Unrecognised password for Apple ID on a new Macbook Air
Just bought a new MacBook Air to replace an existing MacBook Air that I am giving to my Daughter. When trying to set up my new MacBook the App Store asked me to adopt 5 Apps (standard Apple apps). The App Store then asked me to enter my User Name and Password to verify the process. I did this and got a message saying it was not correct. I have tried several times without success and have tried changing my password - again without success. Everything still works okay on my ole machine. Any ideas?
MacBook Air 13", macOS 10.15
