Brand new MacBook Air 13” M3 - will not finish initial Sonoma 14.4.1 software update - error

i just opened up my box with brand new MacBook Air M3 from the Apple Store today. The software version installed on bootup is Sonoma 14.3. So I got to see if there is a software update considering this is a new MacBook, it says Sonoma 14.4.1 is available….. after about ten minutes of the progress bar not moving , I get the error MacOS installer could not be downloaded. Contact apple support for assistance.


yes I tried restarting etc…. Is this common? What do I do?

MacBook Air 13″, macOS 11.0

I had the same issue with a MacBook Air 15 M3.


To be able to install 14.4.1 – and any other future versions if the issue persist:


  1. In the Apple menu select App Store
  2. Search for "Sonoma"
  3. Click the Get button


Il will download the installer app to your Applications folder (the installer app is about 14GB in size).


Once the download was completed I had to reboot the system as the automatic upgrade prevented somehow the installer to start – after rebooting I was finally able to upgrade by double clicking on the "Install Sonoma" app.


Hope this helps!
