An Update would be updating OS X 10.11 to say OS X 10.11.6

An upGrade would be moving from OSX 10.11 to macOS 14.3 the latest version of Sonoma

The Age of this computer will Govern what newer version of macOS it will Qualify to install. 

Use About this Mac from the Apple Icon on Desktop - the required Information will be there.

With the above information in-hand - follow this How to get old versions of macOS and verify what version this computer Qualifies to install.

Does this computer appear as Listed and qualifying for an upGrade to a newer version of macOS ? 

Safari will open a redirect and open the Apple Store where the download can commence.

If Yes, suggest having at least 50 GB of Empty Space on the drive.

It will allow the Full Version ( about 12.xx GB ) to download, expand and then commence to install.

If there is Third Party Security Software installed - remove it.

It will interfere with both the download and installation process.

The below links will help identify which version of macOS  this computer may Qualify to run.

macOS Sonoma is compatible with these computers

Computer Qualifying for macOS 13 Ventura 

Computer Qualify for the Monterey upgrade

macOS Big Sur 11 hardware requirements

macOS Catalina 10.15 hardware requirements

Make Time Machine Backup  before doing any upDates / upGrades 

Done it! Closed down the Mac, unplugged it, waited a minute then plugged it back in, switched on and when I started up the Mac I was able to download the update.

I too am having the same issue trying to download Sonoma 14.3.1. I am not very tech savvy. Any assistance is appreciated. This is a 2018 MacBook Pro 2.3 GHz Quad-Core Intel 8gb 2133 MHz currently running Sonoma 14.1.2,

I also have the same problem with Sonoma 14.3.1. Enough storage space and no other issue. The download was stuck at the beginning and keeps no change for 1-2 days.

same. are you still having issues?

Although your Mac's issue may seem similar to that of the OP's, its solution may be completely different. I encourage you to start a new post so that it gets the attention it deserves.

Me too! Annoying

Try booting up your Mac in Safe Mode, and then, try updating it again.
