Mail gains new Mail Drop tech
In Apple's new OS X Yosemite, Mail has received several upgrades, including faster mailbox switching and Mail Drop, which lets people send attachments up to 5GB via iCloud. The technology is integrated into Macs but generates URLs for other platforms. Email and PDFs can now be marked up via a trackpad.
The company suggests that performance enhancements should allow up to two hours of extra battery life when streaming 1080p Netflix on a MacBook Air.
