as above.
I did a search on my catalog folder (on a mac so I used the find command/terminal) and no xmp file there. But I can see the imported preset inside a folder called "ImportedSomethingSomething" which is located inside an Adobe folder (in my case it's inside /User/myuser/Library/Application Support/Adobe).
Am I doing something wrong? How can I make Lightroom behave like what the setting says it should do which is "store presets with my catalog".
Thanks
