PR Summary 🚀

• Improving Management of XProtect in CI Jobs 👮‍♀️ We've added some smart instructions to our CI process. It now politely instructs XProtect, a security feature in Mac, to take a breather before we start the code signing activity. This reduces potential interruptions, ensuring our code signing process always proceeds smoothly and efficiently!

• Conditional Running of Signing Part 🍏🔏 We've upgraded our script! Now, it will only run the code signing part if the APPLE_SIGN_IDENTITY secret is available. This means, we'll only sign our code when it's necessary, keeping our operation lean and avoiding unnecessary efforts. This beneficial step fosters efficiency, ensuring we're providing the best value for our time! 🙌

With these advancements, we're pushing our project forward, providing a better, more effective infrastructure. Remember, every small adjustment brings us closer to our grand vision! Keep up the fantastic work! 💫😃
