Captured material
This discussion records users encountering unsupported-macOS warnings on Monterey. It illustrates that a package manager may still execute on an OS outside its supported testing matrix; successful local use does not imply supported bottle availability or maintainer support. Treat individual experiences as reports, with the archived support-tier policy providing the project-level requirements.
Decision-relevant context
Source locator: Discussion #5603, opened September 14, 2024; accepted answer and February 2025 exchange.
Jmuccigr reported an unsupported warning on September 14, 2024, with Homebrew 4.3.21 on macOS 12.4 arm64. Bo98's accepted answer that day said CI covered three macOS versions and Monterey capacity had moved to macOS 15 the previous day. The expectation that 12.7.6 would be Monterey's final update is a participant forecast, not an Apple guarantee.
On February 22, 2025, filpedroso asked for clearer, less harsh warnings. p-linnane cited hardware cost, volunteer effort, and fewer duplicate issues, while distinguishing brew execution from bottle coverage. filpedroso's February 23 reply accepted the explanation. This outcome concerns that exchange, not universal agreement.
Other users discuss patching macOS or switching systems. Their successes and failures are reports, not supported migration procedures.
Applicability and limits
Only the facts used by this repository are captured in this original-word account. This is not a full transcript or current-version implementation guarantee.
Project interpretation
This evidence motivates a legacy platform scope without promising that a particular unsupported install fails immediately. The opening report is arm64; it illustrates an OS-window policy, not an Intel-specific defect.
Omissions and evidence gaps
The page reports 8 comments and 52 replies, with some previous replies collapsed. This capture covers the relevant visible exchange; it cannot establish complete discussion chronology or endorse third-party patchers.
Preservation
This UTF-8 Markdown record is readable without a browser, script, account, or network. Preserve it with the repository and SHA256SUMS; retain superseded records when replacing a source version. Original URLs identify provenance, not a runtime dependency.
Review: 2026-09-26 UTC. Original source re-read against the cited local sections; added locators, conditions, and explicit gaps. No runtime validation is inferred. This account expands the earlier summary without replacing its historical date.
