Just want to say thank you for all the help and advice on the Macbook situation. I think I managed to find one that will work for what I want to do based on what all of your advice. Thank you so much. I really would have been lost without your help.
Hopefully this will seriously help me with my work flow now once I have it in hand x

UPDATE: it looks like the MacBook I wanted is no longer available so I’m still looking at options x
