Hi @john john Pter,
The "Connect to Outlook" feature relies on components available only in Windows. I'm afraid we cannot use this feature on MAC machine.
Personally, this is indeed a good addition to the current features of SharePoint if "Connect to Outlook" feature can also be used in iOS. Thank you for bringing things to our attention. We sincerely recommend you go to SharePoint Feedback community to provide your feedback: SharePoint · Community (microsoft.com). This is the best platform to let related team hear from you and make the products and services better for you and others.
Thanks.
