Your Mac username appears both in the ‘Start’ folder and in the user account. This name is formed based on the full name you gave when you (or the administrator) created the account for the first time.
There may be many reasons that make you want to change the username of your Mac: you chose a name long ago that was not your real name and now you are looking for something more serious, you misspelled your name without realizing it or you prefer to use your full name in instead of the abbreviation that you chose in your day.
Whatever the reason, changing the username of your Mac is possible since Apple launched Mac OS X Leopard in 2007. It is a simple task since then, which can be carried out from the ‘system preferences’.
Even so, you will still find some limitations like:
- The name of the ‘Libraries’ folder must match the name you give. So if you hope to put a more comical name to that folder, but keep a more formal name as a username, you can not do it.
- Despite being a simple task, there is always a risk of changing something you do not want to change, so we recommend making a backup beforehand.
- You will need to log in to a different account in order to make this change, so you may need to create this new account (administrator) before.
If you need to create a new administrator account follow these steps:
- Open ‘System Preferences> Users and Groups‘.
- Click on the icon in the form of a padlock in the lower left corner and enter your password.
- Click on the ‘+’ symbol.
- Change the new account to ‘administrator’.
If you have forgotten your password, follow our tutorial on how to recover a forgotten password on Mac or MacBook.

Change the Mac username
Changing the name of your user is simple (assuming you have administrator privileges). However, you will see a warning (it scares you a lot) that will tell you that changing the settings could damage your account and make it difficult for you to log in.
You just have to follow the steps proposed below to change the username:
1. Open ‘System Preferences’.
2. Click on ‘Users and groups’, and then on the padlock icon in the lower left. You will have to enter your password.
3. Then click with the right button on the user account whose name you want to change.
4. Click on the only option that will appear: ‘Advanced options‘.
5. Change the name in the ‘Full Name’ field.
6. Restart the computer so that the changes are saved correctly.
These steps will change your username, but not the name that appears in the ‘Start’ folder. And as the message warns, the account could be damaged and complicate the ability to log in normally.
We were able to make the changes without problems, although upon logging in again, the process took a few more seconds of the account (probably because the device was assimilating the new information).
Rename the ‘Start’ folder of your Mac or MacBook
Changing the name that appears in the ‘Start’ folder is somewhat more complicated. These are the steps you will have to follow:
1. Click on the Apple logo and sign out of the account whose name you want to change.
2. Log in with the administrator account (different from the one you want to modify). If you do not have another administrator account, read the previous sections to learn how to create a new administrator account.
3. Go to the ‘Users’ folder. To find it you can click on ‘Finder> Macintosh HD’.
4. Open the ‘Users’ folder. Inside you will find the shortcut of the ‘Home’ folder that you wish to modify.
5. Click on the folder and on ‘Rename’. Write the new name, but remember to write down the name you are replacing as you will need it later.
6. You will have to enter the password of the administrator account you are using to save the changes.
Change your username
After changing the name of the folder ‘Start’, you will have to change the username or you will have problems since both need to match so that everything works correctly.
You will also have to change the name that appears in the field that shows the location of the ‘Start’ folder. To carry out this process, follow the steps proposed below:
1. Open ‘System Preferences> Users and Groups’.
2. Click on the padlock icon and enter the password for the administrator account you are using.
3. From the list of users, right click on the name of the account you wish to modify.
4. Select ‘Advanced Options’.
5. Change the field of ‘Account name’. Write exactly the same name you put in the ‘Start’ folder.
6. Next, you have to change the name in ‘Login directory’. Behind ‘/ Users / Gonzalez’ delete the name ‘Gonzalez’ and write the new one you have chosen. For example, if you have chosen ‘Piquer’, you will have to type ‘/ Users / Piquer’.
7. Click on ‘Accept’.
8. Close ‘System Preferences’.
9. Restart the Mac.
.10. Sign in to the account whose name you just changed.
If you have a problem logging in, check that the account name and directory are the same. Otherwise, everything should work correctly with your modified Mac account name.
