To check a Keynote presentation’s fonts on your Mac, open the file and choose Format > Font > Replace Fonts. Review the list for fonts marked missing, then install a missing font or replace it before sending. Finally, open the saved file on the recipient Mac, or send a PDF as a visual reference if the recipient cannot install the typeface. Keynote can identify missing fonts, but Apple’s documented workflow does not provide a command to package every font with a presentation.

Check the presentation in Keynote on your Mac

Open the exact presentation you plan to send. A missing-font alert may briefly appear when Keynote opens a file that uses fonts unavailable on your Mac. If you missed it, choose Format > Font > Replace Fonts; Apple says this is where you can see missing fonts and choose replacements. Open or close a Keynote presentation on Mac

In the Replace Fonts window, inspect the listed font names, especially any identified as missing. This is the practical check for the fonts Keynote flags in that presentation. The menu is also a replacement tool: choosing a substitute and clicking Replace Fonts changes that font throughout the presentation. Don’t choose a replacement just to clear a warning unless you intend to alter the design. Apple notes that if you later install the original font, Keynote keeps using the replacement until you replace it again. Change the font or font size in Keynote on Mac

Resolve missing fonts before sending

If the recipient needs to edit the Keynote file with its intended typography, arrange for them to have the same font installed and available in Keynote. If you have the font file, install it on your Mac with Font Book, then reopen the presentation and check Replace Fonts again. Apple documents adding a downloaded font through Font Book, which checks fonts for errors when installing and can validate a font file later. A successful Font Book validation checks the font file; it does not prove that the other Mac has the font or that every slide will look identical there.

If you cannot supply the original font, choose a replacement that is available on both Macs and inspect affected slides for changed line breaks, text wrapping, or crowded boxes. Those visual effects are a practical consequence to check after changing typefaces; the replacement command applies the new font everywhere the old font occurs. Save the revised presentation as a copy if you want to keep the original design intact. Avoid assuming a replacement is reversible by simply installing the original later: Keynote may still use the replacement until you explicitly change it back.

Confirm on the recipient Mac

For the strongest check, transfer a copy to the other Mac and open it in Keynote there. Have the recipient check for the missing-font alert, then open Format > Font > Replace Fonts to see whether Keynote flags any missing fonts. If they install a font, Apple’s instructions use Font Book; fonts can be installed for the current user or, depending on the chosen location, for anyone using that Mac. The recipient should check that the font is active and then review the slides in Keynote. Install and validate fonts in Font Book on Mac

A clean missing-font check does not guarantee identical appearance in every setup: Keynote’s warning specifically addresses fonts not installed on that computer. For an editable handoff, agree on font availability and inspect the recipient’s copy. If the recipient only needs to view or print the slides, export a PDF and send it alongside the Keynote file. In Keynote, choose File > Export To > PDF; Apple’s guide says each slide appears on its own PDF page. A PDF is a viewing reference, not the same editable Keynote presentation.

What the font check can and cannot do

The documented Mac workflow identifies missing fonts and lets you install fonts or replace them throughout a presentation. Apple’s cited instructions describe no collect fonts command or font-embedding setting for the Keynote file. So don’t assume that sending the .key file also sends the font files; confirm font availability separately, and follow the font provider’s terms when sharing or installing a font. When in doubt, include a PDF reference so the recipient can compare the intended slide appearance.
