There are fixes for iOS, iPadOS, tvOS and watchOS, together with patches for all three supported flavours of macOS, and even a particular replace to the firmware in Apple’s super-cool exterior Studio Show monitor.

So: if you happen to can solely patch your show in just a few days’ or weeks’ time; as a result of it’s a must to plug your patched Mac into your susceptible show to replace it; and assuming that you just want log on to finish the replace…
…you could need to learn to begin up your Mac in so-called Safe Mode, and to replace from there.
In Secure Mode, a minimal set of system software program and third-party apps are loaded, thus slimming down what’s referred to as your attack floor space till you’ve accomplished the patch.
Sarcastically, albeit unavoidably, most third-party safety add-ons don’t begin up in Secure Mode, so another strategy is solely as well up with as many non-security-related apps turned off, in order that they don’t begin routinely once you log in.
You may quickly flip off auto-starting background apps within the Settings > Basic > Login Objects menu.
