i1Pro
i1Pro is a framework component embedded within X-Rite's color management and profiling software suite, particularly i1Profiler. It handles communication with X-Rite's hardware colorimeters and spectrophotometers (such as i1Display Pro, i1Pro 2, and similar instruments used for display calibration and color profiling). The framework is used by photographers, designers, print professionals, and anyone requiring accurate colour measurement and ICC profile generation for monitors, printers and other output devices. It is not a standalone application but a system-level component that enables X-Rite's profiling software to interface with their hardware instruments.

1 suggestioni1Pro is a framework component embedded in X-Rite's profiling software, not a standalone app — it cannot be updated separately. The correct update path is to download and install the latest version of i1Profiler directly from X-Rite's website at xrite.com. X-Rite has been shipping native Apple Silicon builds of i1Profiler since at least version 3.4.0 (released 2021), so when you update the host application through X-Rite's official installer, the i1Pro framework will be replaced with its native arm64 version automatically. Simply download the current i1Profiler installer from X-Rite's downloads page, run it, and allow it to overwrite your existing installation — your colour targets, profiles and instrument settings will be preserved. If you are still running an older Intel-only version under Rosetta, this update will give you noticeably better performance and battery life during profiling and measurement tasks on M-series Macs.
