How to change user name? I am rookie in mac and first time when I got mac I set user name as Admin therefore all that associate with the mac begin with name Admin.

I would like to change this name to Aleksey

I found in System Preferences tab where it could be changed



But I am not sure that if I change name I will not get errors in consequences , because as far as I understand such way I will change path.

Eventually I am not sure that path will be changed in all apps where it has been taken

If my explanation not clear feel free to ask

Thanks in advance!
If you have sufficient space on your drive to duplicate your user account temporarily…


Copy your home folder /Users/old-username to /Users/new-username.

sudo cp -a /Users/old-username /Users/new-username

Create a new user account in Users &amp; Groups. Enter the new-username as the username when creating the account. You will be prompted with the following:


  The Users folder already contains a folder with the same name as the home folder for this account.


Choose Use Existing Folder.
Log out of your old-username and log in to your new-username.
Once you've verified everything is as it should be, you can delete the old-username account.
If permissions are incorrect, continue from step 7 of the next section.


If you don't have sufficient space to duplicate…


You even more so need a backup before proceeding with this method.
Create a new user account or use an existing secondary administrator account. This account must not have either old-username or new-username. Log in to this account. Make sure you are not using Fast User Switching and old-username is correctly logged out.
From this account, rename /Users/old-username to /Users/new-username using Finder.
In Users &amp; Groups, unlock the preference pane, right-click on old-username and choose Advanced Options…. You'll be presented with the pane you screenshot in your question.
Change Account name to new-username and Home directory to /Users/new-username.
Quit System Preferences. Do not log in to new-username yet.
Shut down your Mac and boot into the Recovery HD by holding ⌘R on boot.
Open Terminal from the Utilities menu and run resetpassword. A new dialog will be shown.
Select new-username from the accounts list, then click Reset for Reset Home Directory Permissions and ACLs.
Once complete, restart and boot normally, then log in with new-username.
