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.  For Best results use Safari to commence the download as Others may not work.


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


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


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


This will allow the Full Version of the newer version to Download ( about 12.xx GB ), then expand and only then commence the installation.


If there is Third Party Security Software installed, remove it before attempting to upGrade. It may interfere with both the download process and interfere with the installation process


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


Computer Qualifying for macOS 13 Ventura 


Computer Qualify for the Monterey upgrade


macOS Big Sur 11 hardware requirements


macOS Catalina 10.15 hardware requirements


macOS Mojave 10.14 hardware requirements


macOS High Sierra 10.13 hardware requirements


Make Time Machine Backup  is very useful 


Notation - Mojave is the Last version to support 32 bit applications / extensions and Drivers. Catalina, Big Sur, Monterey, Ventura supports only 64 bit and there is no workaround.


Suggest using Go64 to find 32 bit application before attempting the upGrade. Some or many of the Application already installed may require an update or upGrades to 64 Bit Version
