Hola, no tengo Mac. Primer paso: Descarca Openlp aqui y instala: https://openlp.org/#downloads
Alli hay una descripción como hacer:
Download OpenLP using the download button below
Open the downloaded file and drag the OpenLP app to your Applications folder
In your Applications folder, open the Utilities folder and run the Terminal app
In the Terminal app, type the following:
xattr -dr com.apple.quarantine /Applications/OpenLP.app
If you are on an Apple Silicon Mac, you may need to run this command too:
xattr -cr /Applications/OpenLP.app
Now OpenLP should open correctly.
Donde exactamente necesitas ayuda?
