Better scrolling and CPU management in OS X Mavericks, particularly for Mail and Safari

OS X Mavericks, which was just announced at WWDC 2013 features some power management and CPU usage improvements that should result in smoother scrolling and better memory management across OS X in general, particularly Safari and Mail.

Some of the largest gripes about Mail and Safari in OS X is the lag, especially with multiple accounts when it comes to Mail and multiple tabs when it comes to Safari. Some much needed improvements to memory management and smooth scrolling should make dealing with multiple tabs when browsing or large threads in Mail should be a much more smooth experience.

  • Better scrolling? Scrolling is horrendous after updating to Mavericks!
  • Indeed, I have a brand new MacBook Pro Retina 15" ( 2012 ). After I updated to Mavericks 10.9 I noticed that when I try to scroll in Chrome/ Safari ( all the same ), the screen goes up/ down in a real buggy, stuttering way. Very annoying, this makes my mac look like it can't handle the 'scrolling', come on Apple! Fix this problem...
