Apple has released an update to OS X Mavericks, which takes it up to version 10.9.4 and resolves WiFi and sleep problems.
The software update is a 280MB package and while not a major update, Apple recommended that all of its users download and update their Mac OS X machines to the new version.
The firm said in its advice note: “The OS X Mavericks 10.9.4 Update is recommended for all Mavericks users. It improves the stability, compatibility, and security of your Mac.
“This update fixes an issue that prevented some Macs from automatically connecting to known WiFi networks, improves the reliability of wake from sleep, and includes Safari 7.0.5.”
Users should back up their machine before they install and update to 10.9.4. Those who do will find that an issue with dropped connections has been settled. Apple previewed the 10.9.4 release in two earlier betas, with the first one being released in May.
Apple’s next Mac platform is on its way for release later this year, called Yosemite, which brings a ‘flatter’ look and feel akin to the iOS 7 redesign from last year.
Apple released the update in the same week as its iOS 7.1.2 release with more changes, advising iPad and iPhone users to update their devices as it contains numerous security fixes.
In its supporting information Apple said that one of the update’s fixes could prevent attackers from accessing attachments, and another addresses a killswitch issue that could have allowed thieves to reuse stolen handsets. Of these the attachment issue seems the most pressing.
