information about your operating system may be helpfull.
That would be Mac OS X Yosemite
Just copy over the font. It will be in /Library/Fonts or in ~/Library/Fonts. Copy it on a stick or use Airdrop between your two computers. You can also use Font Book (A built in application - use Spotlight (the looking glass in the upper right) to find it) to find the font if you don't know how to make the hidden library folders show up. Find the font in it. Select it and do a "export fonts" from the File menu. Export to your desktop. Put the exported folder on a stick or transfer using Airdrop and on the other machine open Font book and do a "Add Fonts" from the file menu.
Problem solved. Thank you.
