Notes
Notes are more than just text. Jot down quick thoughts, or add checklists, images, web links, and more. Shared folders let you share an entire folder of notes with a group, and everyone can participate. Powerful new search optimizations help you find the right notes more quickly.
View your notes a new way. Gallery view allows you to see your notes as visual thumbnails, making it easier than ever to quickly navigate to the note you’re looking for.
Share folders. You can now share entire folders—including all the notes and subfolders inside. Share an entire folder with your family or team, giving everyone access so they can create or edit notes, add attachments, and even create subfolders. Click the Add People button 
and select a method for sending the link.
Tip: When you’re signed in with your Apple ID and iCloud is turned on for Notes, your notes are kept up to date on all your devices—so you can create a to-do list on your Mac, then check off items on your iPhone while you’re on the go.
Check off your list. Click the Checklist button 
to add an interactive checklist to a note—that automatically sends checked items to the bottom of the list. Choose Format > More > Uncheck All to uncheck all the items in your list and start over—perfect for reusing your weekly shopping lists.
Add photos, videos, and more. Drag a photo, video, PDF, or other document from the desktop. Choose Window > Photo Browser to add items from your Photos library to a note.
Add a table. Click the Table button 
to add a table to your note. You can even copy a table from a website or another app and paste it into your note.
Lock a note. You can lock a note with a password to make sure that only those who know the password can see the note. To lock a note, choose Notes > Preferences and click Set Password. Then select the note you want to lock, and choose File > Lock This Note.
