Change a Keynote theme on Mac
You can change the theme of a presentation at any time. Your existing slides inherit the attributes of the new theme, including object styles, title styles and more. If you customised anything on your slides — for example, if you changed slide backgrounds or the colour of text — you can choose to retain those changes.
Note: You can’t change the theme of a presentation you’re sharing with others.
Change the presentation theme
- Go to the Keynote app  on your Mac. on your Mac.
- Open a presentation. 
- Choose File > Change Theme (from the File menu at the top of your screen), then select a new theme. 
- Deselect the “Keep your style changes” tickbox if you want the new theme styles to override your style changes. 
- Click Choose. 
Some themes aren’t downloaded to your computer until you choose them or open a presentation that uses one. If your connection is slow or you’re offline when this happens, placeholder images and slide backgrounds in the presentation may appear at a lower resolution until you’re online again or the theme finishes downloading.
