To speed up the process of syncing with the blockchain, a file called bootstrap.dat can be used instead of having your wallet download the blockchain block by block. The bootstrap.dat file contains the latest blockchain information
needed to have your wallet synced and up-to-date. By copying it to your $PAC folder, the wallet will pick it up and import the content.
Download and extract one of the recent files linked below.
Place bootstrap.dat-DATE.zip file inside of your $PAC folder: (your wallet needs to be closed!)
Mac OS: ~/Library/Application Support/paccoincore/
Run your wallet and let it sync using bootstrap.dat
Optional: By adding the command line: [-dbcache=1000], will use an extra 1gb memory and increase the importing process speed (example) $paccoind --dbcache=1000
Once sync is done bootstrap.dat file will be renamed to bootstrap.dat.old and can be safely removed.
Every time you copy a new bootstrap.dat file to the ~/.paccoincore folder, the wallet will update the blocks accordingly. If there is nothing to update, it will be ignored. It will, again, rename itself to the .dat.old name and overwrite any previous files.
U can monitor the import process by checking the ~/.paccoincore/debug.log file
