Keep getting error while trying to set up sync for the first time

GarageSale

If you are still having this problem, can you please give this a try?:

  1. In GarageSale, choose “Help” menu > “Open Library Folder”

  2. With the library folder open, quit GarageSale

  3. In that library folder find the “Synch.leveldb” folder and move it to the trash.

  4. Start GarageSale and try to enable synching. In the prompt select “Overwrite Data on Server” (if you are enabling synching on your main Mac).
