  7. Click the arrow next to the signature name and hit Remove.

Note: As soon as you digitally sign the document, a Signatures button appears at the bottom of your screen. In addition, your file turns into “read-only” to prevent modifications.

Bonus: How to Add Signatures to Excel on Mac

As a matter of fact, you can’t insert signatures in Excel Mac using the platform itself due to a different document format between iOS and Microsoft.

To add signatures to Excel on Mac, you might need the help of a third-party digital signature app. Among thousands of apps out there, we recommend the free and easy-to-use PDFelement. It supports MacOs10.14, 10.15, and 11.

Since the tool works on PDFs only and not on Excel directly, you’re required to convert your Excel worksheet to PDF.

After downloading the PDFelement to your Mac, what you need to do next include:

  1. Open PDFelement, hit Create to convert your Excel document to a PDF file
  2. Go to File > New > PDF from File and choose the file you have just converted
    PDFelement pdf from file
  3. Navigate to the “Markup” menu, click on Signature > Create Signature to add a signature to Excel
    create signatures in Markup
  4. Once you’re satisfied with your signature, hit Done
