Apple has revealed steps to review its security policies in the wake of the Gatekeeper bug that recently affected new Mac users. Gatekeeper is a workaround used by macOS to ensure that only trusted software runs on a user's device. However, it seemed that the technology needed to be slightly reconfigured after a recent update to the Mac operating system. Shortly after Apple released its new macOS update, Big Sur, users started reporting problems opening third-party apps. Gatekeeper was reportedly unable to verify the developer certificates of these apps due to a server-side issue. The bug has also raised privacy concerns among users, with many wondering whether Apple has logged all apps launched by Mac users and whether this information could be used to give the Cupertino-based company a competitive advantage. Now Apple has provided a security update in an attempt to allay those fears.
