Hi, I had Bitcoin Core up and running on my macbook. When I restarted the macbook this morning, Bitcoin Core started again downloading the entire blockchain. I selected the right folder, I have an external SSD drive on which I previously already had downloaded the whole blockchain. Also I tried to click "reset options", but after restarting bitcoin core it again doesn't connect with the existing blockchain on the SSD drive but starts downloading from scratch. Does anyone have any ideas how to fix this?
Ensure Bitcoin Core is closed, then open Terminal and navigate to the folder where Bitcoin Core is installed. Run the command to create a symbolic link to your blockchain data on the external SSD--
ln -s /Volumes/YourSSDPath/Bitcoin ~/.bitcoin
Replace "YourSSDPath" with the actual path to your external SSD. After that, restart Bitcoin Core, and it should connect to the existing blockchain on the SSD.
