A MacBook Pro from 2012 can upgrade to macOS Sierra 10.12, macOS High Sierra 10.13,

macOS Mojave 10.14 and macOS Catalina 10.15.

If you choose to upgrade to either Mojave or Catalina I would recommend you upgrade

High Sierra first.

How to get old versions of macOS – Apple Support


Go to the Download OS section and click on the OS you want to install.


Before upgrading make a full back up of your Mac.


Check that third party apps you use have updates available for the new OS.

Check that your printers/ scanners etc have updated drivers and software available for the new OS.


Connect your mac to your router via cable rather than rely on WiFi.

Do not use your mac while it is downloading

and do not use any other devices that share the same internet connection.


If the App Store says ‘Open’ then it is detecting a previous download of the install app

go to the Applications folder locate Install macOS ******.app.

Move it to the Trash, empty the Trash.

Restart, click on the link again, the App Store should say ‘Get' or 'Download'.


If you are considering upgrading to Catalina be warned it does not support 32bit apps.

Your Mac is probably running 32bit apps and these will need to be updated to 64bit apps,

some updates may be free, some may be paid. Use this app to discover which apps you have

are 32bit, https://www.stclairsoft.com/Go64/ then contact the developers of the software to see

if they are offering 64bit updates.
