macOS Catalina Upgrade

I currently have MacBook Pro 2018 with MacOS Mojave but I am unable to find a way to upgrade it to MacOs Catalina. I tried searching for it on App Store, apple website it is no where to be found. The update of MacOS Big Sur is available but I want MacOS Catalina. Does anyone know where and how to find the update?

MacBook Pro 13″, macOS 10.14

Open Safari and click on this link, 


How to get old versions of macOS – Apple Support


Go to the Download OS section and click on macOS Catalina.


Before upgrading make a full back up of your Mac.


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

https://roaringapps.com

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 Catalina.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 or Big Sur be warned they do 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 providing 64bit updates or alternatives.
