Transferring files between two MacBook Airs
I want to set up a new M1 MacBook Air by transferring my documents and photos from my current 2014 MacBook Air (Big Sur 11.4). (I don't want to transfer apps etc, so I can get a clean start - I'll download the latest silicon versions and leave behind legacy remnants of old or unwanted apps.)
My documents folder and photos are in iCloud, and have all the files I want to transfer. Is it sufficient to switch on iCloud on the new machine - will it then download a local copy to the new machine? Or do I need to use Migration Assistant to do the transfer, and then switch on iCloud? I have a time machine backup on a rotational HD (Mac OS Extended (Journaled)) or a Carbon Copy Cloner backup (APFS) on a USB stick which I could use as the source.
And I can I continue to use either machines to edit or file documents in future, and access the latest version of a file from either - will they stay in step?
