I got iMac late 2013, and tried to upgrade from OS maverick to MacOs Catalina. Able to download the MacOs Catalina but whenever i tried to install it, theres always a flash Error internet need to be connected?
My question is why is it not connected on the internet error even though my ethernet and wifi is working properly, i tried restarting it, unplugging/restarting my router. Its still the same outcome. Please help 😢
thank you 🙏
iMac 27″, macOS 10.15
