Signing PDFs on Mac without opening Preview's fiddly signature tool
macOS's Preview app technically supports adding a signature — captured via trackpad or the Mac's camera pointed at a paper signature — but the flow is buried in a toolbar menu and the camera-capture method is finicky to line up correctly.
PrivaPDF's sign tool works the same way in Safari or Chrome on macOS: draw directly with the trackpad, or type your name in a signature-style font, then place and resize it on the page — a more direct path to the same result.
