While ‘ we know it’s a great idea to download and install security updates, sometimes, just like any software release, a security update has issues. This is the case with the macOS Mojave Security Update that was released on September 24. It caused so many issues that Apple pulled, then replaced it with the Mojave Supplemental Update fix one day later.

Mojave Security Update

If you never upgraded to macOS Catalina, are still using macOS Mojave, and installed the Mojave Security Update sometime in the last few weeks, you may be experiencing issues.

Users have reported memory issues, slow boot times, Finder stalling, multiple system.log entries, Migration Assistant crashes, and more. The complaints have existed since it was released, yet it wasn’t pulled until September 30.

Possible fixes include reverting to a Time Machine backup, reinstalling Mojave, or upgrading to macOS Catalina.

Mojave Supplemental Update

Instead of those previously-mentioned fixes, you can also install the macOS Mojave 10.14.6 Supplemental Update that was released one day after Apple took down the Mojave update that was causing all the issues.

Apple says the update resolves app performance issues, a Migration Assistant stability issue, and an issue that may prevent you from creating a user account. Note that this update requires a restart of your Mac, while normal Safari updates do not. Don’t be alarmed — that’s supposed to happen.

The newest update will fix the account creation issues, Migration Assistant crashing, software update errors, Time Machine local snapshot errors, and memory issues.

Along with the fix, Apple also re-released the Mojave Security Update after initially pulling it. This makes it difficult to determine what you need.

Octopuses possess roughly 500 million neurons distributed across their body, with two-thirds located in their arms rather than their central brain, meaning each arm can taste, problem-solve, and react to stimuli independently of whatever the octopus is otherwise paying attention to.

When cosmonaut Valeri Polyakov stepped out of his Soyuz capsule in March 1995 after 437 consecutive days aboard Mir, doctors recorded him at several centimetres above his pre-flight height, and his spine had become so unaccustomed to gravity that the recovery team carried him to a chair rather than risk the compression of letting him walk.
When Bell Labs engineer Karl Jansky pointed a rotating antenna at the sky in 1932 looking for sources of transatlantic radio static, he kept picking up a faint hiss that peaked every 23 hours and 56 minutes, and he eventually realized he had become the first human to hear the center of the Milky Way.
