About This App

Launch Services is a developer and power-user tool for macOS that provides a graphical browser to the system's Launch Services database. It allows inspection of bundle IDs, file type associations, and the UTI (Uniform Type Identifier) hierarchy — functionality normally accessible only via command-line tools like lsregister. The app is useful for debugging app registration issues, understanding file-type routing, and examining how macOS maps file extensions to handler applications.

The vendor explicitly states that Launch Services is Intel-only with no native Apple Silicon build planned. The app continues to run under Rosetta 2 today, but Apple is removing Rosetta in macOS 28 (September 2028), at which point this tool will stop working entirely. You have roughly two years to plan your migration. For most macOS development work, the command-line lsregister tool (found at /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/) and system logging via `log stream` provide equivalent information without a GUI. If you rely heavily on the graphical interface for debugging, consider filing a feature request with Thomas Tempelmann asking for native Apple Silicon support, or investigating whether Swift-based alternatives like examining LaunchServices programmatically via the native Swift APIs would meet your needs.
