Sharing a Mac workstation with family members, room-mates, or colleagues without dedicated account boundaries frequently leads to frustration. Unintentional file deletions, conflicting browser sessions, blended photo libraries, and uncoordinated application preferences can disrupt daily productivity. By establishing Multiple User Accounts in macOS, you create isolated sandbox environments where each user enjoys private home directories, independent iCloud synchronisation, and tailored desktop settings.
Understanding macOS Account Types
Before creating a new user on your Mac, determine the level of system authority required. macOS provides three primary account classifications:
- Administrator: Possesses complete system authority. Administrators can create and remove other accounts, install hardware drivers, alter network configurations, and override security policies. Keep administrator accounts limited to primary device owners.
- Standard: Designed for daily productivity. Standard users can install personal applications to their user folder, customise personal settings, and save files locally. However, they cannot modify system-wide files, install low-level system extensions, or alter other users’ documents.
- Sharing Only: Cannot log in to the physical Mac desktop. These accounts exist exclusively to grant authenticated remote file and screen sharing access across your local network.
Step-by-Step Guide: Creating a New User Account in macOS
Configuring user accounts in macOS Ventura, Sonoma, and Sequoia is handled inside System Settings.
1. Access Users & Groups Settings
- Click the Apple menu () in the top-left corner and select System Settings.
- In the left-hand navigation sidebar, scroll down and click Users & Groups.
- Click the Add Account… button located beneath your existing account card.
- Authenticate using Touch ID or by entering your administrator password.
2. Configure Account Details
- In the account creation sheet, select the account tier from the New Account dropdown (typically Standard).
- Enter the user’s Full Name (e.g., “Sarah Miller”).
- Review the generated Account Name (short name). This string forms the Unix home folder name under
/Users/sarahmillerand cannot be changed easily later. - Specify a secure password, verify it, and input an optional password hint.
- Click Create User to initialise the new profile.
Enabling Fast User Switching for Instant Account Transitions
Logging out every time another person needs to use the computer is inefficient. Fast User Switching allows multiple accounts to remain logged in simultaneously with background apps running, allowing seamless transitions via the Menu Bar or Control Centre:
- In
System Settings > Control Centre, scroll down to the Fast User Switching entry. - Set the toggle to Show in Menu Bar or Show in Control Centre.
- Choose whether to display the account as Full Name, Account Name, or a compact Icon.
- Now, clicking your profile name in the menu bar displays all active accounts. Selecting another profile prompts for Touch ID or password and switches desktops instantly without closing open windows.
Managing File Sharing and Shared Home Folders
Because macOS strictly enforces POSIX file permissions, standard users cannot browse other users’ Documents, Desktop, or Downloads folders. If multiple users need to collaborate on shared projects locally:
- The Shared Folder: Navigate to
Finder > Go > Go to Folderand enter/Users/Shared. Any file placed inside this folder is accessible to all local user accounts on the machine. - FileVault Authorization: If your Mac uses FileVault whole-disk encryption, newly created accounts must be granted decryption authorization so they can unlock the disk at initial boot. In
Users & Groups, ensure new users are enabled for login access.
Deleting or Archiving User Accounts Safely
When a family member or colleague no longer requires access to your Mac, an administrator can safely decommission the profile:
- Navigate to
System Settings > Users & Groups. - Click the Info (i) button next to the account you wish to remove.
- Click Delete Account….
- macOS presents three options for handling the user’s data:
- Save the home folder in a disk image: Archives the user’s files into a compressed
.dmgfile inside/Users/Deleted Usersfor safekeeping. - Don’t change the home folder: Leaves the home folder intact on the disk.
- Delete the home folder: Completely erases all files associated with the account.
- Save the home folder in a disk image: Archives the user’s files into a compressed
- Confirm your choice and click Delete Account.
