Unable to delete a User Account on Yosemite
Solution 1:
If you want to completely delete it, you should cancel the current process as it is saving the whole user account to a disk image –which is why is taking so long– and restart the account deletion process without saving any data when prompted.
From the Apple Support page:
Select the user you want to delete, then click Remove below the list of users.
Do one of the following:
- (…)
- (…)
- Remove the user’s home folder from the computer: Select “Delete the home folder.” The user information will be deleted and the storage space will be freed. If you want to prevent programs that read raw data from retrieving any files, select “Erase home folder securely.”
