Apple MacBook Pro 17-Inch "Core i7" 2.4 late 2011Hi. I found my old mac laptop but dont remember my password. I would like to access without losing data or do hard reset if that's not possible. There arent any apple id or accounts associated any more. And when i try to access the menu with reboot command R i get the circle with a line through it so it must have been older than sierra.
Anybody know how I can salvage this?
