   - Navigate to `Finish` and if prompted to restart, select `OK`. Please note that this will power norns down fully, rather than restart it. That's okay! If you were not presented with an option to restart, simply put norns to sleep after the expansion completes.
   - Please note: norns will take a few minutes to fully boot after the filesystem expansion
   - You can verify the expansion has taken place by pressing K2 on the `SELECT / SYSTEM / SLEEP` screen -- `disk` should show around `26000M` (26 gb).

 If you have previously connected to a shield (either by this same IP address or simply `norns.local`) in the past, you may see a warning that the 'remote host identification has changed'. this is because the shield now has a new host key. The error will give you a filepath to your hosts file, but if you are on MacOS you can simply execute `rm -f ~/.ssh/known_hosts` in Terminal to erase the previous hosts file and start fresh.
