According to my bad experience of today, it took longer than 1h30 to
get the [Merge] button... Before, it took around 20 min.

Well, it only happed me once. Maybe macOS doesn't like Monday?

Anything in the Allowed Failures section, which is the macOS build and coverage, are totally optional and will not block you from merging. While they may keep the button from being green just to let you know some other things are still running, they won't block you from merging completely (that only happens if the docs or the main test run fail).
