AdGuard for Safari

Ad blocking extensions for Safari are having hard time since Apple started to force everyone to use the new SDK. AdGuard extension is supposed to bring back the high quality ad blocking back to Safari.

Unlike other major ad blockers, AdGuard provides some extra features you are used to have with the traditional (now deprecated) extensions:

Managing protection from Safari
Choose among popular filter subscription
Custom filters
Creating your own filtering rules
Manual blocking tool
Allowlisting websites

AdGuard for Safari is based on the Safari native content blocking API, which makes it lightning fast, but somewhat limited in capabilities. For instance, Safari limits the number of rules a content blocker can have.

Better yet, there is a full-fledged AdGuard for Mac

With all above said, there is a solution that is even more effective than AG Safari extension. I mean, of course, AdGuard for Mac. It can:

filter your traffic in all browsers and apps on your Mac
have an unlimited number of filter rules
provide a better filtering quality (due to the lack of browser API restrictions)

You can try it out for free.

Preparing and building Adguard.

Environment requirements

MacOS 10.14.4+
Xcode 10.2+
Dev account on developer.apple.com and Adguard Software Limited membership, enabled App Store Connect
Certificates Developer ID Application: Adguard Software Limited (TC3Q7MAJXF) and Developer ID Installer: Adguard Software Limited (TC3Q7MAJXF) in keychain

Check certificates names in Scripts/ExportOptions.plist

Building

SafariConverterLib dependency

For converting rules to content-blocker format we use an external library as a binary built from https://github.com/AdguardTeam/SafariConverterLib/, that ConverterTool binary should be placed in ./libs/.

You use ./Scripts/download-lib.sh to download the latest release version of that binary from Github.

Preparation - notarization

In case we need to notarize the app, we will need to do it.

"Because App Store Connect now requires two-factor authentication (2FA) on all accounts, you must create an app-specific password for altool, as described in Using app-specific passwords. To avoid including your password as cleartext in a script, you can provide a reference to a keychain item, as shown in the previous example. This assumes the keychain holds a keychain item named altool_access with an account value matching the username [email protected]. Note that altool can’t access your iCloud keychain for security reasons, so the item must be in your login keychain. You can add a new keychain item using the Keychain Access app, or from the command line using the security utility:
security add-generic-password -a "[email protected]" -w <secret_password> -s "altool_access"

Create Scripts/.devconfig.json with created username and keychain item.

Common issues

https://developer.apple.com/documentation/security/notarizing_your_app_before_distribution/resolving_common_notarization_issues

Use fixed electron-osx-sign

npm install -g electron-userland/electron-osx-sign#timestamp-server
