Apple on Monday released macOS Monterey 12.4, which takes Universal Control out of beta and brings anticipated refinements to the Studio Display’s webcam. However, even if you don’t care about those tweaks, you still shouldn’t drag your feet on updating. Apple has patched 54 security flaws and vulnerabilities in macOS 12.4, a whopping number that comes on the heels of an emergency patch (12.3.1) on March 31.

According to the descriptions Apple has supplied, several of the flaws are high risk and could allow an attacker to execute arbitrary code and take over your machine. Apple hasn’t divulged whether any of the flaws are known to have been exploited, but you should still update your machine as soon as possible. Based on documentation of the vulnerabilities, here are the most dangerous for regular users:
