The 6 core eighth- or ninth-generation Intel Core i5 processor and Radeon Pro 570X, 575X or 580X graphics processor ensure powerful performance, while macOS Mojave allows you to use your iMac like a pro. It includes two USB-C ports, the Magic Mouse 2 and Magic Keyboard, as well as 802.11ac Wi-Fi. These features ensure this iMac gives you a seamless user experience—all on a 5mm thin screen.
