Copied profile not working

[Granite1]

I just installed Vivaldi on my MacBook Air. Then, after opening Vivaldi and quitting it, I deleted the Default folder from /Users/username/Library/Application Support/Vivaldi/Default

I copied the default folder from ~/.config/vivaldi from my Linux PC and pasted it into /Users/peter/Library/Application Support/Vivaldi/.

But when I open Vivaldi, that profile is not used, instead it uses the standard "virgin" Vivaldi.

What did I do wrong?

EDIT
I just discovered this Help page, and in the section Transfer the full Vivaldi browser profile, it says:

Move a copy of the Default folder from the source computer to the target computer

and

You must only move — and not make a copy — of an existing profile.

This is what I did wrong because I just copied the default folder, but how does "move a copy" work? I have never come across this before.

@Granite1 I guess you can copy Linux folder ~/.config/vivaldi to MacOS folder /Users/peter/Library/Application Support/Vivaldi

But i do not know if all work as the encrypted databases (containing cookies, logins, extension data, etc.) on Linux use a different keystore than on Mac.

But that is all i know.

The better way is to use Vivaldi Sync to transfer profile from one OS to another!

@DoctorG:

Good suggestion.

I did that, and bookmarks and extensions were synched, though not command chains.

I'll have to those, as well as my css codes, manually.
