CanoScan LiDE 100
CanoScan LiDE 100 is Canon's official scanning driver and software for the LiDE 100 flatbed scanner, a consumer-grade document and photo scanner discontinued in the early 2010s. The driver provides basic scanning functionality including image acquisition, document feed detection, and integration with the system's TWAIN interface for use in third-party applications like image editors or document managers. The app was originally designed for macOS 10.3 through 10.6 and has not received updates for modern operating systems.
AI Recommendation
1 suggestionCanon stopped supporting the LiDE 100 scanner many years ago — no official macOS drivers exist for modern operating systems, and the app will not launch on recent Intel or Apple Silicon Macs. The Intel version continues to run under Rosetta 2 on current systems, but will stop working entirely when Apple removes Rosetta in macOS 28 (September 2028). If you still rely on this scanner, your best option is VueScan, a third-party scanning application that has reverse-engineered support for the LiDE 100 and hundreds of other legacy scanners across all platforms. VueScan runs natively on both Intel and Apple Silicon Macs, is actively maintained, and offers significantly more advanced scanning features than the original Canon software — including film and slide scanning, batch processing, and AI-assisted image optimization. It is a paid application with a trial version available. Alternatively, macOS's built-in Image Capture utility may provide basic scanning support if the scanner is properly detected via USB. For a complete hardware replacement path, modern all-in-one scanners with native Apple Silicon drivers are now inexpensive and would eliminate driver compatibility concerns entirely.
