Apple MacBook longevity depends on software support and hardware

The longevity of a new MacBook is determined by both software support and hardware capabilities. A primary factor is macOS compatibility; Apple typically supports the current version of macOS and the two previous iterations with security patches, offering approximately eight years of official support.

Notably, the upcoming macOS 27 Golden Gate, expected in late 2026, is anticipated to mark the end of support for Intel-based machines, shifting exclusivity toward the Apple Silicon architecture introduced in 2020. After official support ends, users may face compatibility issues with third-party applications.

Hardware limitations also play a significant role. Since modern MacBooks do not allow for hardware upgrades after purchase, initial configurations of RAM and processor are critical for long-term performance. Additionally, the battery is designed to maintain optimal capacity up to 1,000 cycles, after which battery life may decrease significantly.
