For my work I need hundreds of open tabs in my Chrome. When I restart, Mac automatically connects to Wi-Fi and all tabs get loaded which consumes much memory. I don't want this.
What I have to do is manually turn off Wi-Fi, then launch Chrome. When all tabs get loaded with "Unable to connect to the Internet", I turn on Wi-Fi. This helps me not waste memory on unused tabs.
So, is there a way to force Mac not to auto connect to Wi-Fi? I still need it "Remember networks this computer has joined" since I use my company's secure network and I don't want to reenter all the credentials all the time.
