What is the best browser for Mac?

The best browser for Mac depends on what you value: Safari is deeply integrated with macOS, Chrome has the biggest extension ecosystem, and Sigma combines top benchmark speed, the lowest RAM use, and built-in AI, all for free.

What is the fastest browser for Mac?

In our Speedometer 3.0 tests on a MacBook Pro M4, Sigma was the fastest browser for Mac: 1.30x faster than Safari and 1.13x faster than Chrome.

What is the best browser for Mac other than Safari?

If you want to move beyond Safari, Sigma offers Chromium compatibility with lower RAM use than Chrome or Brave, plus a built-in AI agent and local AI that no other Mac browser includes.

What is the most secure browser for Mac?

Look for open-source code, tracking protection, and minimal data collection. Sigma ships all three, plus a built-in ad blocker, phishing protection, and on-device AI processing.

How do I change my default browser on a Mac?

Open System Settings → Desktop & Dock, scroll to 'Default web browser,' and pick your browser from the list. In Sigma you can also set it right in the browser's settings under Default browser.

How do I open private browsing on a Mac?

Every browser has its own way. In Sigma, just flip the Private Mode toggle on the start page. Private tabs use DuckDuckGo search and keep sessions fully separated from your main profile.

Is Sigma Browser free on Mac?

Yes. Sigma is completely free for macOS, including the AI agent, AI chat, deep research, and local AI.

Does Sigma run on Apple Silicon Macs?

Yes. Sigma runs on Apple Silicon (M-series) Macs, and our benchmarks are measured on a MacBook Pro M4.
