Edit a macOS Preview and Print product datasheet PDF

Datasheets are spec tables with strict formatting. Update a value, a part number or a revision date without breaking the table. If it was made in macOS Preview and Print, you can edit the PDF itself. Letters already embedded are reused; for new letters in Apple fonts, you choose whether to use a close open font.
