Hi dschump

 

Welcome to the Community Forums.

 

I do not know about the Best Buy version of WSA but I believe that the Webroot version is compliant with that version of the Mac OS.  This is from the Webroot site for the WSA Antivirus version:

 

PC & MacOperating Systems

• Microsoft Windows XP 32- and 64-bit SP2, SP3
  
• Windows Vista 32-bit (all Editions), Windows Vista SP1, SP2 32- and 64-bit (all Editions)
  
• Windows 7 32- and 64-bit (all Editions), Windows 7 SP1 32- and 64-bit (all Editions)
  
• Windows 8 32-and 64-bit
  
• Windows 8.1 32-and 64-bit
  
• Mac OS X v.10.7.3 “Lion”
  
• Mac OS X v. 10.8 "Mountain Lion"
  
• Mac OS X v. 10.9 "Mavericks"
  
• Mac OS X v.10.10 "Yosemite"

So perhaps the Best Buy version is not up to the same level as the Webroot version. Please see this link for the Webroot WSA versions, licensing options & pricing.

 

I hope that helps?
