OS X Mavericks 10.9.4 Build 13E19 Available

Another seeded build from Apple today and it’s build 13E19 of OS X 10.9.4. It’s been over a week after seeding the second OS X 10.9.4 beta and more than a month after the public release of OS X 10.9.3, which included enhanced support for 4K displays and syncing improvements with iTunes.

The beta is available through the Software Update within the Mac App Store.

As always, it remains unclear what improvements the new build will bring to Mavericks, but it is likely to include bug fixes and stability enhancements to the operating system.

Apple is also asking developers to focus on the following: Graphics Drivers, Bluetooth, Audio Drivers, Finder, App Store, and Safari.
