When downloading any OS from Apples Servers it is best to use a cabled connection,
do not use your mac while downloading or any other devices that share the same
internet connection. The Catalina download is 8.24GBs.
Upgrading from Yosemite directly to Catalina is a very large jump, have you prepared yourself.
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.
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.
The official Apple line is that you can upgrade directly to Catalina from Yosemite, but a lot of people have found that the
installation can stall. This is probably due to the conversion from the older file system (HFS+) to the newer APFS filesystem.
With that in mind I would recommend doing an intermediate upgrade to High Sierra before proceeding to Catalina.
High Sierra can be downloaded from here, open your Safari browser, do not use Firefox it will not work.
How to upgrade to macOS High Sierra - Apple Support
Go to Section 4 and click on Get macOS High Sierra
this will redirect you to the App Store High Sierra download page.
It should say Get or Download.
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'.
