Three workthroughs considering options and issues in migrating to a new Mac, with info on late migration, macOS upgrading, and Thunderbolt adaptors.
Don’t just throw it in a box and send it off: what happens if its internal storage is replaced or wiped? What about protecting sensitive files? Does a T2 chip make this difficult?
More work to be done before your migration is fully complete: check your workflows, key security settings, disk health, licensing, backups.

Adds support for local snapshot statistics, Dark Mode, fixes a bug, and is now notarized for your added security.
Detailed comparison of how Time Machine backs up HFS+ and APFS volumes, including its use of local snapshots, with diagrams.
When Time Machine backs up an APFS volume, it works quite differently from the way it did on HFS+. Explored here using log entries from Mojave.
Practical tips for those intending to upgrade early, from checking compatibility, preparing workarounds, to making a copy of the installer.
