Can't install any new software, because the OS prompt doesn't appear
Hi community,
I have a problem of installing Illustrator. When I hit the 'install' button, a pop-up window said:
Admin password required
Check for an OS prompt and follow the instructions. We will need your administrator password to continue.
I clicked 'continue', and there was no prompt window. I have checked the privacy&security settings, and there is nothing wrong. I tried on other applications and also failed on them.
Does anyone have any clue? Many thanks in advance!
