I want to copy my entire OS/volume/disk (which is FileVault-ed) from on MacBook to another, whose volumes(s) are also FileVaulted. Assuming no OS incompatibilities between hardware, will a Carbon Copy Cloner (CCC) file/rsync-based copying/cloning from a MacBook source (regardless of T2) to a T2 MacBook work - and why or why not?
I do not yet see why a copy/clone to a FileVault-ed MacBook that's running Target Disk Mode (and for which I have the FileVault/disk/login password) will not work.
Comparison with Apple/macOS Migration Assistant (MA)
Reasons why I'm not yet jumping to MA:
- I do not yet trust MA, as it's completely new to me. I have decades of trust with rsync (which is what CCC employs) across many OSes (Unix, Linux, *BSD, macOS, Windows).
- I could not get MA to see my 40-gigabit Thunderbolt link between MacBooks (it kept wanting to talk over WiFi).
- Every time I'm tried an Apple-native solution (namely TimeMachine) to thoroughly and comprehensively capture all data/settings/content in a filesystem it's always failed me.
Nonetheless, I'm open to any and all pitches for MA.
A source told me CCC is "T2 chip incompatible" (or some such) and advised that Migration Assistant is the only (or at least only supported?) way to go. I'm skeptical.
My use case:
I regularly copy ("clone") one MacBook to another (or several others) for purposes of
- retaining a fully-redundant laptop in case my primary one fails for any reason (the primary purpose) and
- I can use multiple machines concurrently (so I don't have to carry one laptop everywhere) all configured with the same environment apps/config/settings. This use case is served well with advent of most dynamic data/content/files on my OS being Internet-served-and-synced (git repos, IMAP server, Dropbox/GDrive, etc) across my multiple MacBooks.
Typically source and target MacBooks are the exact same hardware model but not always. Regardless, I make sure there are no OS-incompatibility issues, namely: run same version of OS on each MacBook and that the copied OS is supported by the target MacBook.
