If you accidentally click through too fast on the Migrate Wizard steps, and choose to restore everything, fear not.
The new user you have created in the Migrate process will have all the files settings etc from which you can choose. (If you started the Migrate process from the Guest account, it still creates the new user over the top of the Guest account (huh?) - so that is one to watch out for.
But how do you access the files of the new user? Login as the newly created account I hear you say. Yes, but what if the password for that old restored account is long lost?!?!
Using sudo chmod -R 777 in the terminal is a bit scary, so an easier way is to navigate to the folder of the new user. (Log back in to your own user).
The simplest method is to drag the folder with a red no entry sign pops up this authorisation dialog
I wasn't sure if this method allowed all the sub folders to be copied..
So I also tried a slightly longer-winded way of changing the permissions:
From the folder in question, choose Get Info.
From there the trick is to unlock the padlock (bottom right)
And then ADD your account as a Full read & right permission using the + and the Privilege spinner
With that done, the drag an drop copy still prompts for authorisation, but appears to recursively copy everything.
So far so good.
