All-in-One for home and study

The 21.5-inch Retina 4K iMac combines the display, computer and speakers in a single unit. It runs macOS Ventura on an Intel Core i3 3.6 GHz quad-core processor with 8 GB DDR4 RAM and a 1 TB HDD. The design suits home offices, students and general creative work.

Upgrading from older Macs or basic PCs

Replacing a pre-Retina iMac or an entry-level Windows all-in-one brings a much sharper 4K panel and the modern macOS Ventura environment. The jump is worth it when you need accurate colour for photos or a cleaner desk without a separate tower and monitor.

Buyers who want a simple Mac desktop

This model fits users who prefer macOS for web browsing, office apps, light photo editing and media playback. It is not for buyers who want more storage speed than a hard drive provides, builders who need a second card, or anyone requiring user-upgradeable memory.

商品問答

What are the exact dimensions of the 21.5 inch iMac so I can check desk clearance?

The all-in-one measures 17.72 inches high, 20.79 inches wide and 6.89 inches deep.

How is the memory upgraded on this model and what mistake do installers make?

The 8 GB DDR4 SO-DIMM slots are behind a hatch on the rear; the common error is forgetting to press each module firmly until the side clips click.

When will the internal 1 TB hard drive likely need replacement?

A mechanical 1 TB HDD typically shows wear after three to five years of daily use; plan to swap it for an SSD when boot times lengthen.
