Where can I find default Microsoft fonts Calibri, Cambria? If I want to test or use default Microsoft fonts on my Mac, and I own a post-2006 copy of Windows or Office, I believe I can legally use Calibri and Cambria although IANAL. This would be especially helpful when collaborating with colleagues using Office products like Word, Excel, and PowerPoint. Right now, I get a warning like: "Calibri not found. Trebuchet MS used instead." Where can I find them?
To find and install default Microsoft fonts on a Mac:

Navigate HERE in your browser.
Download the .ZIP file.
Unzip it (double-click it).
Open the folder that appears.
Select all the .TTF files inside the folder.
With the files selected, right-click.
From the pop-up menu, choose &quot;open with → Font Book&quot;.
Click &quot;Install Font&quot; for each font.

Note: Changes to fonts take effect when an application is opened or a user logs in to the account or computer on which the changes occurred, see support.apple.com.
