It is very frustrating that a tiny update reminder popping out from the top right corner of your screen, every time you open your mac and you always tell it to remind you later. Yes, you can’t find a good time to update your macOS, and when you finally find time to update it often feels like a slog instead of what should be a few minutes of processing and a restart. If you're sick of waiting for the App Store and its sluggish interface, here's how you can speed up the process.
Use “Terminal” to Update macOS
The process involves a simple Terminal command and allows you to continue using your Mac as the update downloads and the initial software installation takes place in the background. This trick won't update third-party apps from the App Store, nor will it take care of apps from Apple you've downloaded to your Mac, like Xcode. It will update your operating system to the latest supported version of macOS, along with apps included in macOS from the get-go.
In the Terminal, enter the command "
softwareupdate -l" to tell your Mac to look for any available updates to macOS. If one is available, you'll see the update displayed in the command line, with the option to install it. You can install every update at once by typing "
softwareupdate -i -a" and letting the Terminal do its work in the background while you browse the web or take care of some editing. You'll need to restart your computer manually when the Terminal finishes downloading and installing the downloaded updates.
While the amount of time saved may vary depending on factors like your Mac's age or the software update size, skipping the App Store not only accelerates the update speed but also gets rid of the pain that is staring longingly at an unmoving progress bar. Users with older Macs, in particular, will likely appreciate this tip, as it saves having to fire up the Mac App Store altogether, which can be slow-going and sometimes even downright unresponsive.
