    I had to scan lots of photos for a project. I placed multiple ones on the bed to go quicker. Is there any program for a Mac that will automatically extract them individually?

    you mean you have a single image file composed of multiple photos? and you now want to cut out the individual photos?

    make sure you have the "selection tool" on the toolbar in Preview.
    selection.jpg

    open the image, draw a box (selection) around one of your photos then, copy: [CMD][C], new: [CMD][N], save: [CMD]. repeat until done.

    I'm on OS X 10.9.5, Preview ver. 7.0. don't know if the tool is any different on later OSs. the big limit is rotate, preview will only let you rotate in 90º increments. if I need more fine detail rotation, I go into Photoshop. if you don't have that, Gimp is free.

    not automatic but free.

    I wrote a script to do this task for me. If you explain more about exactly what you are starting with, we might be able to adapt it for you.

    Some printer/scanners come with software that does exactly this. Maybe you already have what you need and don't realize it, or maybe you have to just download it from the printer/scanner's web site.

    The Mac driver for my printer/scanner includes a check-box for "Auto Selection: Detect Separate Items." If that option was available when you made your scans, you missed an opportunity.

    In my experience, the quality of software of this sort is quite variable. It's most successful when there's some sort of border around each image (whether an actual white border on the prints, or a gap between images on the scanner). Some apps will automatically straighten images, other times, not.
