Homebrew 7.0.0 adds concurrent installs, sandboxing, vulnerability checks; drops macOS 10.15, moves Intel Macs to Tier 3
↗
Homebrew 7.0.0 introduces concurrent package operations, stronger sandboxing, built-in vulnerability checks, and a native macOS app while dropping macOS 10.15 support and moving Intel Macs to Tier 3.
Engineers on Intel Macs face a deprecation timeline ending September 2027, after which Homebrew may stop running entirely, and those on macOS Sonoma 14 or earlier lose prebuilt bottles. The security fixes address high-severity vulnerabilities where unsigned metadata could execute sudo commands and malicious casks could escape the macOS install sandbox. The concurrency improvements meaningfully reduce wait times for Brewfile-driven installations and CI workflows.

Intel Macs are now Tier 3 with no new bottles, and Homebrew recommends migrating to MacPorts before September 2027 when support may end entirely.
Package installation, upgrade, and fetch operations now run concurrently, reducing wait times especially for Brewfile batches and CI pipelines.
Security fixes close a high-severity vulnerability where unsigned cask-removal metadata could execute sudo commands and a moderate-severity sandbox escape via LaunchServices.
