I changed my apple id password.
I see that my imac doesn't show up on my devices.
How do I update my imac with new password?
Question marked as
It should do so automatically as long as it can connect the App's servers on the Internet. The password is your Apple ID password, not your computer user password.
If your computer is not showing in your list of devices, make sure you are signed into iCloud on the computer with Find My set up.
