@khedges1 yes it is an old Mac, Still the same problem I had. Of course I have no idea if Opera have decided to not let it’s service be used by an old machine or that your Mac just doesn’t have the necessary requirements for todays Opera. You should be able to just Google that question. But if you try typing in offline download for Opera just see what ya get. It just somehow worked for me. No need to understand it.

@khedges1 My Mac is only 3 years old so I'm up to date with Sonoma 14.1.1. I just could not download it until I saw someone mention to try the off line download package? This didn't make much sense to me but somehow or other I downloaded an Opera package which finally allowed me to actually install it. More by brute force and ignorance but it worked. Try it.

Couldn't update opera on my mac so uninstalled it. I am now unable to reinstall it which is extremely frustrating. I have used Opera for many years and do not want to change now. I have downloaded the installer and it repeatedly says that it cannot download and try again with exactly the same result. Please help.
