+ Fix incorrect version selection on Mac Closes #2733 (except for Linux users)
Linux still blocked on previous Wayland breakage
- Windows was on 6.4 as some users reported slowdowns; we'll need to confirm whether they have come back in the next build. - Linux has been held back due to https://bugreports.qt.io/browse/QTBUG-114635
Since more often than not, we can't use the same Qt version on all platforms due to regressions.
