Built-in Mac Tools for PDF Signing

Mac devices provide efficient built-in tools that make PDF signing straightforward, eliminating the need for additional software. Users can easily use these tools to sign documents directly on their Macs.

Markup is another useful tool embedded within the Mail app for quickly signing attachments. When an email contains a PDF attachment, click on the attachment to open it. Next, select the Markup icon which resembles a pen tip. In the toolbar that appears, choose “Add Signature,” offering options to create a new one with the trackpad, camera, or use an existing signature. Once the signature is applied, the edited PDF can be sent back, with the signed version seamlessly integrated within the reply, thus ensuring document integrity and enhancing communication efficiency.

Troubleshooting Common Issues
