macOS Monterey 12.7.6 Security Update

What macOS Monterey 12.7.6 Fixes

macOS Monterey 12.7.6, released July 29, 2024, fixes 42 vulnerabilities in 23 parts of the system, according to Apple's security advisory.

Apple says one of these flaws — CVE-2024-23296 — may already have been exploited. That makes macOS Monterey 12.7.6 an update to install now rather than at the weekend.

It is the newest security release for macOS Monterey on Apple's list.

Grouped by us from the impact Apple gives for each fix; the impact lines below are Apple's own.

Exploited Before the Fix

Apple flags a fix as possibly exploited when it has a credible report that the flaw was used against real people before the patch. This one is the reason to update today.

• RTKit Exploited

  An attacker with arbitrary kernel read and write capability may be able to bypass kernel memory protections. Apple is aware of a report that this issue may have been exploited.

  A memory corruption issue was addressed with improved validation.

How to Install macOS Monterey 12.7.6

On the Mac, open System Settings → General → Software Update. Macs that cannot run the newest macOS are offered the update for their own version there.

Security fixes are cumulative: any later release for the same version includes these as well, so if you are already past macOS Monterey 12.7.6 there is nothing to do.
