Hi there and welcome
What will happen is when you sign out of the Apple ID on the Mac and sign into another, you will lose access to any data on that Apple ID, so you need to copy the data to eg: an external drive first. This impacts anything linked to the account such as calendar, reminders, mail ect that the Apple ID is linked to
Then to assign the mac to a different Apple ID,
For a new Mac user account that doesn’t yet have an Apple ID, the option to create one is included in the System Preference panel for iCloud.
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
ok, you will have to in order to do this on the Mac.
Ok, go to https://www.icloud.com/find
If you only see Pages, Numbers, Keynote, and Settings on iCloud.com, your account just has access to iCloud web-only features and its not possible.
Else Click All Devices, select the offline device, then click Remove from Account.
Then it removes the account and you lose the data I indicated before
Here is a list of data that can be stored on iCLoud depending on what you set up
It does not mean the data is deleted, it just wont be on that computer anymore.
No, Else Click All Devices, select the offline device, then click Remove from Account.
ok, thats what I indicated before, if you do not see them then you have to do it on the Mac itself.
If you choose Erase Mac, that wipes everything on it and returns it to a new mac.
correct, we have checked this and confirmed.
Only option is either on the computer or via the Erase Mac.
If you would like any additional information or assistance, please do not hesitate to let me know.

2. Go to System Preferences --> Security & Privacy --> Click the lock to make changes. Make sure to keep it unlocked.
3. Return back to System Preferences --> iCloud --> Enable Find My Mac.
