications to ensure fast startup, near instant wake from sleep and quick application launching, with room left over for your most frequently used files and apps. The 2TB and 3TB Fusion Drives pair a larger hard drive with 128GB of fast flash storage, providing even more space for your most frequently used files. For the best performance, iMac systems with 32GB of memory should be configured with a 2TB or larger Fusion Drive or all flash storage.

Note: 1GB = 1 billion bytes; 1TB = 1 trillion bytes. Actual formatted capacity less.

Choose Graphics

The more advanced your graphics processor, the smoother, crisper, and more detailed your animations, movies, and games will look onscreen. Your iMac with Retina 5K display comes standard with the AMD Radeon R9 M380, M390, or M395 graphics processor with 2GB of dedicated GDDR5 video memory for outstanding graphics performance. For even better graphics performance and additional video memory for more demanding tasks, configure your iMac with the AMD Radeon R9 M395X with 4GB of dedicated GDDR5 video memory.

These graphics processors use AMD’s advanced architecture to deliver more frames per second, smoother animations, and better responsiveness when you’re using graphics-intensive apps like 3D games, high-resolution photo and video editors, and more.

Choose Mouse or Trackpad

Both Magic Mouse 2 and Magic Trackpad 2 are wireless and rechargeable — so you won’t have to replace any batteries — and come paired with your iMac. Magic Mouse 2 comes standard with your iMac, or you can choose Magic Trackpad 2.

Magic Mouse 2

The new design of Magic Mouse 2 lets it glide more smoothly across your desk. And since it supports Multi-Touch, you can use simple gestures on its surface to do things such as swipe between web pages and scroll through documents. So if you prefer using a wireless mouse but want some of the benefits of Multi-Touch, Magic Mouse 2 is a great choice.

Magic Trackpad 2

If you prefer using a trackpad, Magic Trackpad 2 gives you the full range of Multi-Touch gestures and introduces Force Touch technology to the desktop. Sensors underneath the trackpad surface detect subtle differences in the amount of pressure you apply, bringing more functionality to your fingertips and enabling a deeper connection to your content. The new design also features a lower profile, making it even more comfortable to use.

Choose Keyboard and Documentation

Magic Keyboard

The redesigned Magic Keyboard comes standard with your iMac. It’s wireless and rechargeable (so you won’t be replacing batteries), and its ultracompact, edge-to-edge design wastes no surface space. Magic Keyboard has full-size function keys and a lower profile that increases control and comfort. And it pairs automatically with your iMac right out of the box.

Wired Apple Keyboard with Numeric Keypad

The wired Apple Keyboard offers an extended layout that includes document and desktop navigation controls as well as a numeric keypad — an added benefit for gamers and number crunchers alike. It has two USB 2 ports that let you connect a wired mouse as well as a high-speed peripheral such as a digital camera or printer.

Language options

The language option you choose will affect the keyboard layout and documentation that comes with your iMac. OS X is a multilingual operating system. During the setup process, you can choose one of the many languages it supports for application menus and dialogs and for reading and writing text. OS X also allows you to select your preferred language at any time using System Preferences.

Note: Your computer comes equipped with cables appropriate for the country in which you purchased it.
