Скрипт колеса мыши не работает в книге MAC

Question

Я должен отображать статьи по горизонтали, который работает. даже это также работает на событие колеса мыши. Я имею в виду, что если прокрутить немного колесико мыши, то оно будет прокручиваться медленно, если колесико мыши работает быстро, тогда все статьи скользят очень быстро.

В Windows нет проблем (Chrome, Mozilla, Microsoft edge), но когда я проверяю в MAC(Chrome, Mozilla, Safari), он очень быстро скользит.

Не могли бы вы помочь мне в этом?
