Importing mail stuck after a migration to a new Mac
New MacBook. I used the TimeMachine backup from an external USB 3 disk to move the data from the old to the new one.
All went well. I open Mail and it starts to import mailboxes. Takes a long time. For hours it now hangs on this message:
Activity Monitor suggests that something is happening, right?
Is it worthwhile to let it like this over night? Or is this futile and should I go forward with deleting an envelope index after a forced quit and that kind of mess?
Please advice, most appreciated!
MacBook Air (2020 or later)
