emilev Hello there I'm on Mac... a new user. I try to import Powerpoint on Presntations... but it seems impossible. When I go in Settings... Powerpoint is unavailable. How to fix that please ? My Powerpoint is launched at the same time.
jlgtx PowerPoint is not supported in OpenLP on macOS, it's a Microsoft thing. Easiest workaround is to export PP presos to PDF, and import those PDFs as Presentations in OpenLP.
