simplest way to use SharePoint with Apple OS

I've been researching this for a while -- my new employer uses SharePoint for employee schedules & communications.

I have an all-Apple OS life, with my MacBook Air & iPhone.

Is there a *simple* way to simply access my employer's SharePoint communications & download the PDF schedules?

I do not want to put any of my Mac files on MSFT's OneDrive. I do not want MSFT to have access to any of my stuff on my Apple devices. I want to keep life simple. Suggestions welcome, thanks
