What's the best Mac app to block YouTube?

For most people, Focuh is the best fit. It's a free Mac app that blocks youtube.com across every browser during a focus session, pairs the block with a timer and task board, and uses macOS Accessibility APIs that make it hard to bypass. Cold Turkey and SelfControl are also strong for hard blocking. Screen Time can block YouTube but only in Safari. The advantage of a system-level app is that switching to a second browser or the YouTube desktop app doesn't get around the block.

How do I block YouTube on my Mac for free?

Use a free system-level blocker. SelfControl is free, open source, and blocks youtube.com across all browsers for a timer you set. Focuh is free and blocks YouTube at the OS level during a focus session, with a timer and kanban board around it. macOS Screen Time can block youtube.com too, but only in Safari. You don't need to pay to block YouTube on a Mac — free tools cover the blocking, and paid apps mainly add cross-device sync or strict schedules.

Can a Mac app block the YouTube app and Shorts, not just the website?

A system-level Mac app blocks YouTube across every browser, so the website is covered wherever you open it, and a tool like Focuh can also block native desktop apps. Blocking youtube.com stops Shorts on the web too, since Shorts live on the same domain. On a Mac most YouTube use is in a browser, so a system-level website block usually covers Shorts and regular videos in one go. To stop Shorts specifically, see our guide on blocking YouTube Shorts on Mac.

Why is a Mac app better than a Chrome extension for blocking YouTube?

A Chrome extension only blocks tabs in Chrome, so opening Safari, using the YouTube desktop app, or disabling the extension all get around it. A Mac app blocks YouTube across every browser at once and is harder to switch off mid-session. If you only ever watch YouTube in Chrome, an extension is enough. But if you tend to switch browsers when blocked, a system-level app removes that escape route — which is usually why the block actually holds.

How hard are these YouTube blockers to bypass?

It varies. A browser extension is easiest to disable — a few clicks. Screen Time can be lifted with the passcode. SelfControl is hard to stop once its timer starts, even after a restart. Focuh blocks via Accessibility APIs and is built to be hard to disable mid-session. No blocker on your own machine is truly unbreakable, but the difference between a one-click extension and a system-level app is large, and when you're tempted to 'just watch one video' that friction is the point.

Can I block YouTube on a schedule on my Mac?

Yes. Cold Turkey supports recurring schedules in its paid version, so you can block YouTube every weekday from 9 to 5 automatically. Screen Time has App Limits and Downtime that can restrict youtube.com in Safari on a schedule. Focuh is session-based rather than scheduled — you start a focus session and YouTube is blocked until it ends — which suits people who block in bursts rather than fixed hours. Pick scheduled or session-based depending on how your day runs.

Do free Mac YouTube blockers collect my data?

The good ones don't. SelfControl is open source and runs entirely locally. Focuh stores settings and session data on-device and ships no telemetry. Screen Time is built into macOS and stays on your machine. Always check the privacy policy, but the core free tools for blocking YouTube on a Mac don't require an account or send your browsing anywhere. That's what you want from a tool that sees which sites you're trying to avoid.

What's the best way to block YouTube during work but allow it after?

Session-based blocking handles this cleanly. Instead of an all-day ban, start a focus session during work hours so YouTube is blocked while you're in deep work and freely available afterward. Focuh works this way and adds a timer and task board so you can see the session winding down. If you prefer fixed hours, Cold Turkey's schedules or Screen Time's Downtime can block youtube.com automatically during your workday and lift it in the evening.

Best Mac App to Block YouTube (2026)

June 26, 202610 min readFocuh

Blocking YouTube on a Mac is harder than it sounds, because YouTube follows you everywhere — Chrome, Safari, the desktop app, the autoplay sidebar. The best Mac app for the job blocks youtube.com across every browser during a focus session and is hard enough to switch off that "just one video" doesn't turn into an hour. For most people that's Focuh, and it's free. This guide compares the strongest options for 2026 on cost, how completely they block, and how easy they are to bypass.

A Chrome extension blocks YouTube in Chrome and nowhere else. That's fine if Chrome is the only place you watch. But the moment you open Safari to get around the block — or click the YouTube app in your Dock — an extension is done. A system-level Mac app is what closes those gaps.

What makes a good YouTube blocker on Mac?

Three things separate a blocker that actually keeps you off YouTube from one you uninstall in a week.

It covers every browser. YouTube doesn't live in one browser. If a block only handles Chrome, Safari is one click away and the block is meaningless.

It's session-based or scheduled, not just an honor-system toggle. Tying the block to a focus session or a recurring schedule keeps YouTube gone while you work and available afterward, which is far easier to sustain than a permanent ban.

It's hard to disable mid-session. The whole value is friction in the moment you reach for "one quick video." If turning it off is trivial, it won't survive a slow afternoon.

Best Mac apps to block YouTube, compared

App	Free?	Blocks all browsers	Scheduling	Hard to bypass	Best for
Focuh	Yes	Yes	Session-based	Yes (Accessibility APIs)	Blocking in focus bursts with a timer
Cold Turkey	Free tier; paid Pro	Yes	Yes (paid)	Yes	Recurring weekday schedules
SelfControl	Yes (open source)	Yes	No (manual timer)	Yes (timer can't be stopped)	A free, unbreakable timed block
Screen Time	Built into macOS	Safari only	Yes (Downtime)	Moderate (passcode)	Light blocking if you only use Safari

The column that catches most people out is "blocks all browsers." Screen Time looks like the obvious free choice because it's built in — but it only blocks youtube.com in Safari, so opening Chrome defeats it instantly. For a block that holds, you want coverage across every browser.

What is Focuh?

Focuh is a free Mac app that blocks distracting websites and apps during a focus session. Start a session, add youtube.com, and YouTube is blocked across every browser — and the desktop app — until the timer ends. It uses macOS Accessibility APIs, which is what lets it reach native apps and makes it hard to switch off mid-session.

Around the block, Focuh adds a visual focus timer and a kanban task board, so the work you meant to do stays in front of you instead of the video you just lost access to. There's no account, no telemetry, and no ads; everything stays on your device. Because blocking youtube.com covers Shorts too (they're on the same domain), you don't need a separate Shorts blocker — though our how to block YouTube Shorts on Mac guide covers the edge cases.

When do Cold Turkey, SelfControl, or Screen Time fit better?

Cold Turkey is the pick if you want YouTube blocked on a recurring schedule — every weekday 9 to 5, automatically. Its free tier blocks websites; scheduling and stricter locks are in the paid Pro version. Once a block is locked, it's genuinely hard to undo.

SelfControl is the free, no-frills choice. Open source, it blocks youtube.com across all browsers for a timer you set, and it cannot be stopped once started — not by quitting, restarting, or deleting the app. The trade-off is no scheduling and no structure around the block. For a pure, unbreakable timed block, it's excellent; see our SelfControl alternative comparison for where it falls short.

Screen Time is worth a mention because it's free and built in, but the Safari-only limit is a real problem for YouTube. If Safari is genuinely the only browser you use, Screen Time's Downtime and App Limits can block youtube.com on a schedule without installing anything. For everyone with a second browser, it leaks. Our Screen Time alternative comparison explains why.

Mac app vs Chrome extension for blocking YouTube

If you only ever watch YouTube in Chrome, the Focuh Chrome extension is free and enough. The signal to upgrade to a Mac app is simple: if you've ever opened Safari specifically to watch a video you blocked in Chrome, an extension can't help you. A system-level app blocks every browser at once. See how to block YouTube on Mac for the full walkthrough and system-level vs browser blocking for the reasoning.

Which YouTube blocker should you choose?

"I want free blocking in focus bursts with a timer" — Choose Focuh. Blocks YouTube across every browser and adds structure around the session.

"I want a free, unbreakable timed block" — Choose SelfControl. No scheduling, but the timer can't be stopped.

"I want YouTube blocked on a recurring weekday schedule" — Choose Cold Turkey, paid Pro for schedules.

"I only ever use Safari and want something built in" — Screen Time works, with the Safari-only caveat.

No app will make YouTube stop being interesting. But the right one makes opening it take more effort than the impulse is worth — and on a Mac in 2026, the cleanest free way to block YouTube across every browser is a system-level session blocker.
