Apple brings Gatekeeper to OS X Lion with 10.7.5 update
Following the release of iOS 6 and OS X Mountain Lion 10.8.2 on Wednesday, Apple rolled out a software update for users still running OS X Lion, the company’s last generation desktop operating system. This update introduces Gatekeeper, Apple’s new security feature, and improves the stability, compatibility, and security of your Mac.
If you’re still running Lion and you’re not too familiar with Gatekeeper, it’s a new security feature that aims to prevent malicious software from being installed on your Mac. You can customize it to allow apps downloaded only from the Mac App Store, from the Mac App Store and from identified developers, or from “anywhere.”
Of course, the first two options will prevent your machine from installing any software you may have picked up on the Internet unknowingly, such as the recent pieces of malware that were found to be affecting hundreds of thousands of Macs. You can activate it if you’re worried about accidentally installing things that may harm your machine.
The complete list of changes and improvements in this release includes:
- Resolve an issue where icons in Launchpad may get rearranged after a restart
