SFTP still works, but smb is a little easier.
On mac, if you type in smb://norns.local in the url bar of a browser, it will ask to open finder. There you can type we/sleep and then it will show and behave the same as if norns was an external hd or sd card
for engines, I believe you will still need to ;restart in the sc repl (or hit the reset audio menu item on the norns itself)
