What's the best way to block Twitch on Mac for free?

Download the free Focuh app, add twitch.tv and the Twitch app to your blocklist, and start a focus session. Focuh blocks at the macOS system level, so Twitch is unavailable in Chrome, Safari, Arc, Firefox, and the desktop app at the same time. It's completely free with no paid tier, and a browser extension alone can't match it because it only covers one browser.

Can I block Twitch on Mac with a Chrome extension?

You can block Twitch in Chrome with an extension, but only in Chrome. The moment you open Safari, Arc, or the Twitch desktop app, the block does nothing. That's the core weakness of any browser extension on a Mac — it can't see outside its own browser. For Twitch specifically, which has a native app and is easy to open in a second browser, a system-level blocker is far more reliable.

Does blocking twitch.tv also block the Twitch desktop app?

Only if your blocker works at the operating-system level. A website blocker that matches the twitch.tv domain stops the browser version but has no power over the native Twitch app, which connects directly. Focuh blocks both — add twitch.tv to block the site across all browsers, and add the Twitch application to block the desktop app, all within one focus session on macOS.

How do I block Twitch in Safari and Arc, not just Chrome?

Use a system-level blocker rather than a browser extension. Focuh uses macOS Accessibility APIs to block twitch.tv across every browser on the machine at once — Safari, Arc, Chrome, Firefox, Brave, and the rest — during a focus session. You don't install a separate extension per browser; one focus session covers them all, plus the Twitch desktop app, with a single blocklist entry.

Will blocking Twitch slow down my Mac?

No. Focuh checks the active browser tab and the app coming to the foreground through the macOS Accessibility API, which is lightweight, event-driven work — not constant scanning or a background crawler. There's no kernel extension. The overhead is negligible next to the apps you actually run, like your browser, editor, or the games you're trying to stay away from.

Is Focuh free, and does it work on Windows?

Focuh is completely free on macOS — no premium tier, no trial clock, no feature gating. App and website blocking, a focus timer, and task management are all included. It does not support Windows, though; Focuh is macOS-only. If you need to block Twitch on Windows, a cross-platform tool like Cold Turkey or Freedom would be the route instead.

How long should I block Twitch for?

Match it to the work, not the clock. A focus session of 45 to 90 minutes works for a single deep-work block, after which you take a real break. If Twitch is a daily time sink rather than an occasional lapse, longer or recurring sessions tied to your work hours help more. The goal is to make Twitch unavailable during the windows when you most need to concentrate, so the reflex to open it has nothing to land on.

How to Block Twitch on Mac (Free) — 2026

Q: Can I unblock Twitch on Mac if I need it?

Yes. Focuh blocks Twitch only while a focus session is active, so when the session ends, Twitch is available again. If you need it mid-session, you can revoke Accessibility permission in System Settings to stop blocking — deliberate friction rather than a hard lock. Most people find that having to dig through settings is enough to ride out the urge and keep the session going.

You sit down to work, open one stream "just for background," and ninety minutes later you've watched three speedruns and learned nothing about your actual task. Twitch is built to hold attention, which makes it a problem precisely when you can't afford to lose any. This guide shows you how to block Twitch on Mac for free — across every browser and the desktop app — and why the Chrome-extension approach falls apart almost immediately.

The fast answer

To block Twitch on Mac, download the free Focuh app, add twitch.tv and the Twitch desktop app to your blocklist, and start a focus session. Focuh blocks at the macOS system level, so Twitch is gone in Chrome, Safari, Arc, Firefox, and the native app at the same time. It's completely free, with no paid tier and no trial clock. A browser extension can't do this because it only ever controls one browser.

Why a Chrome extension can't block Twitch on Mac

A browser extension blocks the browser it's installed in. That's the whole limit. Block twitch.tv with a Chrome extension and you've blocked it in Chrome — and nowhere else. Twitch makes that gap especially easy to fall through:

It opens fine in Safari or Arc with one keystroke.
It has a native desktop app an extension can't see.
You can disable the extension in two clicks when the urge hits.

So the Chrome-only block works right up until the first time you want Twitch badly enough to open a second browser — which, with Twitch, tends to be the same afternoon. If your distraction lived entirely in Chrome, an extension would be fine; for a multi-browser, has-an-app site like Twitch, it isn't. The system-level vs browser blocking guide lays out exactly where each approach wins.

How to block Twitch on Mac with Focuh

Download the free Focuh app and open it.
Grant Accessibility permission when prompted — System Settings → Privacy & Security → Accessibility. This is what lets Focuh block across the whole system.
Add twitch.tv to your blocked sites, and add the Twitch application to your blocked apps.
Start a focus session and choose its length.

During the session, twitch.tv won't load in any browser and the Twitch app won't come to the foreground. When the session ends, both are available again. The setup takes about three minutes once, and after that it's one click to start a block.

What system-level blocking covers that an extension doesn't

Where Twitch hides	Chrome extension	Focuh (system-level)
Twitch in Chrome	Blocked	Blocked
Twitch in Safari / Arc / Firefox	Open	Blocked
Twitch desktop app	Open	Blocked
Switching browsers to bypass	Easy	Doesn't help
Disabling mid-session	Two clicks	Requires System Settings

The pattern is clear: an extension plugs one hole and leaves the rest open, while OS-level blocking closes them together. That's the difference between a block you'll bypass by lunchtime and one that actually holds.

How does Focuh's blocking work?

Focuh uses macOS Accessibility APIs. With that permission granted once, it can see which browser tab is active and which application is coming to the foreground, and it acts on your blocklist during a focus session. Because it operates above any single browser, one blocklist entry for twitch.tv covers every browser at once — you don't install and configure a separate extension in Chrome, Safari, and Arc.

There's no kernel extension and no background disk scanning, so it won't slow your Mac down. The Accessibility approach is lightweight and event-driven; the only real cost is granting that one permission at setup, which is the price of blocking that works system-wide instead of inside a single app.

Can you still bypass it?

Yes, and that's intentional. Focuh blocks Twitch only while a session is running, and you can revoke Accessibility permission in System Settings to stop blocking entirely. It's friction, not a vault. For most people, having to open System Settings and dig for the toggle is enough to let the urge pass and keep working. If you want blocking strong enough to resist even uninstalling, that's Cold Turkey's territory — see Focuh vs Cold Turkey for where each one fits.

Block Twitch alongside your other time sinks

Twitch rarely travels alone. If you block it during work, you'll usually want to block whatever you'd switch to next — YouTube, Reddit, a game in your dock. Focuh blocks websites and apps in the same session, so you can add youtube.com, reddit.com, and the Discord or Steam apps to the same blocklist and shut the whole set of escape hatches at once.

That's the advantage of an app blocker over a pure website blocker: the next distraction after Twitch is often a native app, and a website blocker can't touch it. The best free app blocker for Mac guide goes deeper on blocking applications specifically, and the best website blockers for Mac roundup covers the field.

Why blocking beats willpower

Twitch is engineered by people whose full-time job is keeping you watching — autoplay, raids, the next clip queued before the current one ends. Willpower has to win that fight every single time you glance at the dock. A block only has to win once: it removes the option, so the reflex to open Twitch has nothing to land on. You're not out-disciplining the platform; you're taking the option off the table during the hours you can't spare it.

Tie each session to a specific task and the block stops being "Twitch is off" and becomes "I'm working on this for the next hour." That framing — work plus removed distraction — is what makes the block stick past the first day.

Which option should you pick?

You're on a Mac and want Twitch gone everywhere — Focuh, free, blocks site and app across all browsers in one session.
You only ever use Twitch in Chrome — a Chrome extension will cover that single browser.
You want unbreakable blocking and don't mind paying — Cold Turkey, after weighing Focuh vs Cold Turkey.
You need Windows support — a cross-platform tool; Focuh is macOS-only.

Twitch is too easy to reopen in another browser for a Chrome-only block to hold. If you want it actually gone while you work, block it at the system level. Download Focuh free and shut Twitch in every browser and the app at once.
