I just downloaded several themes that I want to use. They are in /Library/Application Support/Keynote/Themes/
but I don't see them in the Theme Chooser screen.
Does anyone know what else I should be doing to install them?
Thanks!
When you open a template or a common keynote file, you can use the option File → Save theme... This puts your file in the necessary directory automatically and adds information about your theme to the welcome screen.
Typically they should be in:
~/Library/Application Support/iWork/Keynote/Themes/
You can copy yours there and they should show up; or when choosing a theme you can add them by navigating to the folder yours are in:
This is different in Keynote '09. The method I found that works comes from https://discussions.apple.com/message/8789217#8789217
It appears Apple has changed the way Keynote '09 accesses Themes. If you leave your 3rd party themes the way they were, Keynote '09 can't seem to handle it and the theme chooser does not open or work properly.
Apple's standard themes are now imbedded in the package contents of Keynote. (if you don't know what that means, don't worry. For those that care opt click show package contents ... Keynote>contents>resources>themes). You will have to find the third party themes you want to use. They may be located in the library > application support folder > iWork > Themes or somewhere like that depending upon how you set it up before.
Once you find the themes, I suggest moving them to a place like the desktop or your documents folder.
Once that has been done, Quit Keynote. Find the theme you want to "import" Double click on it. Keynote '09 should open. Once it is open, go to File>Save Theme.... you will be presented with the option to name the theme and store it in a folder here HD>Users>Home>Library>Application Support>iWork>Keynote>Themes.
Once you have saved it, quit keynote. Open Keynote and go to the theme chooser. Your new "imported" theme will be at the bottom after all of the Apple standard themes.
Repeat for each theme you want to import.
That might be overkill, but it did work for me.
