In Pages you can only change it for the document you just opened/converted in Pages. You can't preset which font it should convert to in Pages.
Calibri is a MS Office font. You could download and install a MSOffice trial if there is one that works on Mavericks and then delete the applications. The font will not be deleted so now if you convert a Word document in Pages you shouldn't get the error message.
I was able to make some changes by updating styles, but this has not fixed the problem that Pages thinks there are old fonts when I open the document.
To change styles I did the following:
- Opened the Format pane by clicking the Format icon in the title bar.
- Clicked on text that had an old font. The Font, treatment and size fields in the Text pane are blank in that case.
- Selected a new font name, set the treatment (Regular, Italic, etc.), and set the size as appropriate.
- In the top area of the Text panel the font name appears with a down-pointing triangle. I clicked the triangle to get the list of paragraph styles. The current style has a check mark. Hovering over it, a right pointing chevron appears. I clicked the chevron (careful, not the style name) to get a context menu with "Update Style" on it.
- Clicked "Update Style" to update all instances of text with that style.
It's possible this partly solved the problem, but I have about 100K words in this document, so it will be painstaking to check that it worked properly.
What template are you talking about because the default font in each varies.
New York hasn't been used as a font since the days of System 7 and the Classic Mac.
Are you using some ancient document, perhaps from AppleWorks?
These are the fonts included in OSX Mavericks, New York is definitely not one of them.
