Apple iMac 24" (2024) Apple M4 (8-core CPU) / 24GB RAM / 1TB SSD

Manufacturer: Apple

The Apple iMac 24″ (2024) with the M4 8-core CPU is a compact all-in-one computer that brings together Apple's silicon architecture and a large integrated display in a single unified chassis. Built around a 3-nanometer chip with 28 billion transistors, it delivers a unified computing experience where the processor, memory, and storage are tightly integrated rather than treated as separate components.

The display measures 24 inches with a resolution of 4480×2520 pixels at 218 pixels per inch and a typical brightness of 500 nits, refreshing at 60Hz. On the connectivity side, the machine includes two Thunderbolt ports, USB Type-C, Bluetooth 5.3, and Wi-Fi 6E support. The M4 chip supports up to 120 GB/s of memory bandwidth, and the 24GB of LPDDR5 RAM runs at up to 6400 MHz. Additional features include a 12MP front-facing camera with 3D facial recognition, a fingerprint scanner, Dolby Atmos audio through stereo speakers, and 1TB of flash storage — all within a chassis weighing approximately 4420 grams.

Pros
  • The 4480 x 2520 resolution across a 24-inch panel results in a pixel density of 218 ppi, producing a sharp and detailed image for everyday use
  • Dual Thunderbolt ports combined with USB Type-C and Wi-Fi 6E support provide a range of wired and wireless connection options
  • Biometric authentication is covered on two fronts, with both a fingerprint scanner and 3D facial recognition available for secure login
  • The 12MP front camera makes the system well-suited for video calls and conferencing without requiring an external peripheral
  • A top energy efficiency rating indicates the unit is designed to minimize power consumption during operation
  • The internal power supply keeps the external footprint clean, with no separate power brick required on the desk
Cons
  • The display is capped at a 60Hz refresh rate, which may not suit users who require smoother motion for fast-paced content
  • There is no Ethernet port, meaning wired network connectivity is not available without an additional adapter
  • The display does not support HDR10, HDR10+, or Dolby Vision, limiting high dynamic range content rendering
  • No anti-reflection coating is present on the screen, which may affect visibility in brightly lit environments
  • The system supports only one external display, restricting multi-monitor setups
  • There is no external memory card slot, so expanding or transferring storage requires a separate adapter
Who is this for?

This all-in-one is a strong fit for users who spend their days in productivity-focused workflows such as document editing, communication, and creative tasks that don't demand extreme GPU loads. The 4480 x 2520 display at 218 ppi makes it particularly well-suited to anyone who values sharp text rendering and detailed image work, including graphic designers and photo editors working in standard dynamic range. The inclusion of a 12MP front camera with 3D facial recognition, Dolby Atmos audio, and a fingerprint scanner also makes it a comfortable choice for professionals who rely heavily on video conferencing and secure, fast authentication throughout the workday.

Who is this NOT for?

Users who require a multi-monitor setup will find this machine limiting, as it supports only one external display. The 60Hz refresh rate and absence of HDR support make it a poor match for anyone involved in motion-intensive gaming or HDR video production, where higher refresh rates and wide dynamic range rendering are essential. Additionally, the lack of an Ethernet port and external memory card slot means that users who depend on stable wired networking or frequent high-speed media transfers — such as videographers offloading footage from camera cards — will face friction without additional adapters.
