If someone can test the Yosemite beta to see if the Mac Pro 2008 (3.1 Harpertown) has the 'Continuity' functionality that would be appreciated. My machine doesn't support 'AirDrop' and my understanding is that 'Continuity' is based on 'AirDrop'. However, I've also heard that upgrading the wifi card can enable 'Airdrop' functionality on this computer so perhaps that might be required for 'Continuity'? Any wisdom appreciated - Thanks!
