Microsoft Apple Security Setting: Microsoft has told about security in Apple’s Mac OS, which can give hackers access to user data by bypassing Transparency, Consent and Control (TCC) technology in the OS. According to Microsoft, this was informed to Apple through Microsoft Security Vulnerability Research (MSVR). As a result, Apple also released a security patch for it as CVE-2021-30970 as part of the security update released on December 13, 2021.

The Transparency, Consent, and Control technology, or TCC, is a subsystem that Apple introduced in macOS Mountain Lion in 2012. TCC technology is meant to prevent apps from accessing personal information of users without their consent and knowledge. Settings related to TCC can be found in System Preferences (System Preferences > Security & Privacy > Privacy) in macOS.
