- Split View supports up to four pages, and agent control is off by default.
Field notes
Migration runs on the Mac: the page says OpenArch reads Arc’s spaces, tabs, logins, extensions, and settings without uploading data or changing Arc. It also describes separate profiles for spaces, split views of up to four pages, and optional browser control through Chrome DevTools MCP; agent access is off by default. The page limits current builds to Apple silicon on macOS 15 or later and says early builds are not notarized.
