How to restore MacOS from a larger disk to a smaller disk?

Question

macOS

There is a disk with installed macOS for 750 gigs, there is an empty ssd for 240 gigs. Task: move the system from one disk to another. The occupied volume on the first disk is about 170 gigs, so theoretically there should be enough space on the final disk. I tried to restore the disk through Disk Utility, it writes that there is not enough space on the destination disk :-( I also tried to restore from Time Machine, but it’s generally strange here, as soon as copying starts, it says that an error has occurred and asks for a reboot (I ran the utility in mode Internet Recovery).

Answer 1

shrink partition to 200 (utility disk), copy sector-by-sector (dd)
GPT should restore secondary write (in theory)

Answer 2

Regularly - through the time machine, you can simply restore it on a new partition. Or use Carbon Copy Cloner, it allows you to transfer the system to a smaller partition, so you moved from hdd to ssd.

Answer 3

1. Plug the old disk into the usb port
2. Run the Migration Assistant
3. Then everything is clear. You just don’t copy all the data (it still won’t fit) but what you need
