Answer
Back up important data, open System Settings and select the Apple Account, sign out, carefully choose which iCloud data remains on the Mac, then sign in...
Check prerequisites and the intended result
Before changing changing the Apple Account on a Mac, confirm the current account, trusted devices, recovery access, iCloud data status, purchases, subscriptions, and Find My before signing out. Write down the current value before changing it so you can restore only that setting if the intended result does not appear. Keep the relevant account, app, or system version available if official support is needed. Confirm the saved choice after closing and reopening the relevant settings panel.
Use the supported method
Review what data will remain locally and do not treat sign-out as a way to transfer purchases or merge two Apple Accounts.
Back up important data
Confirm iCloud has finished syncing and keep a separate backup of files that must not be lost.
Open Apple Account settings
Choose Apple menu > System Settings and select the account name at the top of the sidebar.
Sign out carefully
Scroll down, choose Sign Out, and review each prompt about keeping a copy of iCloud data on the Mac.
Sign in to the other account
Return to System Settings, choose Sign in, and authenticate with the intended Apple Account.
Review services
Confirm iCloud Drive, Photos, Messages, Find My and App Store settings match the new account.
Check that the change worked
The intended account signs in, trusted-device verification completes, and selected iCloud services synchronize without duplicate or missing local data.
Troubleshoot changing the Apple Account on a Mac
If activation lock, Screen Time, management, unsynced data, or unavailable two-factor access prevents a safe account change, stop broad resets and return to the last known state. Capture the exact error, versions, device or account scope, and failed step before using the linked official support channel.
