objective c - On macOS Cocoa, is there a way to capture the entire stdin and stdout and stderr of a process calling several CLI binaries?

Question

I am reverse engineering an open source solution which is very complex although I have the entire source code. This application calls several command line utilities, and I would like to develop a good debugging strategy for my clone. Is it possible to capture the entire CLI activity of the process ? I know that I could replace the original commands with some bash script and perform the needed logging, however I am on Big Sur, which means I have a read-only file system, and it is not easy to replace the binaries. I was wondering if there is a more lab way for achieving this. Thanks for any help.
