Cannot upgrade from High Sierra to Mojave on MacBook Pro 10.13.6

I have a MacBook Pro 10.13.6, 13" with Intel Core i5. I want to upgrade from High Sierra to Mojave 10.14. When I try to open the installer, it says that I need an OS of 10.14. Yet other sources indicate that I can make this upgrade. What gives?

MacBook Pro 13″, macOS 10.13

It appears from your description - you were attempting to install a Standalone UpDate of Mojave and Not the Full Installer which is required.


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. Make sure to use Only Safari to commence the download as Other may not work


Make a Time Machine Backup Before attempting. Notation - Mojave is the Last version to support 32 bit applications / extensions and Drivers. Catalina and Big Sur Only support 64 bit and there is not workaround.
