How to enlarge thumbnails in Photos?
I need to see my photos in a larger format than thumbnails as I'm culling through those I want to keep and don't want to keep. How can I enlarge the thumbnails?
iMac, OS X Mavericks (10.9.5)
Have you already set the zoom slider in the upper left corner of the toolbar to the maximum size?
That is the largest size of the thumbnails you will get in Photos.
if you want to see a photo larger, double click the thumbnail to see the photo full size. Then use the arrow keys to step to the next photo.
