From chromium.gpu:
  Mac Retina Debug (AMD)
  Mac Debug (Intel)
  GPU Mac Builder (dbg)
  Mac Retina Release (AMD)
  Mac Release (Intel)
  GPU Mac Builder

From chromium.mac:
  Mac Builder
  Mac10.10 Tests
  Mac10.11 Tests
  Mac10.12 Tests
  Mac10.13 Tests
 and two more builders I migrated long time ago:
  Mac Builder (dbg)
