How to compare huge files with progress information

In a Unix command line context I would like to compare two truly huge files (around 1TB each), preferable with a progress indicator. I have tried diff and cmp, and they both crashed the system (macOS Mojave), let alone giving me a progress bar. What's the best way to compare these very large files? ### Additional Details: 1. I just want to check that they are identical. 2. cmp crashed the system in a way that the system did restart by itself. :-( Maybe the system ran out of memory?
