what can I do if I try to migrate from old Window PC to new MacBook and the migration assistant shows authentication failed, unable to retrieve credentials for authorizing user.
I was able to resolve by resetting the system management controller (SMC) Depending on your version the instructions can be found here: https://support.apple.com/en-us/HT201295
For my new Macbook Pro with Intel chip, I turned off the computer then pressed command + option + shift then pressed the power button and held all 4 buttons for 10 seconds. Then turned my computer back on and all was resolved. Best of luck!
This worked for me too! Thank you!
This help with SMC reset to do my migration assistant from my time machine. Thank you.
