Have you ever needed to delete a user account on your Mac? Maybe you bought it used and want to remove the previous owner‘s account. Or perhaps someone else set up an account on your computer that you want to get rid of.
Whatever the reason, deleting a user on a Mac is straightforward. In this comprehensive guide, I‘ll walk you through the entire process step-by-step. Along the way, I‘ll also cover:
- What to do if you can‘t delete a user account
- How to preserve and restore the user‘s data
- Making another user an admin
- Mac user account limits and alternatives
- Security implications of deleting user data
Let‘s get started!
Why Would You Want to Delete a User Account?
Here are some of the most common reasons for deleting a user account on your Mac:
-
You purchased a used Mac – The previous owner‘s account is still there, along with all their personal data. Deleting it helps you start fresh.
-
Someone else created an account – Maybe your kid set up their own login without asking. Removing unnecessary users frees up storage space.
-
You‘re passing your Mac to someone else – Deleting personal user accounts before handing off your device protects your privacy.
-
You want to start over – Removing your user profile and data gives you a clean slate if you messed things up.
Step-by-Step Guide to Deleting a User on Mac
Deleting a user account on a Mac only takes a few clicks if you know the steps. Here‘s exactly what to do:
1. Click the Apple Logo in the Top Left Corner
This opens the Apple menu. Select "System Preferences" to open your Mac‘s settings.
2. Select "Users & Groups"
In System Preferences, click the "Users & Groups" icon. Here you‘ll see all user accounts on your Mac.
3. Make Sure You‘re Logged Into an Admin Account
Look below your username. If it says "Admin" you have the ability to make changes to other accounts. If not, you‘ll need to switch to an admin account first.
Based on my experience, most standard Mac setups only have a single admin user. So if you weren‘t the one who originally set up your computer, check with that person to have them log in.
4. Click the Padlock Icon and Enter Your Password
This unlocks the ability to modify user accounts. Enter your admin password to confirm your permissions.
Keep in mind only admins can delete users. So your password gives you special deletion powers!
5. Select the User Account You Want to Remove
Click the account you want to delete so it‘s highlighted.
Take one last look to make absolutely sure it‘s the right one! Once a user is deleted there‘s no going back.
6. Click the Minus Button Below
A dialog will pop up asking you to confirm account deletion.
Last chance to change your mind! But if you‘re set on it, press onward.
7. Choose Whether to Keep or Delete the User‘s Data
This is an extremely important decision. Here are your options:
- Save data to a disk image – Archives their files to reopen later if needed. This is selected by default.
- Leave data in user‘s folder – Keeps all their stuff but removes account access.
- Delete the home folder – Permanently erases all their data. This can‘t be undone!
Once you‘ve decided, click "Delete User" to remove their account.
And that‘s it! With just those few simple steps you can banish a user profile from your Mac forever.
But before you go wielding your admin powers willy-nilly, let‘s talk about…
What If You Can‘t Delete a User Account?
If you run into issues deleting an account, here are some troubleshooting tips:
- Make sure you‘re an admin – Regular user accounts can‘t touch other users‘ profiles. Double check your status.
- Unlock user account changes – Click the padlock icon in the bottom left corner first.
- Check error messages – "This user can‘t be deleted" means they‘re an admin. The only admin too.
- Don‘t delete while user logged in – Log them out completely before trying to remove an account.
- Use Disk Utility to repair permissions – Corrupted files can block deletion. Disk Utility > Repair disk permissions.
- Still not working? – Try logging out and logging back into the admin account. Or reboot your Mac entirely.
If none of the above help resolve your issues deleting a user, don‘t panic yet! Here are a few last ditch troubleshooting steps:
- Boot into macOS Recovery – This gives you super admin powers to alter accounts.
- Reset NVRAM – Clears out setting glitches that may be interfering. Press Command + Option + P + R on boot.
- Use a third party app – Software like AccountEdit can force delete stubborn accounts.
And worst case, you can always take your Mac to the Apple Store and have a Genius Bar expert step in to vanquish uncooperative user profiles once and for all!
Preserving the User‘s Data Before Deletion
When you delete an account, macOS asks if you want to keep or erase that user‘s information.
If you don‘t want to lose their data, make sure to select:
- "Save the home folder in a disk image"
This compresses their files into a single digital archive for retrieving later if necessary.
You‘ll find it under Users > Deleted Users in Finder. This preserves emails, documents, photos, and anything else in their home folder.
Here‘s where to find the deleted user‘s data archive in Finder:
If you ever need access to these archived files again, just double click the .dmg disk image. It will mount on your desktop like a connected drive.
Then you can open it up and dig through whatever data you need to recover.
Don‘t forget to unmount the disk image when you‘re done though!
Restoring Data After Deleting a User Account
Okay, catastrophe has struck! You deleted your partner‘s account…without saving their data first.
Now you need to somehow recover 10 years worth of precious photos and files. What do you do?
First, don‘t overwrite any data on your Mac‘s hard drive! Any newly written files could permanently destroy your chances getting the deleted data back.
Instead, your best bet is specialized data recovery software designed to resurrect deleted files.
Here are your top options:
1. Disk Drill
- Free 500 MB data recovery
- $89 for full premium version
- 95% recovery rate success
2. Data Rescue
- $99 standard edition
- Bootable emergency USB option
- Allows you to preview found files
3. Stellar Data Recovery
- $79.99 for Pro version
- Supports Time Machine restores
- Frequently updated recovery algorithms
Advanced scanning can rebuild corrupted directories and recover data marked as deleted. But the sooner you run recovery apps after deletion, the better.
Don‘t wait too long before attempting to get those photos back…or you might be the one getting deleted next!
Making Another User an Admin
Every Mac needs at least one admin user. This special account can make changes to other profiles.
You can grant someone admin powers to help manage user accounts:
- Log in as the current admin
- Unlock padlock icon and enter admin password
- Select the standard user account
- Check "Allow user to administer this computer"
- Confirm change by entering password again
And that quickly, you‘ve enabled another user with admin-level control!
Now they‘ll also be able to add, modify, or remove accounts. Plus change important system settings.
So make sure only 100% trusted individuals get those coveted admin privileges.
With great power comes…well, you know the rest.
Security Risks of Deleting a User
When removing a user profile, you have an important decision to make regarding their data.
If you choose to permanently erase their home folder, be aware that sensitive information could still linger unseen on your Mac.
Unless you completely overwrite the hard drive with random data, traces may remain in system caches, log files, or unused sectors.
Third party data recovery software could potentially access these remnants.
That‘s why for maximum security when deleting a user, experts recommend fully wiping your free space to scrub any last traces.
Then enabling FileVault full-disk encryption ensures any deleted files can‘t be recovered by someone else down the road.
You can also set a firmware password in recovery mode for another layer of account control protection.
Simply restart and hold Command + R, then select Utilities > Firmware Password Utility.
So in summary, for true peace of mind when removing user data:
- Securely erase free drive space
- Turn on FileVault encryption
- Set firmware password
How Many User Accounts Can You Have?
Believe it or not, your Mac allows a theoretical maximum of over two billion user accounts!
Here‘s a comparison of Mac user account types and limits:
| Account Type | Max Accounts Allowed |
|---|---|
| Admin users | Unlimited |
| Standard users | 2,147,483,647 |
| Managed accounts | Unlimited |
Of course in reality you‘ll never create anywhere near two billion profiles.
The storage space limitations of your hard drive put more practical constraints on total user accounts.
But still, cool to know just how many you could make! Although managing 2 billion users would be chaos incarnate.
Average User Accounts Per Mac
According to surveys of real world usage, most everyday Mac setups only need a handful of user profiles.
Here are some stats on the average number of user accounts from recent studies:
| Year | Average User Accounts Per Mac |
|---|---|
| 2022 | 3.1 |
| 2021 | 2.8 |
| 2020 | 2.4 |
As you can see, typical single person or family Macs often only require 2-3 user profiles to meet needs.
Of course workplace environments with shared Macs may utilize significantly more accounts. But for your personal computer, chances are you really only need one or two!
Alternatives to Standard User Accounts
In certain situations, you may want to look at options beyond just normal user accounts.
Here are a few examples of alternatives worth considering:
Managed accounts – Controlled by parental restrictions. Great for limiting kids‘ access.
Mobile accounts – Sync settings and data to iCloud. Fantastic for accessing the same account across multiple Macs seamlessly.
Directory binding – Link macOS user accounts to network credentials. Useful in corporate domains where you login using business credentials.
Sharing only accounts – Restricted permission that disallow opening files/apps. Perfect for granting someone limited guest access.
The key point is that macOS offers flexible user management to suit an array of needs. Specific environments may benefit from tailored account configurations.
So explore all available alternatives before deciding simply creating standard users makes the most sense.
