CLUtil12
CLUtil12 is a Brother printer utility for macOS that handles driver communication, printer configuration, and print job management for Brother laser and inkjet printers. Based on the bundle ID prefix, it is a component of Brother's printer driver suite rather than a standalone application. It manages device discovery, network connectivity, and firmware updates for Brother devices on local networks.
AI Recommendation
1 suggestionCLUtil12 is a helper component of Brother's printer driver suite, not a separately updatable application. To ensure native Apple Silicon support, you should update the parent Brother printer driver package — either through Brother's download page (brother.com/support), the Mac App Store if your driver was installed that way, or by reinstalling the full driver suite for your specific printer model. Contact Brother support with your printer model number if you need clarification on which driver package includes CLUtil12. With Apple removing Rosetta 2 in macOS 28 (September 2028), it is important to verify that your current Brother driver has a native Apple Silicon build available, or plan to update when Brother releases one.
