Use two methods to embed PowerPoint fonts. Embed TrueType and OpenType fonts with embedding permissions, and view them on Mac with Office 365. Attach fonts using the 'Universal' embedding method and view them on all platforms using the up-to-date version of Microsoft PowerPoint 2011 or above installed.
The 2.25 version of Presentation Font Embedder for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free Mac application is a product of Ariel Leviatan and Sahar Radomsky. The application lies within Design & Photo Tools, more precisely Presentation Tools. We recommend checking the downloaded files with any free antivirus.
From the developer:
Presentation Font Embedder gives you the freedom to use the fonts that you want by bundling them with your presentation files for display everywhere. Unlike PDF files, PowerPoint presentations are meant to be interactive and animated. Presentation Font Embedder allows you to keep most or all of your animations intact.
