A porn blocker you can't uninstall, even though it's your Mac
Last updated November 2, 2026
Any porn blocker can be uninstalled by whoever is an administrator on the computer, and on your own Mac that's you. The only way to get a blocker you truly can't remove is to stop being the administrator. Fullstop does that: it makes your account a standard user and only reveals the admin password 3 days after you ask for it.
Why blockers get uninstalled
You install a blocker when you're thinking clearly. You remove it at 1 a.m. when you're not. Almost every blocker leaves that door open, because removing software is exactly what an admin account is for.
Some blockers add "uninstall protection": they hide the uninstaller, block System Settings, or relaunch themselves when closed. That makes removal annoying, but you're still an admin. An admin can delete files from Terminal, stop background services, or change system settings directly. Annoying doesn't hold up when the urge is strong.
Three ways to make a blocker admin-proof
To make a blocker you can't remove, someone or something other than you has to hold the admin password. There are three ways to do that:
| Who holds the admin password | How it works | The catch |
|---|---|---|
| A friend or partner | They set the admin password and keep it. | You have to tell someone, and ask them every time you need admin. |
| An organization (MDM) | A school, employer or parental-control service manages the Mac remotely. | Someone else controls your computer, and sees what's on it. |
| Time (Fullstop) | The password is held on your Mac and revealed 3 days after you ask. | You wait 3 days for any change. That wait is the point. |
How Fullstop holds the password
- Setup creates a hidden admin account with a random password nobody sees, not even you.
- Your account becomes a standard user. You keep your login password, files and apps. You just can't make system changes.
- Your FileVault recovery key is replaced with one only Fullstop knows, so Recovery Mode isn't a back door.
- You can ask for the code anytime. It arrives 3 days later and works for 24 hours, then the password changes and the Mac locks again.
The clock runs on your Mac, and standard users can't change the date or time. Nothing is sent to a server, so nobody can hand you the code early, including the people who make Fullstop.
What you can't do while it's locked
- Uninstall Fullstop, or stop its background services
- Make yourself an admin again
- Edit the blocklist, or remove its Chrome settings
- Install other browsers or VPNs. They're closed within 2 seconds and deleted.
- Run a virtual machine (a second computer inside your Mac)
You can still use your Mac normally, install macOS updates, install apps from approved companies, and add more blocks instantly.
What it can't stop
To be clear about the limits: Fullstop can't stop someone from erasing or formatting the entire device, which removes Fullstop along with everything else on the disk, or from using a different device. It blocks whole sites and apps, so it doesn't filter posts inside sites that stay open, like YouTube.
Frequently asked
Can I uninstall a porn blocker if I'm the admin?
Yes. On a Mac, an admin can remove any blocker, even one with uninstall protection. That's why Fullstop removes your admin access instead of trying to hide from it.
Is there a porn blocker that can't be bypassed?
On a single Mac, a blocker holds up when you aren't the admin and the usual workarounds are blocked: VPNs, other browsers, incognito, extensions and virtual machines. Fullstop does all of that, and its only exit is a 3-day wait.
Time is what cures an urge. The trouble is, in the moment, none of us has the patience to wait one out. So Fullstop makes the wait for you: every way off takes 3 days, and nobody waits 3 days to goon. No accountability partner, no reports, no account, no card. Mac, Apple silicon.
