Hi alyssalip,
MacBook Pro and MacBook Air are using Max OS X. I’m sorry that this platform has not been supported. Including yours, we have received much feedback from customers needing this application. I would invite you to leave feedback to our product team via this link:

Customers’ feedback will be delivered to the product team. Now this feature has requested frequently, our product team will attach great importance to it. To meet your requirement, I believe this application will be available in the future.
I can complete understand this frustration. I also have a Mac machine and really want this OneNote application myself. I have the confidence that it will come in the short run.
In the future, if OneNote for Mac application is published, I’ll update the information here. You may also keep monitoring our forums to get to latest news. We appreciate your patience on this. If the app is published in the future, it may be an individual application or included in Office for Mac suite. You may also take your suggestions into the feedback. Currently, it is a good workaround that you can use OneNote Web App.
Thanks,
Kevin Cui
