Users can go to Mac App Store to download the OS X 10.9.3. Apple recommends all Mac owners to download the update. The company promises enhanced compatibility, stability and operating system security with the firmware. Other changes and enhancements that users can expect include better syncing function between calendars and contacts for iOS and Mac. Users will find it easy to share contacts and details. VPN connections via IPsec are also more reliable under the new Mavericks. The firmware comes with a new Safari 7.0.3.
Although the update offers a "Retina" output mode support for the 15-inch MacBook Pro (late 2013), it does not offer the same feature to the 13-inch model. The existing Thunderbolt Display under Apple cannot handle 4K resolution. The support is only accessible to third-party monitors.
According to Apple Insider, the OS X 10.9.3 update went through a long beta period. It took nine pre-releases to developers before Apple decided to release it officially. The official release took place after Apple initiated the beta seed program to users for promise of "quality and usability feedback." Apple's program allows people to evaluate the pre-release version of the update.
Another report by iClarified highlighted another improvement from the OS X 10.9.3. The update expands the maximum VRAM under HD 5000/5100/5200 graphics chips by as much as 1536MB. The increase in VRAM is available for 2013 and 2013 MacBooks. Before, Apple can only provide a maximum VRAM of 1024MB. The increase also promises to enhance performance of the computers when working with 4K displays.
Users can check the display update by opening About This Mac > More Info > System Report > Graphics/Display.
