Trying to upgrade a mid-2015 MacBook Pro running Mojave 10.14.6 to Catalina to keep it up to date with my iMac. Software update only gives the option to upgrade to Big Sur and there are no Catalina OS downloads in Support. Is it still possible to upgrade from 10.14 to 10.15?
MacBook Pro 15″, macOS 10.14
Did you really follow the instructions.
Did you open your Safari browser, Firefox and Chrome do not work for this
that is why I mentioned to open your Safari browser.
Now that you have opened your Safari browser click on the link below,
How to get old versions of macOS – Apple Support
Go to Download OS
Click on macOS Catalina
This will redirect you to the App Store
You will see the Catalina download page.
Note the date at the top right of the screenshot below.
I did this on a mac running macOS Mojave.
Yes, open your Safari browser and click on this link,
How to get old versions of macOS – Apple Support
Then 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.
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 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 providing 64bit updates or alternatives.
Thanks for the quick reply but when I follow the links through to the iTunes store it says the Catalina downloader is not available in the US... ?
What does the first line in my first post say.
If you are going to ask questions you should read the replies.
Yes, I followed the instructions but the link to download the Catalina installer from the Apple Support page leads to the message "Item Not Available," which is why I posted the original question.
Mojave is better than Catalina in my opinion. If you want to upgrade might as well go with Big Sur.
