convert .mailsignature to text?
In upgrading my OS to 10.11 I lost 120 email signatures created over 15 years. Seems there's no way to import them back into Mail via Time Machine, but is there any way to convert the signature files to text? Tried opening them in TextEdit, in Safari, and a couple other apps, and while the needed text is there, it's surrounded by meaningless symbols . I want to get right to the actual text so I can copy and paste. Any way to do it?
