2015 Late Model iMac 11.8 OS Mac Email
When I open email on the bottom left it shows activity, such as "Copying 1 of 3 Messages", and my email is crashing and slowing down this computer extremely.
This is a new issue. I have not had any issues for years.
I also keep getting popups that state "Running Out Of Application Memory" and needs me to Force Quit apps that are not using hardly any bytes...megabytes not gigs. HELP
