USED MIGRATION TOOL FOR NEW LAPTOP AND LOCKED OUT

https://support.apple.com/en-us/102633

Hi, I just got the new 15 inch MBA, and also use a 2019 15 inch MBP with an Intel processor. I did a Time Machine backup of my 2019 MBP, and then when I setup my MBA I used the transfer from Time Machine backup and it worked flawlessly. There is a communication problem between Intel Macs and Silicon Macs with the M1 and M2 chips, which migration assistant does not work.

How to migrate a startup volume from an Intel to an M1 Mac

Apple chose a different startup scheme for its Apple silicon models that prevents booting up from an Intel-targeted disk.

I'm puzzled how you could not have been asked to enter a new password (which, BTW, can be the same as your old password) during the initial Setup. Odds are you flew past it somehow.

At any rate, please see the link ku4hx provided.

A couple of observations about your post here:

• • Is there a reason you didn't start a new topic, rather than piggyback onto this one?
  • I disagree that Migration Assistant doesn't work between Intel Macs and Apple Silicon Macs. I used Migration Assistant to transfer everything from my 2016 Intel MacBook Pro to my new 15" MacBook Air a couple of months ago and it worked flawlessly. I didn't use a Time Machine backup external drive for the transfer, and instead used an Apple Thunderbolt 3 cable instead. Migration took less than 45 minutes for just under 1TB of data.
  • Can you explain why you'd want to boot up from your Intel MBP when using your MBA?
