Which font extension is used on both PC and Mac? At the office I use a Windows running PC, in which tons of fonts are installed in .TTF, .OTF and .FON formats. 

I am using an iMac at home and sometimes I have to finalize my designs at home.

So, may  I use these fonts on my PC as far as I copy them on Mac? Or should I look for their Mac versions?
Mac OS X recognizes TrueType and OpenType fonts (.ttf and .otf) but not the PC bitmap fonts (.fon).

So depending on the copyrights of the fonts you may transfer the .ttf and .otf font files.

To install the fonts:


Under Mac OS X 10.3 or above (including the FontBook)
Double-click the font file > "Install font" button at the bottom of the preview.
Under any version of Mac OS X:
Put the files into /Library/Fonts (for all users),
or into /Users/Your_username/Library/Fonts (for you only).
