Handwriting app for macbook pro?
Can anyone suggest a good notetaking app for MacBook Pro? (I want to handwrite lecture notes instead of type). Do I need to buy a digital pen for this? Ideally, I want to open lecture slide files and be able to annotate them by hand. I have seen people doing this with iPads and am wondering if there is anything like that available for the MacBook Pro? Thanks.
MacBook Pro with Retina display, OS X Mavericks (10.9.4)
