The app includes the resources needed to launch the installer interface and to create external install media from Terminal.

Safety overview

Status: Safe

This is a legitimate Apple installer used to install or reinstall macOS Tahoe. It does not function like a typical daily-use app, but it can make major system changes because its purpose is to install an operating system. That level of access is normal for an installer from Apple. Keep it only if you plan to install, upgrade, reinstall, or create bootable installation media, and make sure you have a current backup before starting an OS installation.

Recommendation: Keep Install macOS Tahoe if you still need it for an upgrade, reinstall, or bootable installer. If macOS Tahoe is already installed and you do not expect to use the installer again, you can remove the app to free storage space.
