BitMaxz, thanks, but it didn't work. I added this text inside the bitcoin.conf file but after restarting, Bitcoin Core won't start at all anymore. It says "Error reading configuration file: parse error on line 2: -datadir=$HOME/Library/Application Support/Bitcoin/blocks, options in configuration file must be specified without leading - "
Sorry the above parameter is wrong.
Remove the "-" on the datadir it should look like this
datadir=yourblockdatafolder and then save.
It should look like this
datadir=$HOME/Library/Application Support/Bitcoin/
or replace it with this if you just want to point it to downloaded blocks.
blocksdir=$HOME/Library/Application Support/Bitcoin/blocks
