Welcome to this brief introduction to patching macOS apps. This guide presents a step-by-step process for patching the app without losing any entitlements so the application works as previously with our modifications.

There are also some hints on the patching process for electron apps and how to resign the app to allow dynamic patching (with a debugger).

I often modify various applications for testing purposes, and I thought I would write the process here to remind myself how to do it correctly, just in case I had a longer break from it (I hope not 🤞).

Both binary patching and cracking are techniques used to alter software behavior. Cracking differs in that it removes or disables unwanted features, such as copy protection and license verification.

While binary patching for personal use, like fixing bugs or enhancing software, is legally and ethically acceptable, cracking is generally considered illegal and unethical. It violates software licensing agreements.

I do not write this to encourage cracking. It is just the catchy name of the article.
