Ready-to-use all-in-one desktop

The Apple iMac MRT32LL/A is a 21.5-inch all-in-one computer with a Retina 4K display running at 4096 x 2304 resolution. It is powered by a 3.6 GHz quad-core Intel Core i3 processor and 16 GB of DDR4 memory. The system includes a 256 GB flash drive and AMD Radeon Pro graphics with dedicated GDDR5 video memory.

Suits home and office users needing a compact

This iMac fits buyers who want a complete Silver desktop with integrated FaceTime HD camera, stereo speakers and Gigabit Ethernet in a single unit. It is not for users who require user-upgradable memory beyond the 64 GB maximum, internal optical drive support or discrete graphics configurations not built into this model.

Bundled input devices complete the setup

The included USB keyboard and optical mouse provide immediate wired control without separate purchases. Four USB 3 ports, three Thunderbolt ports and a Mini DisplayPort output expand connectivity for storage, displays and peripherals. An SDXC card slot adds direct media import for photographers and video editors.

商品問答

Does the iMac need an external display, keyboard or mouse to operate?

No — the 21.5-inch Retina 4K display, USB keyboard and optical mouse are all included in the box.

Can I connect my older Thunderbolt 2 hard drive to the three Thunderbolt ports on this iMac?

The ports are Thunderbolt 3 (USB-C); a Thunderbolt 2 device requires a certified Thunderbolt 3-to-2 adapter to work.

How do I verify the Radeon Pro 555 graphics are active after first boot?

Open About This Mac → System Report → Graphics/Displays and confirm the AMD Radeon Pro 555 with 2 GB GDDR5 is listed as the active GPU.
