Apple’s new Mac Pro relies completely on external ports for expansion, with six Thunderbolt ports, four USB 3.0 ports, one HDMI port, and two gigabit Ethernet ports. The folks at Macworld Lab put the Mac Pro’s expandability to the test, connecting 36 drives with a combined 100.63 TB of storage capacity, as well as a number of other devices. Even then, the combined devices together drew only 865 watts — less than a common hairdryer. follow link
Fun Way to Send Attachments in Mail
If you're working in a file that you want to attach to a message in Apple Mail, you can transfer the file to Mail easily: From the title bar of the file's window, drag the little proxy icon to Mail's icon on the Dock. Your Mac will make Mail the active application and open a new outgoing message, with the file attached.
(If your icon won't drag, the file probably isn't saved.)
