[GangGreenTemperTatum]

• kudos and ty for the awesome project! 👏
• these ports fall within the dynamic or private port range are less likely to be used by standard services and applications.
• for example, during my experiencie MacOS was painful as i realized it was Control Center (native app) by default and involves having to troubleshoot this, remove containers/images/rebuild docker etc etc.. i thought this feedback may be helpful for other users :)
• some other code suggestions and linting
• i'm also raising another PR to fix #13 now :)
