Update My mac to Catalina version.
Hi there, I wanna ask a question. I have a Macbook pro-17inch 2011, with macOS 10.12 "sierra" version. So can I update my Mac to the 10.15 "Catalina" version without any problems or any issues?
Any mac from 2011 cannot upgrade to macOS Catalina, you can upgrade to macOS High Sierra.
Open Safari and click on the link below.
How to get old versions of macOS – Apple Support
Go to the Download OS section and click on macOS High Sierra.
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'.
