Apple Updates Lion to OS X 10.7.1


[Update: Apple released separate standalone updaters for the MacBook air and Mac mini—we posted a separate article with links to all four versions of the OS X 10.7.1 update. - Editor]

Apple updated Lion on Tuesday with the release of “Mac OS X Update 10.7.1,” even though Apple officially changed the name of Mac OS X to OS X. The update includes four bug fixes, including sound and WiFI problems, and an issue dealing with transferring settings to a new Mac.


This is one of those rare operating system updates where Apple’s patch notes in Software Update match those on the company’s KnowledgeBase article for the update. Those patch notes are:

The 10.7.1 update is recommended for all users running OS X Lion and includes general operating system fixes that enhance the stability and compatibility of your Mac, including fixes that:

  • Address an issue that may cause the system to become unresponsive when playing a video in Safari
  • Resolve an issue that may cause system audio to stop working when using HDMI or optical audio out
  • Improve the reliability of WiFi connections
  • Resolve an issue that prevents transfer of your data, settings, and compatible applications to a new Mac running OS X Lion

The update is a 17.4MB download through Software Update. You can download it through Apple’s support site as a 79.29MB standalone updater.

Apple also updated Lion Server to 10.7.1, an update that included the same patch notes.
