Anybody with a Mac Computer GET IN HERE!

very random question but im seriously spazzing out over this. So I was at a friends house and I needed to charge my phone, so i plugged it into her little mac notebook and alllll my pictures came up and asked if i wanted to sync them. they were in the room and I didnt want them to see so I minimized it, because I didn't know how macs worked and couldnt exit -_-

anyways, I automatically assumed unplugging my phone would exit the screen. so I unplugged and shut without checking.

SO my question and request to you is. Plug in your iphone to your mac, your pictures should pop up. When you unplug your phone, does the screen exit?
