Users can update to macOS Monterey 12.2 right now by going to System Preferences > Updates, but why is this update so important? Furthermore, why has it dropped less than a month after the macOS latest feature update?

MacOS Monterey 12.2 – Should I update?

According to the Apple support page for macOS Monterey 12.2 there’s a slew of bug fixes this time around, so don’t expect any fancy new features until macOS Monterey 12.3 at the earliest. The biggest fix is a security issue that’s plagued iOS, PadOS, and macOS users over the last month or so.

Safari has a bug that allows malicious intent by leaking tab and Google Account information. This bug can also affect other browsers such as Google Chrome, making this update essential. Users should update all affected Apple products at their earliest opportunity. Just make sure they have over 50% battery charge and are plugged into a mains charger to avoid any update issues.
