BlockBlock Installer
BlockBlock Installer is the macOS installer component for Objective-See's BlockBlock, a security tool that monitors persistence locations for new startup items.
What is BlockBlock Installer?
BlockBlock Installer is the installation component used to set up BlockBlock on macOS. BlockBlock is a security and privacy utility that monitors common persistence locations, such as login items and launch agents, and alerts you when new components try to install themselves so you can allow or block them. People typically use it to watch for potentially unwanted background software, adware, or malware that tries to remain active after restart. The installer helps place the app and its supporting components where BlockBlock can run correctly as a system-level protection tool. This is a native Mac utility from Objective-See, designed for users who want extra visibility into what is trying to make itself persistent on their Mac.

Safety overview
Status: Mostly safe
This installer belongs to a legitimate Mac security tool and its elevated setup behavior is normal for software that monitors persistence and startup mechanisms. During installation or first use, it may request permissions needed for security monitoring. Keep it if you use BlockBlock or want its protection features; removing it can disable BlockBlock's monitoring and alerts.
Recommendation: Keep this item if you use BlockBlock or want ongoing monitoring of startup persistence on your Mac. If you no longer use BlockBlock, remove the app through its normal uninstall method so its helper components are cleaned up together.
