How can I set up my iPhone 6s Plus to instantly connect with my 2015 MacBook so I don't have to manually wait for my wifi to see the iPhone and manually connect to it. I know the Samsung S7Edge reliably and automatically connects to my MacBook as a hotspot - it connects quickly even before my MacBook is fully booted. Connecting to the iPhone seems like a chore in comparison. Any tips or suggestions on how to make the MacBook and iPhone 6s Plus connect in a reliable and fluid manner?
