Problem: If your Agama wallet takes longer than 20 minutes to activate the best chain and load blocks, you could have some corruption in the database.

Solution: To clean out the Komodo folder and resynch. Leave only wallet.dat and Komodo.conf.  

1- Open the terminal 

(Stop Agama or the Komodo deamon if it is running)

2 - Navigate to the Komodo hidden directory "Library/Application\ Support/Komodo" by typing: 

cd Library/Application\ Support/Komodo' to 'cd ~/Library/Application\ Support/Komodo

3 - backup your wallet.dat file to your Desktop:

cp ~/Library/Application\ Support/Komodo/wallet.dat ~/Desktop/
(now you have a copy of your wallet.dat on your desktop. Copy/paste it in a secure folder. It holds all your privatekeys.)

4 - delete everything except komodo.conf and wallet.dat.

sudo rm -rf blocks fee_estimates.dat realtime chainstate signedmasks
database db.log komodostate debug.log peers.dat

5 - restart Agama on KMD Native
