Signing your business documents used to be easy. With the rise in online paperless documents, including your signature can be tricky. However, Apple's Mac OS X includes user-friendly signature creation embedded in the native Preview app. An image of your handwritten signature is captured once and can be included with a click in thousands of documents.

Program For Digital Signature Mac Mail

Capture Your Signature

Open the Preview app located in your Applications folder.

Sign your signature in the center of a blank sheet of white printer paper.

Select 'Preferences' from the 'Preview' menu to open the Preferences panel. Select the 'Signatures' tab.

Click the 'Add Signature' plus button at the bottom of the list of signatures.

Hold the signed sheet of paper in front of the built-in camera on your Mac, typically located above the screen. Hold a few extra sheets of paper behind the signed sheet to keep light from shining through and decreasing the quality of the captured image. Click 'Accept' to capture the signature.

Insert Your Signature

Make the 'Edit' toolbar visible by clicking the 'Show Edit Toolbar' at the top of the window.

Select the 'Signature' annotation tool from the Edit toolbar or by opening the 'Tools' menu, 'Annotate' submenu and selecting 'Signature.'

Click and drag to draw out a box for your signature in the place you wish to sign the document. Move or re-size to perfect the position.

Tip

• Preview's signature feature was added in OS X 10.7 Lion.

Warnings

• Annotations layers in Preview may not be compatible with all PDF programs.
• Export your signed document by selecting 'Print' and clicking the 'Save as PDF' option. This flattens the layers and makes sure everything is visible.

Download Java For Digital Signature

Hello,

In my keychain I have a certificate which uses my Gmail address. In Mac OS Mail, when I want to send an email from this address, Mail wants me to choose if I want to digitaly sign it with this certificate.

My problem is that when I do sign my emails, many people see weird behavior (a PDF attached, a warning for unsecure certificate...). Mail enables the signature by default, how can I disable this? I don't want to have to disable it for each email I send. I tried deleting the certificate, it works for a while but it comes back by itself in the keychain!

Thanks a lot for your help, have a great day.
