Homebrew EOL Intel CPU support

September 10, 2026

At WWDC25 on June 9 2025, Apple announced that macOS 27 would no longer support Intel CPUs.

In August 2025, Homebrew announced under Future macOS Support that by the end of summer 2026, Intel CPU Macs would no longer receive binary “bottles” and would be deprioritized to Tier 3 in general. Homebrew Tier 3 status implications includes:

• Homebrew may work, but with a poor and unstable experience
• Migration to a Tier 1 or 2 configuration or to a non-Homebrew tool is strongly recommended

Homebrew is not distributing binary “bottles” for Intel CPU Mac hardware. This means that commands “brew upgrade” or “brew install” may take a long time (hours) as packages are compiled from source - or may even fail.

To temporarily keep an Intel CPU Mac functional with Homebrew, one can try to use older versions of Homebrew formulae that still support Intel CPUs, or compile packages from source manually. For example, GCC 15 can be used to maintain compatibility with Intel CPU Macs.
