SOFTWARE DEVELOPER Apple released Mac OS X 10.9.3 on Thursday, bringing improved support for 4K displays and a number of fixes.
Mac OS X 10.9.3 Mavericks is unlikely to get many users excited, but its headline feature is improved support for 4K displays for those using the new Mac Pro or 15in Macbook Air with Retina display. This "improved support" enables "HiDPI" Retina scaling on 4K displays, which means that text should appear sharper with higher refresh rates.
Available to download now, the update also brings with it the ability to sync contacts and calendars between a Mac and an iOS device using a USB connection, a feature that previously had been removed in favour of over-the-air (OTA) syncing, along with VPN connection improvements and an updated version of Apple's Safari web browser.
The incremental Mac OS X 10.9.3 update also fixes a "serious flaw" in Apple's iTunes software that allowed attackers to pilfer user details from the service.
Apple said in its advisory, "Set-Cookie HTTP headers would be processed even if the connection closed before the header line was complete. An attacker could strip security settings from the cookie by forcing the connection to close before the security settings were sent, and then obtain the value of the unprotected cookie.
"This issue was addressed by ignoring incomplete HTTP header lines."
The updated version of iTunes version 11.2 included in the Mac OS X 10.9.3 release also brings with it improvements to the Podcast feature, while adding a new Feed tab that makes it easier for users to browse episodes of TV shows that they haven't seen.
Apple is widely expected to unveil the next generation of Mac OS X at its Worldwide Developer Conference (WWDC) next month, which will kick off on 2 June. µ
