MacOS Big Sur update not initiating

I have a macbook air mid 2014 on which I tried downloading the big sur 11.4 version from appstore, what is downloaded is just 28 mb. Tried running it, was able to click on agree to terms of software licence agreement, then clicked on continue when it said that it will be intalled on macintosh HD and this is where it stopped. Nothing else happening, no download initiating. Tried erasing and dowloading again, doesn't help. Tried terminal: softwareupdate -fetch-full-installer-version 11.4 and it didn't do anything. I also have 50 gb of free space.

Do you have any anti-virus apps, cleaning apps, or third party security software installed that may be interfering? If so, uninstall those apps by following the developers instructions. These types of apps are not needed on a Mac and usually causes more problems than they solve plus they impact system performance.


You can also try booting into Safe Mode and try running the installer again.


If your laptop is running macOS 10.12.6+, then you should be able to boot into Internet Recovery Mode using Command + Option + R to access the online Big Sur installer. This option will require at least 50GB of free storage space. Just make sure to select the destination for the install to the "Macintosh HD" item (default name for the macOS boot volume unless you changed it). Do not install to any "Data" volume.


Make sure to have a good backup before attempting to upgrade macOS in case something goes wrong.


You should always have frequent and regular backups.
