So, long story short, my gf has just spent a week backing up all of her photos from the last 4 years onto her MacBook. In her infinite wisdom, she decides to update to the latest OS last night. After installing, the MacBook reboots a couple times with the Apple logo and the progress bar. She freaks out and manually powers down by holding the power button Now the MacBook shows the macOS Recovery screen. This is where I need your help. All I want is to get those pictures and videos off the HD. I couldn't care less about the computer or the OS. How can I do that? I know nothing about Macs or Mac recovery. She has never done a time machine backup, so I'm concerned that if I start messing with the disk utility or reinstall, we will lose everything. Can I just rip out the HD, stick it in an enclosure and pull the photos via USB from my PC? TIA!
