Want to check for software updates in Mac OS Mojave?
You may have noticed that the Software Update mechanism is different in Mac OS Mojave than in other recent prior Mac OS releases, with system software updates no longer arriving through the Mac App Store ‘Updates’ tab (well, except for the initial download of mac OS Mojave).
Instead, software updates are now downloaded from System Preferences, which is a bit more like i OS, and older versions of Mac OS X too.
Perhaps there's been a power cut; maybe there isn't adequate space available on your Mac (we always recommend that you don't install with less than 10GB of space free or your Mac may struggle with the installation); maybe there are other problems with your Mac - it's worth running Disk Utility (you'll find it in Applications Utilities) prior to updating just in case.
It's always wise to run through a standard series of checks before you perform an operating system update on a Mac.
Pre-Mojave, you may be able to fix a stuck update by going to the Mac App Store, finding the software you are downloading, and pressing Option/Alt.
When you do so you should see the option to Cancel the download.
And in case you were wondering, the softwareupdate command line tool for installing Mac OS X updates through Terminal remains the same.
Installing new versions of mac OS on a Mac should be a pretty simple exercise.
Generally, if there's a problem with your software installation it will get stuck on the updating screen, showing an Apple logo with a status bar showing the progress as the software is loading.
