+
+You will be prompted to choose a directory to store the Bitcoin block
+chain and your wallet.  Unless you have a separate partition or drive
+you want to use, click Ok to use the default.
+
+![Bitcoin Core Welcome](/img/full-node/en-osx-welcome-to-bitcoin-core.png)
+
+Bitcoin Core GUI will begin to download the block chain.  This
+step will take at least several hours, and it may take a day or more on
+a slow Internet connection or with a slow computer.  During the
+download, Bitcoin Core will use a significant part of your connection
+bandwidth.  You can stop Bitcoin Core at any time by closing it; it will
+resume from the point where it stopped the next time you start it.
+

+you can just let it run to help support the Bitcoin network.

+*Optional: Start Your Node At Login*
+

+
+While running Bitcoin Core GUI, open the Bitcoin Core menu and choose
+Preferences.  On the Main tab, click *Start Bitcoin on system login*.  Click
+the Ok button to save the new settings.
