How do I block Roblox on my Mac?

Roblox is harder to block than a normal website because most people play through the Roblox Mac app, not the browser. Blocking roblox.com in a browser does nothing to the desktop app. For a full block you need a system-level tool that can block native apps — Focuh blocks both the Roblox app and the roblox.com website during a focus session, and Cold Turkey can too. The hosts file and SelfControl block the website but may not stop the app launching.

Can I block the Roblox app on Mac, not just the website?

Yes, but only with a tool that works at the system level. Browser extensions and basic blockers only touch roblox.com in the browser and leave the Roblox Mac app fully playable. Focuh blocks the Roblox app directly using macOS Accessibility APIs, so the app won't open for the length of a focus session. Cold Turkey can also block apps. If the player only ever uses Roblox in a browser tab, a simpler website block is enough — but most don't.

How do I block Roblox on Mac for free?

A few free options exist with trade-offs. The hosts file blocks roblox.com across every browser and disrupts the app's connection, but needs Terminal. SelfControl blocks the website and can't be turned off until its timer ends. Focuh is free and blocks both the roblox.com website and the native Roblox app at the system level, tied to a focus timer. For the most thorough free result, pick a tool that handles the native app, not just the website.

How do I block Roblox on a Mac for my child?

Use macOS Screen Time with a parent passcode. Under Content & Privacy Restrictions you can block roblox.com as a website and restrict apps, and the child can't lift it without your code. Screen Time's website limits work best in Safari, so on a family Mac it helps to set Safari as the main browser. For a stricter setup, pair Screen Time with a system-level blocker so other browsers and the Roblox app are both covered.

Will blocking roblox.com stop the Roblox Mac app too?

No. The Roblox Mac app launches games directly without opening a browser, so blocking the website leaves the app fully working. This is the single most common mistake — people block roblox.com, feel done, then watch the app open straight from the dock. To stop Roblox completely you have to block the app itself, which only system-level tools like Focuh or Cold Turkey can do. The website block is one of two doors, not both.

How do I block Roblox during homework or study hours only?

A timer or schedule beats an all-day ban, which tends to turn Roblox into forbidden fruit. Focuh blocks Roblox only while a focus session runs — start the timer, the app and website are blocked, and they unblock when it ends — which fits a homework block well. Cold Turkey supports fixed recurring schedules if you'd rather block, say, 4pm to 6pm on weekdays. Tying the block to study time makes it part of a routine instead of a punishment.

Does blocking Roblox in Safari also block it in Chrome?

Only if you block at the system level. Screen Time's website limits mainly affect Safari and leave Chrome, Firefox, and Edge untouched, so a determined player just opens another browser. The hosts file, SelfControl, and Focuh all block roblox.com across every browser at once because they work below the browser layer. A single-browser extension blocks Roblox in that one browser only, which is why browser-only blocks tend to fail on a shared Mac.

What's the most reliable way to block Roblox on a Mac?

Block it at every layer: the website across all browsers, the native Roblox app, and — for a child — behind a parent passcode. A browser extension covers only the first browser. On a Mac, Focuh blocks both the roblox.com website across every browser and the Roblox app at the system level in one move, which closes the two doors a website-only block leaves open. Add Screen Time on top if you need a child not to be able to lift it.

How to Block Roblox on Mac (2026)

June 15, 20269 min readFocuh

Roblox is built to be hard to leave — endless games, friends already in a session, and a launcher that drops you straight back in. If it's eating homework time or pulling a kid away from the table, blocking it on the Mac is reasonable. This guide covers how to block Roblox on a Mac honestly: the website part is easy, but the Roblox app is where most blocks quietly fail.

The fast answer

To block Roblox on a Mac properly, you need a tool that blocks the native Roblox app, not just the website — because the app launches games without ever opening a browser. The free Focuh Mac app blocks both roblox.com across every browser and the Roblox app itself during a focus session, using macOS Accessibility APIs. Start a timer, Roblox is unreachable until it ends, and it comes back on its own for a break.

Why Roblox is harder to block than a normal website

Most blocking guides assume the distraction is a website. Roblox breaks that assumption. There's a web version at roblox.com, but the vast majority of players use the native Roblox Mac app, which launches games directly and has nothing to do with your browser.

That means blocking roblox.com in a browser does nothing to the app sitting in the dock. You'll feel like you've blocked Roblox, then watch it open straight from the launcher a minute later. To actually block Roblox you have to account for both the website and the native app — and only system-level tools can reach the app. The same gap shows up with the Roblox block on Chrome, which covers the browser side but can't touch the Mac app.

How to block the Roblox app on Mac with Focuh

Download the Focuh Mac app and install it.
In Settings, add roblox.com to your blocked sites.
Add the Roblox app to your blocked apps list.
Grant Accessibility permission when prompted — a one-time setup.
Start a focus session. Both the Roblox website and the native app are blocked until the timer ends.

Because the block is tied to a timer, Roblox comes back the moment the session finishes. That suits a homework block well: gone while the work happens, back for a break. The same app-blocking approach works for any native game or program — the full pattern is in how to block apps on Mac.

Ways to block Roblox on Mac, compared

Method	Free?	Blocks web	Blocks Roblox app	All browsers	Timer-based
Focuh	Yes	Yes	Yes	Yes	Yes
Screen Time	Yes	Safari only	Partial	No	Schedule
Hosts file	Yes	Yes	Partial	Yes	No
SelfControl	Yes	Yes	No	Yes	Timer
Cold Turkey	Paid	Yes	Yes	Yes	Schedule

The split is clear: the methods that fully block the native Roblox app are the ones that work at the system level. Browser-bound and Safari-only methods leave the app as an open backdoor. For more on which Mac blockers handle native apps well, see the best free app blocker for Mac roundup.

The free methods, briefly

Hosts file. Open Terminal, run sudo nano /etc/hosts, and point roblox.com at 127.0.0.1. This blocks the Roblox website in every browser and disrupts the app's connection, though the app may still launch and show its menus. It's free, has no scheduling, and stays on until you manually undo it — fine for an adult, fiddly for a family setup.

SelfControl. This free, open-source app blocks a domain list until a timer expires and can't be lifted early, even by rebooting. It blocks roblox.com across browsers, but it blocks websites only — the native Roblox app isn't on its radar — so pair it with quitting the app. Good for an older student who wants a self-imposed block they can't cheat.

Screen Time. Built into macOS and free. Under Content & Privacy Restrictions you can block roblox.com and restrict apps behind a parent passcode, which makes it the right starting point for a child. The catch is that its website limits lean on Safari, so on a family Mac it helps to make Safari the default and add a system-level blocker for other browsers.

How do I block Roblox for a child on a Mac?

If this is about a kid, lead with Screen Time because a child can't lift it without your passcode. Open System Settings, go to Screen Time, turn on Content & Privacy Restrictions, and add roblox.com under web content limits. Under app restrictions, limit or block the Roblox app as well.

The weak spot is browsers. Screen Time's web limits mostly catch Safari, so a child who knows their way around can open Chrome or Firefox and reach Roblox again. To close that, set Safari as the family browser and add a system-level blocker on top so every browser and the app are covered. If free parental tools keep getting bypassed, Cold Turkey offers harder locking, and Focuh blocks the app plus the website across browsers during sessions.

Blocking Roblox during study time, not all day

A blanket all-day ban often backfires — it turns Roblox into the thing they sneak rather than something with a time and place. Tying the block to specific stretches tends to stick better, for kids and adults alike.

A timer-based block fits a homework routine: start a focus session, Roblox is gone for its length, and it lifts automatically at the end. That's the Focuh model, and it reads as part of the routine rather than a punishment. A scheduled block suits fixed hours — Cold Turkey can block Roblox every weekday from 4pm to 6pm — at the cost of flexibility on a day that runs differently. If your evenings are unpredictable, a timer you start on demand beats a calendar rule you'll end up overriding.

Which method should you use?

You want Roblox blocked for yourself, app included — the free Focuh Mac app blocks the app and the website across browsers during sessions.
You're blocking it for a younger child — Screen Time behind a parent passcode, plus a system-level blocker for other browsers.
You want a block you can't lift early — SelfControl's irreversible timer, paired with quitting the Roblox app.
You only need the website gone in one browser — a free Chrome extension covers that, with the app and other browsers left open.

A website block is the easy half, and on its own it's the half that fails — the Roblox app opens straight from the dock, and another browser is one click away. Close both doors and the block actually holds. Download Focuh free to block the Roblox app and the website across every browser, or grab the free Chrome extension if all you need is the browser tab.
