Blockerflow for Mac 1.0.1

Important

macOS may say "Blockerflow is damaged and can't be opened"

The app is not damaged. Blockerflow for Mac is distributed without an Apple Developer licence, so it is not signed or notarized by Apple, and macOS blocks apps it cannot verify.

After you drag Blockerflow into Applications, open Terminal and run this one command:

xattr -cr /Applications/Blockerflow.app

Then open Blockerflow again. You only need to do this once per install. You can also try right click, then Open, then Open again.

Support: help me get an Apple Developer ID (€99 a year) to sign Blockerflow for macOS and iOS, so it opens without warnings. Donate via PayPal

What is new in 1.0.1

• The status card now tells the truth. In 1.0.0 it said "Protection active" even when the filter was not running. It now checks every few seconds and shows "Protection is off" with a Turn on button when nothing is being filtered.
• Turn on starts the filter and keeps it starting with the app. In 1.0.0 a copy with auto start off could never filter, and nothing in the app could fix that.
• A cancelled administrator prompt for the hosts file no longer stops the filter from starting, and the prompt no longer appears when there is nothing to change.
• Uninstall Protection now locks every file in the app, not just the folder.

If you installed 1.0.0, turn off Uninstall Protection in Settings first, then drag the new app over the old one.

What is in it

• System wide filtering through a local proxy, with the same shared blocklists as Android.
• Blocks adult content, piracy sites, Instagram and Facebook Reels, YouTube Shorts and Snapchat Spotlight, and closes blocked apps.
• Accountability partners: Myself, Time Delay, Friend and AI Coach.
• Focus Mode, a blocklist and whitelist of your own, and Uninstall Protection.
• Google sign in to sync your settings with the Android app.
• Tested with Safari, Chrome, Firefox, Opera, Vivaldi, DuckDuckGo, Brave, Microsoft Edge, Orion and Yandex.

About the "Source code" files below

Ignore Source code (zip) and Source code (tar.gz). GitHub adds them to every release automatically, and they contain the code of the blockerflow.net website, not the Blockerflow Mac app. The only file you need is Blockerflow-mac-1.0.1.dmg.

If you need the source code of the Blockerflow Mac app, you can request it at hello@khaleel.eu.
