With all new Opertating Systems, there are a couple changes. Well, thats a lie… there are MANY changes. That’s the point of the new OS. Right?

One of the changes in Apple’s new Mountain Lion OS is how to implement a new, HTML friendly signature. It’s actually very easy. Easier then the prior OS Lion’s way of doing the task.

So… lets hop right in on how to do this!

1. Open Mail.

2. Create a new signature (go to Mail > Preferences > Signatures. Find your email address on the left side and click it. Click the plus sign to add a signature. Write your name (or whatever you want really).

3. Open this folder “/Users/you/Library/Mail/V2/MailData/Signatures/”. Easy way to get here is to click GO on the App Bar while holding OPTION on the keyboard. This will make LIBRARY active an able to click. After that, just navigate along.

4. Open the latest .mailsignature file with a text editor

5. Replace everything under this code with your custom HTML (replace iso-8859-1 with uft-8 for umlaut support)

Content-Transfer-Encoding: quoted-printable
Content-Type: text/html;
Mime-Version: 1.0 (Mac OS X Mail 6.0 (1486))

6. Lastly, save the file and open the Get Info Dialogue and check Locked, so that it doesn’t get overwritten by Mail.

All done! Any question, feel free to leave us a comment below!
