I'm migrating from a PC and am looking for a good photo management program. I'm not big on the Adobe subscription model, so Lightroom is out.

On my PC, I'm still using date coded folders and manually sorting things, but thought I might try out something different on the Mac.

While I like the built in Photos app, that it hides the original photos in bizarrely organized subfolders makes it useless to process the initial Raw photos in Nikon's NX software or to use Xpiks to upload them to stock sites.

What are others using?

I always liked the simplistic Picasa, if you can get your hands on an installer.  I think Google discontinued it.

For me the only choice on Mac was Photo Mechanic, because I shoot thousands of sports editorial pictures. There is nothing faster for photo selection. But after that, I am sending the selected ones to LR or PS. Sometimes I use only Exposure, which might be a great choice for you, as it also manages pictures quite well. Both can be bought, no subsc.

Everywhere you have try out period, so test it and stick with what is best for you
