This is for when you are transferring data manually from an old Mac, or in my case from a Time Machine backup. In my case it was because the logic board on the old machine died. It was easy enough to pull over my home folder and its contents. But where was the Stickies Database?
I had gone through the process about a year ago when I erased a disc and started over. But now I was doing it again and I couldn’t remember where the Stickies data is kept. Eventually after reading a couple of articles I decided to look in Containers, and that is where the data is kept.
Users/USER/Library/Containers/Stickies
From inside that folder, just drag the pList and the Data folder into the same Container on your new machine and you are all set.
