By far my favorite new feature in Mountain Lion is the new Gatekeeper that hopes to keep malicious software from infecting your computer. Here’s a screenshot of Apple’s Service Toolkit (used for diagnosing computer issues at Apple Resellers and the like). It won’t let you install the software because the developer is an “Unsigned Developer.” Funniest thing I’ve seen in weeks.
Gatekeeper Feature! Apple Software is Unsigned Too!
