A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
on my old mac, when I open powerpoint, and create a new blank presentation, the page is shows is white with black text. If I insert a new slide, it is white with black text. This is normal. This how powerpoint has been for at least 10 years on all platforms. If l click on view-> slide master, all slides are white.
However, on my new mac, since today, all new blank presentations always get black slides with white text. If I insert a new slide, it is black background with white text. If I click on view-slide master, all slides are black. Before today it was fine.
I have no idea how powerpoint got "broken" on this mac, as I have never created a slide with a black background.
Any new presentation I create has all back pages. I need to find a way to fix it - go back to the "normal" white slides.
I guess one option might be to delete powerpoint, and reinstall it?
