New Notes App for Mac
The Notes app for Mac in OS X El Capitan is upgraded with Evernote style features that will carry over to iOS 9 on the iPhone and iPad.
The new Notes app for El Capitan includes the option to create a checklist, add in URLs, photos and draw and sketch on your Mac. You can also save information from other apps on your Mac like photos and there is a new attachment browser that makes it easy to see the attachments you've added all in one place.
With iCloud, the new Notes information syncs to your iPhone, iPad and another Mac. This includes the status of items on a to do list.
