Go to the Umbrel app store and download the Bitoin Node application. This app is pretty much a wrapper of Bitcoin Core with a very nice GUI (sources here).
Launch it and go through the setup by simply leaving all settings at default. Your node will now connect to remote peers to download and verify the entire blockchain.
Processing will take longer as it approaches more recent years due to the larger number of transactions in later blocks.
Even with a great internet connection this will take from a few days to a week to complete. If you sync through Tor-only this can take even longer.
