When I edit photos in Photoshop and go back to my photos on my MAC, my edits are not there. I am looking at the original photos. Even in the albums. Did I miss a step when I installed Photoshop?
What's your workflow? (File type like PSD, for example?)
How are you moving the files between the two computers? Are you using a cloud service like dropbox, Creative Cloud or google drive, or are you using an external drive? Are you absolutely sure you are opening the same file that was edited on the PC?

Are you talking about editing your iCloud library and albums in your Photos app?
