Chromium-legacy is the up-to-date browser¹ for legacy Mac OS X / OS X / macOS series no longer officially supported:

• Mac OS X 10.7 / Lion
• OS X 10.8 / Mountain Lion
• OS X 10.9 / Mavericks
• OS X 10.10 / Yosemite
• OS X 10.11 / El Capitan
• macOS 10.12 / Sierra
• macOS 10.13 / High Sierra
• macOS 10.14 / Mojave

NB: Not for officially supported macOS (10.15+).

Equivalent to the same version of the original Chromium except for limitations by old OSes (see limitations).
Some features (i.e. DRM) need an extra setup to use.

Tested with the latest build of Mac OS X 10.7 or later:

• 10.7.5 (11G63)
• 10.8.5 (12F2560)
• 10.9.5 (13F1911)
• 10.10.5 (14F2511)
• 10.11.6 (15G22010)
• 10.12.6 (16G2136)
• 10.13.6 (17G14042)
• 10.14.6 (18G9323)

For getting/updating the latest builds, the following options are available:

• manually from the Releases page
• an updater
  • a lightweight updater to simply check and download updates
• a downloader by @Wowfunhappy
  • an automatic updater with several workarounds/addons
  • NB: some Chromium's native features (e.g. sync) may be disabled by this downloader, and may need modifications to use those

Canary builds are automatically built and uploaded several times a week.
And note, uploaded without any tests, thus there is no guarantee for launching or proper operation.
It's recommended to find and use a stable build for daily use. (The same is true for the original Chrome Canary/Chromium)

See Releases for recent builds.

Stable builds are based on Chrome's stable channel branch and passed a few basic tests (launching, HTML5/JS tests, media playing) on 10.7 - 10.14.

See releases/tag/stable for the current stable channel release.

• UI
  • unified window title & tab bar
    • not available on 10.7/10.8/10.9, replaced by classical title bar instead (thanks to @Wowfunhappy)
  • menus/sheets
    • have no shadow, indistinguishable from the background
  • scrollbars
    • won't disappear despite the "Show scrollbars when scrolling" option being enabled when GPU compositing is disabled
• GPU assists
  • on 10.7, due to the old OpenGL version, disabled entirely by embedded policy
  • on 10.8/10.9, GPU compositing is disabled by the hardcoded --disable-gpu-compositing option due to rendering glitches.
• DRM (Widevine)
  • usable with limited resolution/compatibility
  • need to setup to use
• U2F/WebAuthn/FIDO2
  • on 10.7, you need patched IOHIDFamily.kext to use USB keys
