Apple's M4 all-in-one features four Thunderbolt 4 ports (two on the base 8-core-GPU model), all USB-C and mounted on the rear for a clean desk setup. Every one of them carries DisplayPort output, enabling up to two external 6K displays alongside the built-in 24-inch 4.5K Retina screen. Gigabit Ethernet is uniquely integrated into the magnetic power adapter rather than the computer itself. A 3.5mm headphone jack on the left side of the chassis supports high-impedance headphones.

Notes & Compatibility
This record documents the four-port iMac (Mac16,3). Every USB-C port on the back carries DisplayPort video, and Apple supports up to two external 6K displays at 60Hz or one 8K display at 60Hz. There is no HDMI and no USB-A, so older accessories need a USB-C adapter or hub. Gigabit Ethernet is not on the iMac itself: it lives on the external 143W power adapter, so the network cable runs to the power brick, not the screen. The two-port iMac has no Ethernet on its adapter and needs a USB-C Ethernet adapter instead. The 3.5mm headphone jack on the left side supports high-impedance headphones and headsets with an inline mic. Built-in 24-inch 4.5K Retina display, Wi-Fi 6E and Bluetooth 5.3.
