Mia: Account From PC
Maria: New Account
You should delete maria and use mia, because it is probably easier that way. So first move anything you want to keep to Users>Shared and then follow the instructions below
THIS WILL DELETE ALL ITEMS IN THE NEW ACCOUNT... YOUR MICROSOFT WORD WILL STILL BE IN THE APPLICATIONS FOLDER THOUGH
Open the Mia user and make sure it funtions well. Then logout. Open the maria user and go to the apple menu () in the upper left hand corner and select system preferences. click the padlock to unlock it and type the admin password (for maria..) then select mia and make sure Allow User To Administrate The Computer is checked.
accept any dialogues after reading them, then logout. Your should have full access with Mia.
now with mia, open up the Users & Groups pref pane, unlock it, and select Maria. Then click the -- . Select delete the home folder, and Maria will be gone. Everything you moved to shared can be found in the same place
I have a similar issue, but now involving an extra account...
I did the iMac setup out of the box and set up a user account let's call it "TrinGSter", but skipped the option to migrate any files at the time of original setup.
Then I ran the Windows migration assistant and as I wasn't sure how it would go and didn't want to port huge volumes of useless data across, so I only copied the music files. The migration assistant prompted me to create a new account "Tringster1". I then copied the music across, - planning to delete "TrinGSter" as described in the OP.
What I thought I was then going to do, was run the migration assistant once again and migrate the rest of the PC files - photos, docs etc. into the account I'd created "TrinGSter1. The problem is, it says this account already exists and I have to use a new name, so now it's prompting me to create a 3rd account.
This is now all starting to get a bit messy, as I'll have to create TrinGSter2, copy the files from that into Tringster1 and then delete the original TringGSter.
Is there an easy way to do this? I have no idea how to movefiles round on the iMac, I only unboxed it yesterday and am getting in a mess already!
