ENService 1.0
ENService 1.0 is a macOS helper component installed with EndNote to support citation and bibliography workflows in companion apps.
What is ENService 1.0?
ENService 1.0 is a background helper installed as part of EndNote on Mac. It supports EndNote’s reference-management workflow by helping the main app integrate with writing and research tasks such as citing sources and formatting bibliographies in supported document workflows. EndNote is used by students, researchers, faculty, and professional writers to collect references, organize libraries, manage PDFs, and produce citations in required styles. On macOS, users typically encounter helper components like this during installation, troubleshooting, or cleanup rather than as a standalone app they launch directly. If you use EndNote for academic writing or manuscript preparation, this component belongs to that environment and helps the overall product function as intended.
Key features

Safety overview
Status: Mostly safe
This item is part of the EndNote software environment and is generally expected on Macs where EndNote is installed. It may run in the background or be called by other parts of EndNote to support citation-related features. Removing it can stop parts of EndNote or document-integration features from working correctly. If you no longer use EndNote, remove it by uninstalling the full app rather than deleting pieces individually.
Recommendation: Keep ENService 1.0 if you use EndNote or open documents that depend on its citation tools. If EndNote has already been removed and you are cleaning up leftovers, uninstall the remaining EndNote components together so related writing features are removed cleanly.
