new Mac M1, 2020 migration from MacBook Air 2013
If I set up a computer to computer ad hoc network between my old computer and new M1 MacBook Air(which I did) it appears this is a reasonable way to migrate the data into the M1 using Migration Assistant.
Is that true or are there reasons that make it better, faster, more reliable to use $100 worth of ethernet adapters and cable or use my Time Machine server (also wireless) or just connect my little Terabyte drive with an adapter to the new Mac(the Terabyte drive also has the backup's from Time machine)?
Finally, I notice that iCloud has already moved lots of stuff that is "shared" on iCloud after simply logging in the new M1 with my Apple ID. If so, when I delete all this stuff, originating from the old MacBook Air, will I lose it on the new M1 as a result? However, by going through the "migration" process will this be alleviated then since the hard data will move without using iCloud directly to the new M1?
thanks in advance for all your help!
