New to iMac usage and need help
I'm new to using the iMac that was given to me. My former computer usage was Windows 7. My question is, when I initially turn on the iMac and before I select a browser I see things on my screen that I don't want there. I see what appears to be screens connected to what appear to be my email account and messaging? How did those windows/screens appear without me requesting them? More importantly, how do I make it so that those two screens won't appear when I initially turn on my iMac? Sure would appreciate some help. Thank you.
iMac 27″, macOS 12.7
