On July 3, 2001, Apple suspended production of the Power Mac G4 Cube, marking one of the company’s most memorable product failures and the first major setback following Steve Jobs’ celebrated return in 1997.
Although Apple suggested that the striking transparent computer could return in the future, the G4 Cube was never revived. It was eventually overtaken by newer Mac systems powered by G5 processors and, later, Intel Core chips.
A New Direction for Apple Design
The Power Mac G4 Cube marked an important shift in Apple’s design strategy. When Steve Jobs returned to the company, products such as the original iMac and iBook attracted attention with their bright colors and playful appearance. These computers helped Apple stand apart from the plain beige desktops that dominated the personal computer market at the time.
As Apple’s design team continued to evolve, Jony Ive and his colleagues began moving toward a cleaner and more restrained visual style. The G4 Cube reflected this new direction with its compact shape, transparent outer shell and minimalist industrial appearance. That design approach later became a major part of Apple’s identity, influencing products that emphasized simple lines, premium materials and uncluttered layouts.
Apple did eventually bring color back to some of its products, including the M1 iMac introduced in 2021. However, the company’s broader design language remained closely tied to the sleek and understated look that began emerging around the time of the G4 Cube.
The cube-shaped computer also appeared to reflect Steve Jobs’ long-standing interest in unusual geometric designs. Years earlier, while leading NeXT, Jobs introduced the NeXTcube, another computer built around a cube-like form. Although the NeXTcube earned attention for its design and technical ideas, it achieved only limited commercial success.
The Power Mac G4 Cube followed a similar pattern. It became admired for its appearance and engineering, but its distinctive shape did not translate into strong sales. Even so, the product remains an important example of Apple’s willingness to experiment with form, materials and desktop computer design.
The Power Mac G4 Cube: Striking Looks, Surprising Openness
Few people ever argued that the Power Mac G4 Cube wasn’t a beautiful piece of hardware. Instead of the boxy tower shape Mac users were used to, it took the form of a compact seven-inch cube made of clear acrylic, appearing almost suspended in midair thanks to its transparent base. There was no fan inside — the whole thing cooled itself passively through convection, which meant it ran in near-total silence. It also introduced a touch-sensitive power button, a small design detail that hinted at technology Apple would later refine for the iPhone.
One thing I always appreciated about the Cube is that it carried forward something Apple had championed back in the mid-1990s: easy expandability. Popping open the bottom panel — helped along by a built-in pop-up handle — gave owners straightforward access to the internal components. That’s a sharp contrast to the Macs that came after it, which became notoriously difficult to open, let alone upgrade.
The Cube also held its own on specs and pricing for the era. The entry-level configuration started at $1,799, offering a 450-MHz G4 processor, 64MB of RAM, and a 20GB hard drive. For those wanting more power, Apple sold a beefed-up model exclusively through its online store for $2,299, with a faster chip and additional memory and storage. Keep in mind, though — like most desktop Macs at the time, the display was sold separately.
