In-Depth Overview
What is Arc?
Arc is a free Chromium-based browser from The Browser Company that rethought browser chrome around focus and organisation. Its signature is a sidebar with vertical tabs, Spaces that act like themed desktops for work, personal and projects, Split View for side-by-side browsing, Peek for hover previews, Easels and Boosts for lightweight page customisation, and a command-palette experience inspired by productivity launchers. Between 2022 and 2024 Arc was the design reference that every new browser was measured against, and it popularised the spatial metaphor now copied by Zen Browser, Vivaldi and others. As of May 2025 the company placed Arc in maintenance mode to build Dia. Official messaging as of August 2026 is unambiguous: arc.net recommends Dia for users who want active feature development and positions Arc as receiving Chromium updates only. Arc still downloads for macOS and Windows, still supports Chrome extensions, and still feels polished, but it no longer represents The Browser Company's future. On Apple Silicon Macs with macOS Tahoe 26 it runs fine, but features such as Boosts, Easels and Arc Max AI experiments are effectively frozen. The practical consequence is that new users should treat Arc as legacy software — beloved, usable, but not a forward-looking default — and existing users should export bookmarks, note their Spaces structure and plan a move to Dia, Zen Browser, Vivaldi or Safari rather than doubling down on Arc.
What is Microsoft Edge?
Microsoft Edge is Microsoft's free, Chromium-based browser for macOS, Windows, Linux, iOS and Android, and the default browser on Windows. On Mac it is a fully native Apple Silicon and Intel app, notarised and supported on macOS Tahoe 26 with automatic updates. Beyond the Chromium baseline, Edge adds Microsoft-specific value: Copilot AI chat in the sidebar powered by OpenAI models including GPT-5.6 family capabilities surfaced through Microsoft Copilot, Workspaces for shared tab groups, Collections for research, vertical tabs, split screen, Immersive Reader, sleeping tabs and efficiency mode for battery life, strong extension compatibility via the Chrome Web Store and Edge Add-ons, and enterprise integration with Microsoft 365, Entra ID, Intune and Defender SmartScreen. Pricing is straightforward: Edge is free for personal and commercial use with no paid tier for the browser itself; optional costs sit in Microsoft 365 or Copilot for Microsoft 365 subscriptions if you want the full enterprise AI suite. As of August 2026 Edge is on a rapid stable channel with security fixes backported quickly, a clear advantage over a maintenance-mode product. For Mac users who live in Microsoft 365, need managed profiles, or want a Chromium browser that is actively hardened and audited for enterprise use, Edge is a pragmatic, well-supported choice. For privacy purists it is less aggressive than Brave by default, but tracking prevention presets and InPrivate browsing provide a reasonable baseline.
Detailed Feature Comparison
Development status & security cadence
CriticalMaintenance mode since May 2025. The Browser Company confirms Arc receives Chromium security updates only while all new feature and security-narrative investment is in Dia. Usable today on Tahoe 26, but not a forward-looking default for new installs.
Full active development on a four-week stable cadence, with out-of-band security patches, SmartScreen, and enterprise update controls via Intune. Native Apple Silicon and Intel builds notarised for Tahoe 26.
Verdict: Edge wins decisively on being alive as a product with predictable patching. Arc's Chromium-only maintenance cannot match a living browser roadmap.
Tab & workspace organisation
HighSpaces with profiles, pinned tabs, vertical sidebar, Split View and Peek remain the most opinionated and polished spatial model. Even frozen, it feels calmer than conventional browser windows for heavy tab users.
Workspaces for shared tab groups, Collections, vertical tabs, split screen and tab groups via Chromium. Functional and collaborative, but less spatial and aesthetic than Arc's sidebar-first design.
Verdict: Arc still wins pure workspace UX for users who loved its metaphor. Edge is pragmatic and collaborative, but not as beloved for personal organisation.
AI & productivity assistance
HighArc Max experiments are effectively frozen. The Browser Company's AI browser story has moved to Dia, which offers integrated AI assistance. Arc itself has no evolving AI assistant in 2026.
Copilot sidebar with grounding on open tabs, page summarisation, Compose, and Microsoft 365 Copilot integration where licensed. Powered by current frontier models including GPT-5.6 family capabilities surfaced through Microsoft. Constantly iterated.
Verdict: Edge's Copilot is the living, maintained AI assistant. Arc's AI is legacy.
Privacy & tracking protection
HighRespectable Chromium baseline privacy historically with tracker blocking options, but without Brave-level fingerprinting defences or ongoing privacy feature work.
Tracking prevention with Basic/Balanced/Strict presets, SmartScreen, and InPrivate browsing. Enterprise-friendly, but not as aggressive as Brave or Firefox by default. Defender integration helps enterprise deployments.
Verdict: Both are mainstream Chromium on privacy. Brave or Orion beat both if privacy is the top criterion; between these two the difference is policy presets rather than philosophy.
Performance & battery on Mac
MediumChromium performance with efficiency dependent on Spaces discipline. Running many Spaces and Boosts can increase memory. Apple Silicon runs well but optimisation focus is now Dia.
Chromium with sleeping tabs, efficiency mode, and startup boost optimised for battery on MacBooks. Frequently cited for lower background power use than Chrome in Microsoft's benchmarks.
Verdict: Edge edges ahead on measured battery and sleep optimisations for MacBook users.
Extensions & compatibility
HighChrome Web Store compatible via Chromium, though sidebar constraints occasionally affect extension UI. Dia compatibility is separate and not equivalent.
Full Chrome Web Store support plus Edge Add-ons store, with enterprise extension management via Intune. Best long-term extension ecosystem assurance among the two.
Verdict: Edge is safer for long-term Chrome extension compatibility and managed deployment.
Platform parity & pricing
MediumFree Mac and Windows clients; iOS companion was never as strong as desktop. Dia is Apple Silicon macOS 14+ only, which narrows the Browser Company future for Intel users.
Free on macOS, Windows, Linux, iOS and Android with sync, profiles and enterprise roaming. No paid browser tier. Microsoft 365 features are subscription-based but browsing itself is free forever.
Verdict: Edge wins on free multi-platform parity today. Arc's successor Dia is platform-restricted; Arc itself is free but frozen.
Enterprise & manageability
MediumNo enterprise story. No MDM controls, no conditional access, no fleet hardening. Never designed for managed Mac fleets.
Intune, Entra ID, conditional access, IE mode successor controls, Defender SmartScreen, and policy catalog for managed Macs. The only credible enterprise browser in this pair.
Verdict: Edge is the enterprise browser. Arc has no enterprise proposition.
Who Should Choose Which?
1Microsoft 365 power user on Mac
Workspaces, Collections, Copilot grounding on open tabs, and Entra ID sync make Edge the coherent choice when your work lives in Microsoft 365 and you need Tahoe 26 support with enterprise controls.
2Designer who loved Arc Spaces
If the spatial sidebar metaphor is non-negotiable, try Dia if you have Apple Silicon and macOS 14+, otherwise Zen Browser for an open-source Arc-like. Edge will feel utilitarian in comparison even though it is the safer long-term default.
3IT admin managing a Mac fleet
Intune policies, conditional access and SmartScreen are prerequisites for a managed fleet. A maintenance-mode browser without MDM controls cannot be approved.
4Student on a MacBook Air concerned about battery
Sleeping tabs and efficiency mode measurably reduce background power use. Arc's charm does not offset battery cost when many Spaces stay alive.
5Existing Arc user with 200 tabs
Export bookmarks, screenshot Spaces, trial Edge Workspaces and Dia if eligible, and set a two-week migration window. Staying on a frozen product beyond a bridge period grows security debt.
Migration Guide
Arc → Microsoft Edge
In Arc, export bookmarks and passwords, note Spaces structure and Boosts. Install Edge via Homebrew (brew install --cask microsoft-edge) or Microsoft's installer, sign in for sync, enable vertical tabs and Workspaces to recreate Spaces, enable tracking prevention to Balanced or Strict, install essential Chrome Web Store extensions, and pin Collections for research. Keep Arc read-only for a week to catch stragglers.
Microsoft Edge → Arc
Not recommended for new users in 2026. If you must test Arc nostalgia, install knowing updates are Chromium-only and trial Dia instead for long-term Browser Company continuity. Recreate Workspaces manually as Spaces.
Final Verdict

Runner-up
Scores are Bundl.run editorial ratings out of 10 across 8 criteria (the feature comparison above), last reviewed August 2026.
Microsoft Edge is the rational default for most Mac users choosing between these two Chromium browsers in August 2026. Its active four-week releases, enterprise hardening, Copilot AI, Workspaces and proven Tahoe 26 support make it a living product you can standardise on. Arc remains a design classic whose spatial UX still delights, but its maintenance-mode status means it cannot be recommended as a new default.
Bottom Line: Install Microsoft Edge for a supported, AI-capable Chromium browser on macOS Tahoe 26. Keep Arc only as a bridge while you migrate to Dia if you have Apple Silicon and macOS 14+, or to Zen Browser, Vivaldi or Brave if you want an Arc-inspired future that is actively maintained.
