Hi, I am a PC person, don't don't do a lot of mac help, but here's one I am baffled with. Its my mothers imac, she is in her 80's and can't remember much so its always challenging. I generally log in through teamviewer and straighten out her issues, I recently upgraded it to high sierra, and it was working fine but mom constantly forgets how to log in,etc. so she called the geeks squad last week, the kid was just sitting there, finally she kicked him out and now she is left with a issue. I cannot get to her across the country so here's what she says she has when she boots up:
a white window with a rectangle in the center, it switches back and forth to a oval image with two vertical lines through it. No touchpad response either, ideas??????
