Open the app and the first thing it will do is check whether your system and security software is up to date, and inform you of any discrepancies.
Download it from its Product Page, unZip it, and move it into your Applications folder. My free utility SilentKnight can be a real boon when you’re having problems with software updates. Use SilentKnight to kick Software Update into action.Starting up in Safe mode (Intel Macs with the Shift key held, Apple silicon Macs through Recovery) is intended to make updates easier to obtain and more reliable to install, and often does the trick.Simply restarting your Mac can restore normal software update function, and the updates will magically appear in Software Update.If your Mac isn’t offering more substantial macOS and security updates which it should, there are several things you can try: Once it’s up to date again, you can enable the Content Caching server. The simplest solution is normally to disable the Content Caching server in the Sharing pane, then run SilentKnight on the out-of-date Mac, and allow it to install those outstanding updates. If your Mac appears out of date, particularly for the most recent versions of XProtect, and it gets its updates through a Content Caching server, that’s likely to be a bug that I’ve reported to Apple. Some macOS updates which should have been available weeks ago don’t appear in the Software Update pane.Some updates delivered through a local Content Caching server, particularly XProtect, have failed to install successfully.There are two types of problem that have occurred more frequently in recent months: Firmware updates can also fail when a Mac’s internal storage has been replaced, either as an upgrade or repair. It’s not an uncommon problem with specific configurations of certain models, most notoriously iMac17,1 with Apple-fitted internal SSDs. If you have the latest security update installed but your firmware is older than those listed, all you can do is raise this with Apple Support. SilentKnight automatically checks firmware version against an online database that I maintain, and spares you the effort of using those lists. If your Mac is running Catalina or later, it should also have the latest firmware installed. If your Mac can’t run any version of macOS after Mojave, all you can do is install the last released security update to Mojave, and that will install the most recent firmware available for it. It also means that the only way that you can update your Mac’s firmware is to install the most recent macOS or security update that it can run. That ensures that any firmware is matched with a compatible version of the macOS kernel and its many extensions. This article is a brief guide to solutions.įor many years now, Apple has only distributed firmware updates as part of macOS updates. Many of you have been reporting that your Macs are falling behind in their firmware, macOS, and security software updates.
