To create a sign, you can either use your Mac’s trackpad, camera, or iPhone. Keep reading as we’ll go over each one of these in detail.

Here’s how to create a signature on Preview:

  2. Select Open With from the context menu and click on Preview from the further options.

2. Use Your Camera.

Instead of using the trackpad, you can also use your Mac’s camera to add a signature. The procedure is pretty straightforward. The Camera scans the signature from a piece of paper and adds it to the document, providing greater accuracy and originality. 

So, before performing this method, sign on a white sheet of paper. Then, follow these steps:

  1. From the Preview app, begin by clicking on the Camera tab from the Signature button.

Follow the steps given below:

  1. Choose the Signature menu, and click on the iPhone tab from the Preview app.

  1. Launch the Pages app

Fortunately, there is a workaround through which you can add signatures in documents using Microsoft Word on a Mac. However, you will have to insert the sign in an image format. 

Follow these steps below to do it:

  1. Go to Microsoft Word from your Mac, and create a new document. 
  2. Afterward, click on Save as and choose Save it as a PDF
