keynote won't save my replaced fonts - I have to replace them every time I open the file. Help!

Hello SorrySelfTaught,

Thanks for the updated info.

I believe the answer to your question is based on your preferences. This follow on article shows the option to change your preferences to install your fonts to User or Computer. Change Font Book preferences on Mac - Apple Support

"Default Install Location

Choose where to install fonts:

• User: Fonts are available only to you and are located in the Fonts folder in your home Library (~/Library/Fonts/). To see your home Library folder, click the Finder icon in the Dock, press and hold the Option key, then choose Go > Library.
• Computer: Fonts are available to any user on this Mac and are located in the Fonts folder in the system Library (/Library/Fonts/). You must enter an administrator’s password to install fonts here.

System fonts you download from Apple aren’t installed in these locations."

Thanks and have a wonderful day.
