StarBlocker for macOS

StarBlocker for Mac

On a Mac, StarBlocker is the whole product: a background agent captures the screen every ten seconds, reads it locally, and judges it against your rules. There is no quit button and no list to keep up to date.

What Mac can and cannot do

On Mac, StarBlocker does the whole product: every app and every browser is judged.

Requirements

macOS 13 Ventura or later
Apple Silicon (M1 or newer)
Screen Recording permission, granted once at setup

Setting up

Download the .dmg and run StarBlocker.pkg; it asks for your administrator password because it installs a service that starts at login.
Grant Screen Recording when macOS asks. Without it StarBlocker sees nothing and blocks nothing.
Log in from the menu bar icon and write your first rule on the dashboard.

Download StarBlocker after signing up; the download page always has the current build.

What people block on Mac

Every device, one account

* On iPhone, StarBlocker judges everything you do in Safari. It cannot see inside other apps: those can be blocked or time-limited, but not judged.

Questions

Can I quit it from the menu bar or Activity Monitor?

No. It runs as a LaunchAgent and relaunches if closed. Removing it takes fifteen minutes, and your accountability partner is emailed.

Does it block Safari, Chrome, Firefox and Arc?

All of them, and every other app, because it judges the display rather than hooking a browser.

Does it slow the Mac down?

Most scans stop before they cost anything: an unchanged screen is skipped, and text is read locally. Only a frame that needs a judgment is sent, downscaled.

Does it work with a Windows PC and an iPhone too?

Yes. One account, the same rules, limits and missions on every device, and a break earned on one applies to all.

One account covers every device you own. Sign up, write a rule, install.
