Apple has released 10.9.4 system update for OS X Mavericks. The update brings Safari 7.0.5 and a bunch of bug fixes, including one for an issue that prevented some Macs from automatically connecting to known Wi-Fi networks. The update also claims to improve the reliability of waking from sleep, while fixing an issue that caused the background or Apple logo to appear incorrectly on startup.
Like any other Apple OS update, OS X 10.9.4 also contains fixes for a bunch of security issues. The details of these issues can be found on Apple's website.
As usual, to download and install the update, click the Apple menu and choose Software Update to check for the latest Apple software via the Mac App Store, including this update. The update's size may vary from computer to computer when installed using Software Update, depending upon what earlier updates you had installed.
You can also download the manual update installer. This is especially useful when you need to update multiple computers but only want to download the update once. These versions of the standalone installers are available from Apple Support Downloads.
