I have tried to sync the Iguana in all different ways and it just gets stuck:

It stays like this for hours and never completes sync and I can not access my balance
If it is a full node, just delete database and try again. Mine has been synced an hour ago (Mac).
sometimes just restarting iguana will get it to finish syncing up and generating all the files
if it is still stuck, try deleting ~/.iguana/tmp/KMD folder
especially if there was a forced quit of iguana, it could end up with bad data in the tmp folder
