BlockBlock Helper
BlockBlock Helper is a macOS background component for Objective-See's BlockBlock that helps monitor persistence changes and alert you to new startup items.
What is BlockBlock Helper?
BlockBlock Helper is part of BlockBlock, a macOS security utility from Objective-See that watches common persistence locations for newly installed startup components. It is used by people who want extra visibility into login items, launch agents, launch daemons, and other mechanisms software can use to run automatically. In normal use, the helper works in the background so BlockBlock can provide alerts when something adds persistent execution on the Mac. BlockBlock also lets users create allow or block rules for these events and keeps logs of alert responses. This is a security and privacy tool for Mac users who want to audit what is trying to establish persistence on their system.
Key features
- Monitor common macOS persistence locations for new startup items
- Alert you when software tries to install persistent execution
- Let you allow or block detected persistence events
- Create rules for future persistence decisions
- Review and manage saved rules from the app
- Log alert responses for later review

Safety overview
Status: Mostly safe
This helper is associated with BlockBlock's normal security function and background monitoring. BlockBlock uses elevated system access and Full Disk Access for its persistence-monitoring role, and some protections can also require Accessibility permission; those requests are consistent with what the app does. Keep it only if you intentionally use BlockBlock, and make sure it was installed as part of BlockBlock from Objective-See.
Recommendation: Keep BlockBlock Helper if you use BlockBlock for startup-item and persistence monitoring on your Mac. If you no longer use BlockBlock, remove it through BlockBlock's own uninstaller or app removal workflow so its background components and permissions are cleaned up together.
