Can I lock my notes with my OS X device? With the most recent iOS update, Apple gave users the power to lock notes on their iOS device. Is this feature also available on OS X after the 10.11.4 update, and, if so, how do I use it? Or do I need to use my iOS device to lock my Notes?
There's a padlock icon on the toolbar of the Notes.app. You lock your note by clicking on it.
