Fixes
Mac OS X 10.7.1 — With OS X Lion Update 10.7.1 (Client), Apple calls out only five specific fixes, and while there are undoubtedly a few others,
- Address an issue that may cause the system to become unresponsive when playing a video in Safari. Unfortunately it doesn’t address the video freezes that users of recent iMacs have encountered under Lion
- Resolve issue that may cause system audio to stop working when using HDMI or optical audio out
- Improve the reliability of Wi-Fi connections
- Resolve an issue that prevents transfer of your data, settings, and compatible applications to a new Mac running OS X Lion
- Resolve an issue in which an admin user account could be missing after upgrading to OS X Lion
If you have one of the just-released MacBook Air or Mac mini models, there’s a different update for you, the OS X Lion 10.7.1 Update for MacBook Air and Mac mini 2011 (Client) (68.86 MB). Along with the previously mentioned fixes, it includes fixes that:
- Resolve an issue where MacBook Air may boot up when MagSafe Adapter is attached
- Resolve an issue causing intermittent display flickering on MacBook Air
- Resolve an issue that causes the SD card slot in Mac mini to run at reduced speed with SD and SDHC media
