McAfee’s Code-Signing Problem with Mac OS X

Last week, McAfee accidentally revoked the digital key the company uses to certify applications that run on Apple’s Mac OS X platform. The incident caused problems for customers who wanted to install or upgrade their Mac antivirus products.

If you have been attempting to install or upgrade McAfee Security for Mac, you may have noticed that the application was blocked from running on the system. Temporarily disabling Gatekeeper did not allow installation to proceed.

Luckily, McAfee engineers resolved the issue and have provided an updated binary of McAfee Security 1.2 for Mac. The new installer is available on the IS&T Software Grid.

The latest information on the issue is posted here.
