“When you look at battery life on your computer, the real battery killer is CPU Load. When you look under the hood at CPU usage, it’s not a smooth line. It’s high use, low use, and back. All of that back and forth actually uses a lot of power. In Mavericks, we smooth out this usage; in doing so, we decrease these spikes by up to 70%,” maintained Apple CEO Tim Cook, in launching Mavericks at Apple’s WWDC developers conference.
“Next, lets talk about your memory. Nothing affects your Mac like its ability to use free memory. In the past, we’d have to write inactive memory to disk, a very slow process. Now, we can just compress inactive memory in place, freeing up all of that space instantly. As a result, we’re able to do things like improve the wake time by up to 1.5x”
The new Finder Tabs in Mavericks let users merge multiple windows into a single window, to reduce window clutter on the desktop. The new system tags let you tag files with names like “work” or “important,” to make files easier to locate.
For better multiple monitor support, Mavericks allows menus and docks to appear on multiple displays. Apple has also upgraded Airplay to let TVs work as displays.
Apple also announced improvements to Safari and notifications. “In the new Safari, we’ve got a brand new top site, where all of your apps are stored,” said Craig Federighi, senior vice president of software engineering.
Also new in Safari is a “reading list” feature on the home page that works like an eReader. In addition, you can now sync your passwords to an iCloud account, with 256-bit AES encryption.
In other enhancements in Mavericks, users will now be able to respond to emails and iMessages directly in notifications through a pop-up window.
Also on Monday, Apple announced desktop editions of two iOS apps: Maps and iBooks.
