I keep the /Users directory on a separate hard drive, /Volumes/Media. I recently upgraded my main drive via a fresh install from Mavericks to Yosemite. I have two users (not including root): seamus (admin) and alex (standard). Seamus is my account. After completing the install, I went to System Preferences and changed my home directory to /Volumes/Media/Users/seamus. Success.
When I did the same for alex, however, I ran into trouble. When I logged in to that account, I couldn't open any of the folders in the home directory. I believe this is because the old Mavericks 'alex' user had UID 503 and my new 'alex' has UID 502.
So the question is, should I go in and try to manually change the permissions for each folder and file in /Volumes/Media/Users/alex to reflect this change? Or can I change the UID in System Preferences to 503 and be set? Or is there another action I should take?
Thanks.
