The vector files you received are compatible on both a PC, and a Mac.
 
However, vector files (EPS and SVG file types) can only be opened and edited in certain types of software, like Adobe PhotoShop or Illustrator.  If you are working with a professional printing company, they would most definitely have the software needed to open all of these files.
 
The PDF files can be opened in Adobe Acrobat. Regardless of whether you are using a Mac or PC, you should be able to open this file.
