I have just added an SSD to my Mac Pro. I installed Snow Leopard onto the SSD but wanted to move the user directory off the SSD. However, I wasn't thinking, and rather than copying the user folders as created by the new installation to the HDD I instead altered the user directory under advanced user settings to point at the original HDD install. Further complicating things I specified a different initial user when installing - i.e Bob was user id 501 on the original install, and Fred user id 502. On this install Fred is 501 and Bob is 502. This means that when I pointed the SSD OSX install at the old HDD user directory (named Fred), I, Fred, didn't have any read/write permissions for the folder, Bob did. I know I have made this all sound complicated but I really am not sure what to do. Ideally I would wipe the SSD and start again but that isn't a trivial process. I am now feeling a little screwed and irritated with myself - I should never have pointed a new install at an old user directory complete with settings etc, and to compound things the user IDs are mixed up. Help would be very much appreciated!
