Manage kids photos
Hi. Both of my kids phones were set up with default settings, so photos backed up to iCloud, which is now full and they need room on their phones. I just got a newer iMac so now running Ventura instead of High Sierra. I would like to pull the kids photos to an external drive. I just turned off iCloud for photos for my daughter's phone. Her phone does not show up in my Photos app on my iMac, nor in ImageCapture. On my older iMac, I could access other family members phones (I download my husband's photos to my Photos library, but I would like to keep my kids' separate). I am wondering if won't recognize the phone with a different Apple ID even if they are in my family sharing. I have seen that signing out of my Apple ID and signing into another one might cause issues. When I plug my phone into the iMac, it shows up under devices, but my husbands and kids don't. so...
1) can I use Photos to get photos off of other devices without signing into their Apple ID?
2) If I sign into another Apple ID on my computer will it merge our photos, etc and cause a mess
3)Would creating new users on the iMac keep our photo libraries separate?
4) would another option, like AirDrop be the only way to do it? Or maybe a drive that connects directly to phone
