Disassociate apple ID with iMac
I have an iMac that has had the same appel ID for years. I no longer want this email associated with my account. The account I am using now, is the one I would like to have on the iMac. How can I make this happen? Is is possible to remove the old (existing) apple ID and use a new one (this one)? If so, how can I do this? I am not very familiar with apple, so keep that in mind. Specific details would be appreciated! Also, getting rid of this email will not be an issue, as I do not purchase anything from the store.
