Hi Jeremy
The one system is a 2010 MacPro 5.1, 2.4 Quad Core, 16gb Ram. Mountain Lion was a fresh install, and then upgraded to Mavericks. Currently running 10.9.4
The second system is a brand new 27′ iMac, 3.5GHz Quad-core Intel Core i7, 16Gb Ram. Factory installed Mavericks, currently running on 10.9.4.
Both edit suits were running completely independently off harddrives, disconnected from the SAN as it was being serviced. They were not even connected to the office network at the time.
