If your MacBook Pro is from 2012 then you should be able to upgrade your mac to Catalina.
It is according to Apple possible to upgrade from Mavericks to Catalina, but in practice people have been finding
the installation stalls. This is probably due to the fact that Mavericks uses the old HFS+ file system and Catalina uses
the newer APFS files system, it is when converting to APFS the installation stalls.
With that in mind I would recommend to do an interim installation of High Sierra, and then upgrade to Catalina from there.
Open Safari and click on this link, Firefox will not work.
How to upgrade to macOS High Sierra - Apple Support
go to Section 4 and click on Get macOS High Sierra
you will be redirected to the App Store High Sierra page,
it should say Get or Download.
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 High Sierra.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 that 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/. Once the list has been created you can then
contact the developers of the apps to see if they provide 64bit updates.
