1. if initially i wrote a code that uses seleniumlibrary and it works, i guess it depends whether the same logic or code can be kept when switching to headless browser yes?

Yes, it is straight forward. If you defined a variable for your browser just change it to the headless corresponding name. For example robot -v browser:headlesschrome ...
You only may need to adjust timings with Wait ... keywords. If you test first in local system, it should behave the same in CI/CD system.

2. sounds like you manage to use RobotFramework on macOS app. what ci/cd provider did you go with in that setup?

This is in-house solution, real hardware macMini as a node of Jenkins. But use it for testing with Safari and Appium (Android and iPhone), macOS apps never tried because not needed (but would go for Sikuli as first try).
