Hi Vero
Thanks for your help.
I get all the way through to the end of step 2 here: https://www.alfredapp.com/help/remote/setting-up/
Passphrase is accepted, phone is connected, phone appears in Alfred.
All looks good.
I get as far as seeing all of the buttons on my iPhone Remote, can press them and get the response to the press in the top-right of the remote screen "[Action Pressed] OK".
But the Mac I am connected to doesn't respond at all to the actions.
Thanks
Rob
