macOS and [Live 10 and the "inner" Max 8] vs. [Max 7]

    Apr 23 2018 | 5:49 pm
    Hello friends
    On my computer Max 8 (packaged with Live 10) is visible from the operating system (Sierra) and for some reason notoriously becomes default applications for all Max patches (so I need to "right-click"->"Open Width" on the file to open it with Max 7). Do you have any tips how to permanently prevent packaged copy of Max from opening Max files (of course with the exception of files edited inside Live)?
    Btw. I experienced very similar (and so to say: annoying) issues several times with applications created in Max - sometimes Max standalones becomes default app for all Max patchers.
    Thanks in advance.
