Results after changing the name of macOS user account and home folder
I believe I correctly renamed my MacOS user account and home folder, having followed these directions: https://support.apple.com/en-us/HT201548
But in System Preferences, Apple ID: the account name has not been updated in the device list. I loaded a backup of my prior machine to my new machine, and it used the name of the prior machine. I did this once before and I think the old name was updated to the new name...?after a delay? Or is there something more I need to do?
Until it is updated, the Apple Support sites, and Find My, have the old device name listed (with a "2" appended).
MacBook Pro 13″, macOS 11.3
