Compatibility & release channels.

Minimum: macOS 26
Verified: 23 July 2026

Built for macOS 26 and later

Termy requires macOS 26 or later. Its native SSH, SFTP, terminal, Host X-ray, automation, and Incident Capsule workflows are designed around the current macOS platform.

01. System requirement

macOS 26 or later: required to install and run Termy.
Earlier macOS releases: not supported.

02. Release channels

Stable — Production-ready. Monthly. Commercially supported; security fixes can ship outside the calendar.
Beta — Working preview. As needed. Explicit opt-in; known limitations and regressions are possible.
Labs — Experimental. No promise. No compatibility or support promise; capabilities may change or disappear.

Channels use separate signed update feeds. Change channel in Termy → Settings → About. Stable is the default and the only channel covered by the commercial support promise.

03. Integration maturity

1Password SSH Agent — Stable. Termy reads public identities and delegates signing; private keys are never copied.
Tailscale / MagicDNS inventory — Beta. Local discovery only; Termy stores host metadata, never tailnet credentials or account profiles.
termyctl portable inventory — Beta. Versioned, size-bounded, secret-free JSON; commands and raw output are outside the schema.

04. Release rule

A release is compatible only after the same artifact builds for the macOS 26 deployment target and passes clean-install launch testing on supported macOS releases. Signing, notarization, activation, update, and the core SSH path are separate release gates.
