The update includes a number of enhancements, including the activation of the Gatekeeper feature from OS X Mountain Lion that allows users to limit for security reasons what types of apps can be installed on the user's computer. The feature has been present in OS X Lion since OS X 10.7.3, but has been hidden from the public.
The 10.7.5 update is recommended for all OS X Lion users and includes general operating system fixes that improve the stability, compatibility and security of your Mac. It also includes Gatekeeper, a new security feature that helps you keep your Mac safe from malicious software by giving you more control over what apps are installed on your Mac.
The 10.7.5 update also includes fixes that:
- Resolve an issue where icons in Launchpad may get rearranged after a restart
- Improve Wi-Fi reliability for iMac (Late 2009 and newer)
- Resolve an issue using Spotlight to search an SMB server
- Improve compatibility connecting to Active Directory servers
