Change Registration of Mac to New iCloud Account
Have done some searching on the help boards but cannot pin this one down.
My wife has an iMac which is registered under her iCloud Account.
For support purposes and to collect all our Mac devices into one place, how can that registration be changed from her iCloud account to my iCloud account.
We have 10 or so Apple devices and they are all under my iCloud account except this one.
Thanks for any suggestions.
iMac 21.5″, macOS 10.13
