OS X 10.9.4 Update Released with Wi-Fi Bug Fix & Sleep Wake Resolution
Apple has released an update to OS X Mavericks, versioned as 10.9.4. The update brings several significant bug fixes and security updates, and is recommended to install for all Mac users running OS X Mavericks.
Notably, the OS X 10.9.4 update resolves a frustrating problem where a Mac would not automatically rejoin a trusted Wi-Fi network, despite being within signal range. A fix is also included to improve the reliability of waking from sleep, a problem that usually manifests itself by making a Mac feel unresponsive when the computer is asleep, frequently on MacBook laptops. The update also fixes an issue where the Apple logo would sometimes appear incorrectly during boot. Also included is Safari 7.0.5 and some other minor bug and security updates.
