Block gambling on Mac
OFFBET blocks gambling across your whole Mac — 390,000+ betting sites and casino apps stopped in every browser and app. It filters locally with a background helper — nothing is ever sent to a remote server — and it's PIN-locked so you can't quietly switch it off. Sign in once and Essential is free forever.
How OFFBET blocks gambling on Mac
System-wide DNS filtering
A privileged OFFBET helper runs a local DNS resolver right on your Mac and drops gambling domains before any page loads — so the block works in every browser and every app, not just one.
PIN-locked anti-tamper
Uninstalling OFFBET is PIN-gated with a cooling-off delay, and a background watchdog re-arms the filter — and if you've paired a Companion, tamper attempts alert them.
Bypass-proof
It closes the escape routes: a built-in firewall blocks VPNs, every browser is steered onto the local filter with Secure DNS (DoH) switched off, and any change to your DNS is set straight back.
