Complete Mac protection

More protection than Screen Time, built for the Mac. A kid can’t turn it off.

Screen Time is free, built in, and a good first step, especially on a phone. On a Mac it’s easy to bypass and limited to time controls. Kidfence is a complete protection layer built for macOS: app and game blocking by code signature, network filtering, locked DNS and SafeSearch, browser lockdown, and screen-time that freezes, all enforced from a system service that a kid can’t simply switch off.

The one a kid can’t turn off

On a Mac, Screen Time can often be worked around: creating or switching to another user account, signing out of the Apple ID, or changing the system clock, and some of these have published write-ups. Kidfence is designed so those don’t work. Enforcement runs from a system service that stays in effect across a new account, a sign-out, a clock change, and a reboot, and removing it needs the parent admin password the child doesn’t have.

Protection that goes further than Screen Time

Screen Time does time limits and basic web restrictions. Kidfence layers in the protections a determined kid on a Mac actually tests.

Apps & games, blocked for real

Roblox, Minecraft, Steam, Discord, or any app, blocked by code signature, so renaming the app to Homework.app doesn’t bypass it. Endpoint Security blocks at launch.

The whole web, filtered without a VPN

Adult sites, social, and time-sinks blocked at the network layer via SNI, with category and per-domain rules that go well beyond Screen Time’s web limits. No tunnel, HTTPS stays intact.

AI catches new sites Screen Time can’t

Kids hunt for fresh game, proxy, and unblock sites every week. Screen Time has no notion of categories for an unknown site. Kidfence uses AI to categorize unfamiliar sites on the fly, beyond a curated list of roughly 500,000 known ones, and blocks games, adult, and proxy sites so a brand-new URL isn’t an automatic loophole.

Locked DNS & SafeSearch

Family-safe DNS and SafeSearch on Google, Bing, and YouTube are pinned on at the network layer. They can’t be toggled off in the browser, and manual DNS edits are reverted automatically.

Browser lockdown

Kids download Firefox, Brave, or Arc to dodge filters. Kidfence blocks every browser except Safari and Chrome by signature, and disables incognito and private browsing, so there’s no filter-free way around it.

Closes the search-results loophole

Screen Time’s “Allowed Websites Only” is painful in practice: one page pulls in dozens of other domains you’d have to approve one by one, and it doesn’t pin SafeSearch on. A plain Google search for “js games” then surfaces playable games right in the results. Kidfence enforces SafeSearch, blocks game domains, and locks the browser down, so that gap is closed.

Closes the Gmail Chat loophole

Kids use school Gmail to chat all day. Kidfence’s browser extension hides the Chat, Spaces, and Meet panels while email keeps working, something Screen Time can’t do.

Instant “what’s he on?” with AI advice

Ask any time and get the live list of every tab open right now, with how long they’ve lingered on each. The AI reads it back in plain English, flags a quick break that’s become an hour on a game site, and suggests what to do, instead of leaving you to dig through Settings panes and charts.

Screen Time first. Kidfence when it isn’t holding.

If Screen Time is doing the job for your family, keep using it, it’s free and well made. Kidfence is for the Mac where it isn’t holding up: a kid who’s found the workarounds, a laptop that’s really a homework machine, and a parent who wants protection that goes past time limits.

Common questions

How does a kid get around Screen Time on a Mac?

The usual ones we hear are: creating or switching to another user account, signing out of the Apple ID, changing the system date and time, and deleting and re-downloading an app. Some of these have published write-ups. Kidfence is designed so those don’t work: enforcement is system-wide and survives account changes, sign-out, clock changes, and reboots.

What about Apple’s “Allowed Websites Only” setting?

It works in theory but rarely in practice. Modern pages pull resources from dozens of other domains, so an allow-list means approving site after site just to make ordinary pages load, and it doesn’t pin SafeSearch on. With a search engine reachable, a query like “js games” returns playable games right in the results. Kidfence takes the opposite approach: filter everything by default at the network layer, enforce SafeSearch, block game domains, and lock the browser down, so there’s no allow-list to maintain and the search loophole is closed.

Is Kidfence worth paying for when Screen Time is free?

Only if free isn’t holding. If your kid hasn’t found the workarounds and a passcode is enough, Screen Time is great. Kidfence is worth it when the Mac is a real distraction battleground and you want enforcement a kid can’t shrug off, plus app blocking, web filtering, browser lockdown, and plain-English control that Screen Time doesn’t offer.

Does Kidfence replace Screen Time?

You can run both. Many families keep Screen Time for its built-in basics and add Kidfence for stronger app blocking, web filtering, and a bedtime that freezes apps. They don’t conflict.

What about their phone?

The phone is the one place the platform owners do this well: a managed child account with Family Sharing or Family Link is genuinely hard to disable. The Mac is the gap, and that’s what Kidfence focuses on, doing the Mac properly rather than every device half-well.
