Is there any way I can update macOS to Catalina after I used ignore command in terminal
I used this command
sudo softwareupdate --ignore "macOS Catalina"
Now, it is not showing any update, nor downloading from app store. How can I fix this issue to update to macOS catalina.
You can undo the command with
sudo softwareupdate --reset-ignored
You should also be able to use
sudo softwareupdate --fetch-full-installer
to get the Catalina installer.
