Horizontal rule in Notes app for MacOS

Hi morgankrane,

I see you have a question about Notes in macOS and I'm glad to provide an answer.

While there's not a function in Notes to add a horizontal rule/line, you can add media files: Attach photos, links, and more in Notes on Mac

"Attach files, website previews, map locations, and more

1. In the Notes app  on your Mac, click a note in the notes list.
2. If you select a locked note, you can’t attach a video, audio file, PDF, or document to it.
3. Do any of the following to add an attachment:

• • From the desktop: Drag a file into a note.
  • From your Photos library: Drag a photo directly from your Photos library into a note, or click the Media button , select Photos, find the photo or video, then drag it to the note.
  • Directly from your iPhone or iPad camera: Click the Media button , then select Take Photo or Scan Documents to take a picture or scan a document with your iPhone or iPad and insert it in your note. (Requires macOS Mojave or later and iOS 12 or later.) See Insert photos and scans with Continuity Camera.
• From within another app, like Maps, Safari, Photos, and more: Click the Share button , then choose Notes.
• The Share button  doesn’t appear in all apps.
  • You can also select some text or images, Control-click your selection, then choose Share > Notes."

Using this, you might be able to add an image of a horizontal rule to create something similar. If this isn't quite what you're looking for, you can send feedback to Apple here: Product Feedback

Cheers

I just use lots of underscores.
