i've migrated my photos from PC. Where will I find them now?

On what Mac, running what version of OS X?

Depending on what computer & OS X you have installed

the details may vary, as could suggestions...

Usually a new-user account is created and these items

may be found in there. Not sure if that relates to your

situation however.

You could look for them in Spotlight, if they'd have the same

file names, to see where they went, if not in a new account.

An older view, involving earlier OS X systems; may not involve PC.

Good luck & happy computing! 🙂
